QUESTION 1DRS rules can help satisfy availability concerns within a cluster; however, if used extensively, they may cause aperformance issue with vCenter.

A. TrueB. False

Correct Answer: ASection: (none)Explanation

Explanation/Reference:Explanation:DRS rules can be extremely useful for a number of reasons, such as redundancy, network bandwidth, andperformance management. However, if they are used extensively, functionality such as DPM may become lesseffective (that is, hosts will not be able to power off due to rules and will use more power than required).

Chapter 4, Management/Platform Design

QUESTION 2You are reviewing a VMware vSphere 5 cluster design. The system is designed to run DPM in fully automatedmode. DPM in fully automated mode ____ evacuate all templates when placed into standby mode.

A. willB. will not

Correct Answer: BSection: (none)Explanation

Explanation/Reference:Explanation:DPM will not move powered-off virtual machines or templates. A real-life workaround is to turn off fullyautomated DRS for these machines on a case-by-case basis and register them to a specific host in the clusterfor deployment usage.


QUESTION 3Has the configurable option "Failure Detection Time" in VMware HA has been removed in vSphere 5?

A. No. It is an advanced setting.B. Yes. It is no longer needed due to additional storage checks in the VMware HA isolation response process.


Explanation/Reference:Explanation:vSphere 5 will use datastore heartbeats in a disaster. Thus, this setting is no longer available or supported inVMware vSphere 5.

Chapter 4, The Importance of vMotion, VMware HA, and Fault Tolerance

QUESTION 4

You are designing a VMware HA cluster. Due to project requirements, it has been agreed that the admissioncontrol policy is based on the number of host failures tolerated per cluster. However, because there are anumber of small web servers and one large database server with large reservations, the slot size has beenmanually configured. What is the impact of this configuration?

A. DRS will not automatically defragment the resources in the event of a failure.B. DRS will automatically defragment the resources in the event of a failure.C. DPM cannot be used in this configuration.


Explanation/Reference:Explanation:With the rebuild of vSphere 5 HA functionality, it is possible for VMware HA to ask DRS to defragment a clusterif systems are not going to restart correctly. However, this functionality is disabled if the default or automatic slotsize calculation is changed using the override setting. In situations like this, from a design perspective, apercentage-based admission control policy would be more beneficial.


QUESTION 5You are designing a vSphere 5 HA cluster. One of the requirements is to ensure full collection of log files in theevent of an issue. Which of the following is correct? (Choose two)


A. By default, ESXi logs are not persistent following reboots.B. The logs should be forwarded to a syslog server or vCenter dump collector.C. The ESXi logs are persistent through reboots.

Correct Answer: ABSection: (none)Explanation

Explanation/Reference:Explanation:By default, ESXi hosts do not store logs persistently through reboots. To ensure full visibility of logs, a syslogand/or vCenter dump collector is required for compliance and root cause analysis.


QUESTION 6You are designing a VMware HA cluster as part of a solution for a large enterprise. One of the specificrequirements is to remove the risk of impact to a DRS outage due to possible fragmentation of resourcesleading to performance issues. Which of the following statements is correct?

A. VMware HA will automatically protect DRS in the event of a HA event.B. A virtual vCenter cannot be used in this solution.C. vCenter heartbeat would need to be implemented to protect the vCenter and dependent services DRS uses

for this level of protection.

Correct Answer: CSection: (none)Explanation

Explanation/Reference:Explanation:The vCenter can be protected by VMware HA but is a requirement for HA configuration. The vCenter is also arequirement for DRS, DPN, network vMotion, and vMotion. For cases in which functionality such as this cannottolerate outages of several minutes in the event of a major event, VMware has a product called vCenterheartbeat. It can give true application protection without an outage to the vCenter application.


QUESTION 7A guest VM should be sized using ____________. (Choose two)

A. minimum applications specificationsB. initial workloadC. anticipated workloads

Correct Answer: ACSection: (none)Explanation

Explanation/Reference:Explanation:Allocated resources are shown in the guest operating system and are not guaranteed. The amount depends onthe unreserved resources available at the time. Assuming no functionality issues, you can configure aproduction application to be guaranteed its projected workload, and the system should deliver. Without areservation, there is potential for a performance impact if there is contention.

Chapter 5, Virtual Machines--From the Design Perspective

QUESTION 8You are a VMware architect designing a solution for a client with an existing site who wishes to build a disasterrecovery site. The operations manager has presented some information in the kickoff meeting. The company has 1,000 VMs, and the average VM has the following specs:

18 GB memory2 vCPU100 GB

The company already has an existing vendor relationship with a hardware vendor and would like to keep theexisting storage solution roadmap in place.

The following requirements are stated:RTO: 15 minutesRPO: 15 minutesUptime: 99.99%

The existing vendor relationship is a ______________.

A. risk to the projectB. constraintC. vision


Explanation/Reference:Explanation:An assumption could impact your design. It is good to ensure that project team and wider business are awareof assumptions and that they are agreed and validated as part of the design consideration process.

Chapter 2, Gathering Information and Spotting the Gaps

QUESTION 9You are a VMware consultant working at a small managed services company. The company has won acontract with a large company, Company A, to host its test and dev. platform, with the chance on annual reviewto host the production platform.

Although you have been engaged early in the project due to business requirements, the budget for the projecthas already been combined with that for another DR project for another company, Company B.

The thought process for this decision is that, if needed, the test systems from Company A have a lowerrequirement in the unlikely event of Company B having a DR event.

All the items have been bought and are to be delivered. Your role is to take the equipment provided andconstruct, develop, and implement a scalable working vSphere platform.

The following requirements are stated:

Company A's test machines must be provided with sufficient resources for BAU.Company B's systems must be made available with minimum impact to Company A.The RTO for Company A is seven days, with an RPO of one month.Company B's RTO is 1 hour, and its RPO is 15 minutes.

The use of a shared infrastructure used in this way is a constraint to the project.

A. TrueB. False


Explanation/Reference:Explanation:An item from the current state analysis that would restrict or change a design choice is potentially a constraint.These factors can limit the design and in some cases prevent the realization of the project vision.

Chapter 1, The Technical Design Process

QUESTION 10You are a VMware consultant who has been hired to take over a mismanaged VMware vSphere 5 platformestate. You are presented with the vCenter administrator password and given the following information.

The system has full production support from VMware.

The platform has been suffering from performance problems for two weeks.

No documentation exists.

Your role is to design and implement a platform that meets the following requirements:

- R001: Stable for current workloads- R002: Supportable by operations staff

The performance problem mentioned in the initial project information can be classified as:

A. A constraintB. An assumption


Explanation/Reference:Explanation:An assumption is an item which could more than likely impact your design. It is good to ensure that the projecttime and wider business are aware of these assumptions, and that they are agreed upon and validated as partof the design consideration process.

QUESTION 11A project requirement must always be met.

A. TrueB. False


Explanation/Reference:Explanation:A requirement is a definable and measurable project item. It must be part of the delivery, and its removalcannot be justified.

QUESTION 12A current state analysis is a project phase that is carried out to validate the end of a project.

A. TrueB. False


Explanation/Reference:Explanation:A current state analysis gives an architect a way to examine the road ahead. Any oversights at this stage couldhave major implications for the project later on. By ensuring that the current state analysis is completedthoroughly, you can prevent many potential problems.

QUESTION 13The difference between the beginning of a project and the vision is also known as the ____________.

A. current state analysisB. gap state analysisC. upstream relationshipD. downstream relationship


Explanation/Reference:Explanation:By reviewing the current configuration of a system and mapping the final status of components as described inthe vision, the business identifies the gap between the two. A gap state analysis is a review of the items ortasks that are required to progress between the stages. Such an analysis is useful in creating milestone plans,implementation orders, and so on.

QUESTION 14An upstream relationship is a logical object or component that has dependency on other items in a solution.

A. TrueB. False


Explanation/Reference:Explanation:In an upstream relationship, a logical object or component has a dependency on other items in the solution. Forexample, a service running on an application server requires an Active Directory user account to beauthenticated. The application service must be started after the Active Directory service. Therefore, theapplication server has an upstream relationship with the Active Directory service.In a downstream relationship, a logical object or component does not have a dependency on other items in thesolution. For example, say that a multisite web server crashes. The web tier hosting multiple websites willcrash; however, the downstream objects such as the database server will continue to function. Backendprocesses that are dependent on the downstream objects from the web servers can continue to function.

QUESTION 15A component relationship diagram can be used to establish impact analysis.

A. TrueB. False


Explanation/Reference:Explanation:In an upstream relationship, a logical object or component has a dependency on other items in the solution. Forexample, a service running on an application server requires an Active Directory user account to beauthenticated. The application service must be started after the Active Directory service. Therefore, theapplication server has an upstream relationship with the Active Directory service.

In a downstream relationship, a logical object or component does not have a dependency on other items in thesolution. For example, say that a multisite web server crashes. The web tier hosting multiple websites willcrash; however, the downstream objects such as the database server will continue to function. Backendprocesses that are dependent on the downstream objects from the web servers can continue to function.

QUESTION 16A logical diagram may contain ____________. (Choose two)

A. relationship informationB. Data flow informationC. IP addressesD. vendor information


Explanation/Reference:Explanation:A logical diagram can be used to show service components and how they relate to each other. A logicaldiagram is a high-level diagram that is independent of the hardware used for the solution.

QUESTION 17A project vision _______________.

A. is the required endpoint of a project--the purpose for completing the processB. can be achieved after several iterations of a project life cycleC. both of these are correct


Explanation/Reference:Explanation:The project vision indicates the final state the platform should be in. It is the business-led objective, whichprovides value and incorporates the infrastructure qualities.

QUESTION 18Which of the following is not a vSphere component to consider from a design perspective?

A. Network layer componentB. Security layer componentC. Storage layer componentD. Management layer componentE. Compute layer component


Explanation/Reference:Explanation:From a design perspective, the vSphere platform consists of five components, all of which are highly linked.Good design is needed to aggregate these five components into a stable and scalable platform.

QUESTION 19A vendor-best practice can be used regardless of project requirements.

A. TrueB. False

Correct Answer: B

Section: (none)Explanation

Explanation/Reference:Explanation:A best practice is normally based on experience with a successful implementation. By using theseconfigurations, known issues could possibly be avoided. Best practices should not replace project requirementsbut can be used as a starting point, as long as the project requirements are satisfied.

QUESTION 20You are planning a vSphere 4.1 to 5.0 upgrade. The production datastores are 6 TB. Each datastore consist ofthee extents of 2 TB and is currently 65% full. The operations team would like to keep the system as close tothe current configuration as possible. The upgrade process also requires as little service impact as possible. Inaddition, you wish to use storage I/O control as soon as possible, due to a mission-critical business applicationrequirement. Which of the following would be the correct approach?

A. Create a new VMFS 5 datastore of 6 TBEnable storage I/O controlMigrate the VMs using storage vMotionConfigure storage I/O shares as required

B. Upgrade the VMFS 3 datastoreEnable storage I/O controlConfigure storage I/O shares as required


Explanation/Reference:Explanation:When a datastore with VMFS v3 is upgraded with extents to VMFS v5, the logical attributes and extents are notchanged. Storage I/O control cannot be used with datastores composed of extents.

QUESTION 21A logical diagram does not include ____________.

A. high-level components and how they relate to the solutionB. detailed information regarding the components, such as model of systems, IP addresses, and

configurations


Explanation/Reference:Explanation:A logical diagram can be used to show service components and how they relate to each other. A logicaldiagram is a high-level diagram that is independent of the hardware used for the solution. It shows componentsand relationships. In this example, the diagram would should the number of datastores, size, and logic, such asreplication and other settings.

QUESTION 22Which of the following VMware vSphere functionality can help control real-time storage issues?

A. Storage DRSB. Storage I/O control

Correct Answer: B


Explanation/Reference:Explanation:Storage I/O control can be used to monitor and ensure the amount of I/O at contention time. This is based onreal-time stats and requires a support storage system. Storage DRS uses an average of I/O usage.

QUESTION 23You are working as a platform designer for a large hosting provider. You are considering the scalability of asolution that is projected as 50 hosts and 1,500 virtual machines. A VCSA is a project requirement. Which ofthe following is true?

A. The VCSA will scale to 5 hosts and 50 VMs and thus is a risk to project scalability.B. The VCSA can be configured to use a remote SQL database to meet project scalability.C. The VCSA should be configured to use a remote DB2 or Oracle database.


Explanation/Reference:Explanation:

A VCSA is a premade virtual machine. Due to the size of the system and the local DB2components, the systemis limited in support. However, if you expand the virtual machine resources and deploy a remote database, theVCSA can scale out to the vCenter standard limitations.

QUESTION 24A host has four dual-port network cards. What is the maximum number of vSwitches that can be integrated withthe physical network, assuming that network redundancy is not a requirement?

A. 8B. 4C. 64D. 512


Explanation/Reference:Explanation:An ESXi physical NIC can be assigned to only one vSwitch at a time. For example, a host with five NICs canhave a maximum of five vSwitches that can link to the outside world.

QUESTION 25How do you understand and predict the resources available for VMware HA to meet specific projectrequirements?

A. Configure the appropriate admission control policyB. Disable admission control policy


Explanation/Reference:Explanation:An admission control policy tells VMware HA how to calculate the resources it needs to reserve for a cluster. Ituses a combination of memory and CPU reservation configuration or, if no configuration exists, a default lowreservation.

QUESTION 26The admission control policy "Host failure the cluster tolerates" calculates slot size using the combination of the______________.

A. largest reservation for memory and CPU in the clusterB. average usages of memory and CPU in the cluster



QUESTION 27You are considering the use of the VCSA. Which of the following use cases would invalidate VCSA as a designchoice?

A. VMware View Composer linked clonesB. Auto DeployC. Use of sys prep and virtual guest templateD. vCenter linked mode

Correct Answer: DSection: (none)Explanation

Explanation/Reference:Explanation:The simplicity of VCSA makes it a compelling design choice for deployments. However, items that are notsupported--such as linked mode are showstoppers if they are declared project requirements.

VMware View linked clones were not supported prior to v5.0

QUESTION 28If the event of a vCenter failure, which of the following is not true?

A. VMware vMotion is not possible.B. DRS functionality is lost.C. Auto deployment of existing ESXi hosts is impossible.


Explanation/Reference:Explanation:The Auto Deploy feature requires the vCenter for the original deployment and configuration. Following the first

boot, unless a change has been added in the Auto Deploy rules, the subsequent reboots have a dependencyon the Auto Deploy server, not the vCenter.

QUESTION 29Network vMotion requires ______________.

A. network I/O controlB. distributed switchesC. a Vmkernel port marked as Network vMotion


Explanation/Reference:vSphere vMotion Networking Requirements

Migration with vMotion requires correctly configured network interfaces on source and target hosts.Configure each host with at least one vMotion network interface. To ensure secure data transfer, the vMotionnetwork must be a secure network, accessible only to trusted parties. Because vMotion performance improvessignificantly with additional bandwidth, dedicate at minimum a physical 1 Gigabit Ethernet (GigE) NIC tovMotion. As a best practice, provision at least one additional physical NIC as a failover NIC.To determine the maximum number of concurrent vMotions possible, see the Concurrent migration limits atLimits on Simultaneous Migrations in the vSphere Web Client. These limits vary with a host's link speed to thevMotion network.Some configurations include Metro vMotion, which is a feature that enables reliable migrations between hoststhat are separated by high network round-trip latency times. Metro vMotion is enabled when the appropriatelicense is installed. No user configuration is necessary.You can configure multiple NICs for vMotion by adding two or more NICs to the required standard switch. Fordetails, see the VMware knowledge base article at http://kb.vmware.com/kb/2007467.Recommended networking best practices are as follows:■ Use one dedicated GigE adapter for vMotion.■ If only two Ethernet adapters are available:■ For best security, dedicate the GigE adapter to vMotion, and use VLANs to divide the virtual machine andmanagement traffic on the other adapter.■ For best availability, combine both adapters into a bond, and use VLANs to divide traffic into networks: one ormore for virtual machine traffic and one for vMotion.

Configure the virtual networks on vMotion enabled hosts as follows:■ On each host, configure a VMkernel port group for vMotion. <-----■ Ensure that virtual machines have access to the same subnets on source and destination hosts.■ If you are using standard switches for networking, ensure that the network labels used for virtual machine portgroups are consistent across hosts. During a migration with vMotion, vCenter Server assigns virtual machinesto port groups based on matching network labels.

NoteYou cannot migrate virtual machines that are attached to a virtual intranet with vMotion, even if the destinationhost has a virtual intranet configured with the same network label.■ If you are using vSphere Distributed Switches for networking, ensure that source and destination hosts aremembers of all vSphere Distributed Switches that virtual machines use for networking.■ Use of Jumbo Frames is recommended for best vMotion performance.

QUESTION 30VMware HA can protect application corruption issues by using VM monitoring functionality.

A. TrueB. False


Explanation/Reference:Explanation:VM monitoring is the function whereby a virtual machine is restarted when the virtual machine heartbeat hasstopped (such as with a blue screen of death on a Windows machine). The machine is simply restarted on thesame host (that is, not migrated). However, the system would lose data from the point of corruption.

QUESTION 31During a vCenter outage caused by a host power issue, a member of the operations team created anemergency guest VM by connecting directly to one of the hosts. The cluster was enabled for VMware HA at thetime of the vCenter outage. In the event of further problems in the datacenter, is the newly created VMprotected by HA?

A. YesB. No


Explanation/Reference:Explanation:The vCenter manages the update of the VMware HA protected list. When you add a machine while the vCenteris out of service, the list will not be updated.

QUESTION 32When designing a system for VMware HA functionality, which of the following considerations is not an impact tothe design?

A. The size of the hostB. The number of hostsC. Application compatibility with VMware platforms using HA


Explanation/Reference:Explanation:The simplicity of VMware HA is one of the many design benefits. If an application or guest virtual machine isrunning on a vSphere platform, the system is compatible from a high level with VMware HA. It is purely anautomated restart from a functionality perspective.

QUESTION 33VMware fault tolerance requires a cluster-aware application within the guest workload.

A. TrueB. False


Explanation/Reference:

Explanation:VMware fault tolerance, subject to its requirements, can add redundancy without affecting the applicationconfiguration. The guest workload can be a single-instance item.

QUESTION 34The method of guest VM backup can have an effect on the size of datastores used in a vSphere platform.

A. TrueB. False


Explanation/Reference:Explanation:The RTO and RPO requirements and available hardware used in a solution can impact the size of datastoresby limiting the amount of data that can be practically restored. This amount of data is the max size of thedatastore.

QUESTION 35From an operations management perspective, a design should not plan to use a virtual vCenter in a fullyautomated DRS cluster.

A. TrueB. False


Explanation/Reference:Explanation:There are no reason a virtual vCenter should not be used from an operations management perspective. Thereshould, however, be a process for managing the handling of a virtual vCenter outage (for example, DRS VM-to-host affinity rules and lockdown mode behavior).

QUESTION 36You have been sent a query regarding a platform you have just designed and implemented. Following amaintenance window where VMware HA was disabled, the VMware HA settings were lost. How would youprevent this issue?

A. Back up the vCenter database and restore it if the problem reoccurs.B. Instruct the team to use the Host monitoring tab functionality.C. Instruct the team to use the VM monitoring tab functionality.


Explanation/Reference:Explanation:Disabling the vSphere HS cluster settings will change the entire configuration of the cluster from the HSperspective. If the Host Monitoring checkbox is selected, it will allow the configuration to remain; however, theisolation response or outage response will not occur.

QUESTION 37

VMware HA in vSphere 5.0 cannot survive more than five primary host failures. Thus, hosts should bephysically placed in different racks, where possible, to avoid substantial impact.

A. TrueB. False


Explanation/Reference:Explanation:This was true for VMware HA solutions prior to version 5. vSphere 5 can withstand multiple failures and uses amaster/slave topology with a reelection process.

QUESTION 38A guest VM has an 8 GB allocated to it. What is the size of the swap file?

A. 8 GB minus the reservationB. It depends on the limit configuration.C. 8 GB


Explanation/Reference:Explanation:The size of the swap space is the maximum amount of allocated memory that could be reallocated to anotherVM in the event of contention. This is expressed as the size of configured memory minus the reservation.

QUESTION 39Which of the following settings could be utilized when performing a performance test on an application server?

A. CPU LimitsB. Share ValuesC. Reservations


Explanation/Reference:Explanation:To accurately understand the resource allocation, and compare against other tests in a virtual or physicalplatform, an administrator can guarantee resources.

QUESTION 40How many vApps can a guest virtual machine be placed into?

A. 1B. 64C. 8D. 12

Correct Answer: A


Explanation/Reference:Explanation:A vApp is a logical container of guest virtual machine objects. The use of a container provides the ability to usekey management functionality, which can dramatically help a virtualized platform. Automation allows lots of VMsto be managed by fewer staff. Although vApps can be nested, a single virtual machine can be defined in onlyone vApp.

QUESTION 41VMware HA respects vApp startup order.

A. TrueB. False


Explanation/Reference:Explanation:A vApp is a logical container of guest virtual machine objects. The use of a container provides the ability to usekey management functionality, which can dramatically help a virtualized platform. Automation allows lots of VMsto be managed by fewer staff. Although the objects have startup and shutdown automation features, VMwareHA does not currently understand this feature; therefore, at present, a manual process should be used torestart applications in the event of a VMware HA event.

QUESTION 42vApp startup order can be configured to work with VMware Heartbeat status.

A. TrueB. False


Explanation/Reference:Explanation:A vApp is a logical container of guest virtual machine objects. The use of a container provides the ability to usekey management functionality, which can dramatically help a virtualized platform. Automation allows lots of VMsto be managed by fewer staff. The virtual machine Heartbeat is part of the VMware tools service. Otherapplication services can be made a high priority or a parent of the VMware Tools service; in this case, onstartup, waiting for the VMware tools service to start before starting the next guest virtual machine in the vAppwould assume that the application service has started successfully.

QUESTION 43A vApp can be created with its own resource settings and requirements.

A. TrueB. False



Explanation:A vApp is a logical container of guest virtual machine objects. The use of a container provides the ability to usekey management functionality, which can dramatically help a virtualized platform. Automation allows lots of VMsto be managed by fewer staff. A vApp can have resource allocations applied at the vApp level, outside theresource pool configuration.

QUESTION 44Which of the following is true?

A. An OVF export of a custom vApp consists of multiple files.B. An OVF export of a customer vApp consists of a single OVA file.


Explanation/Reference:Explanation:OVF (Open Virtualization Format) files are prepackaged virtual machines that can be created with attributessuch as EULA, IP settings, and so on. They can be imported into most modern virtualization hypervisors, notjust VMware, thus enabling businesses to deploy and share applications simply by importing and exporting files,as opposed to going through a long, complicated installation process.

The OVF export consists of several files placed in one directory, while an OVA file is the same logical productbut exists as a single file.

QUESTION 45A guest VM has 50 GB allocated to it and a 2 GB limit. What is the size of the swap file?

A. 50 GB minus the reservationB. 48 GB minus the reservationC. 52 GB minus the reservationD. 2 GB minus the reservation


Explanation/Reference:Explanation:The size of the swap space is the maximum amount of allocated memory that could be reallocated to anotherVM in the event of contention. This is expressed as the size of configured memory minus the reservation.

QUESTION 46You are working on a virtual guest design for the deployment of a critical business application. The softwarevendor has provided you with some projected workloads. One of the project requirements is to ensure thatbusiness application performance is guaranteed. Which of the following would be the best approach for guestconfiguration?

A. Configure the virtual guest with a reservation, as specified, as the minimum requirement for the applicationto run.

B. Configure the virtual guest with a reservation, as specified, as the projected initial workload requirement.


Explanation/Reference:Explanation:Allocated resources are shown in the guest operating system and are not guaranteed. The amount depends onthe unreserved resources available at the time. Assuming no functionality issues, you can configure aproduction application to be guaranteed its projected workload, and the system should deliver.Without a reservation, there is potential for a performance impact if there is contention.

QUESTION 47Application performance test cases are most accurate if based on ____________.

A. quantitative success criteriaB. vendor best practices


Explanation/Reference:Explanation:The best validation is to place a platform under a typical test of what it will be faced with in the field--forexample, having a simulated number of users go through a workflow (perhaps a website). A lot of these tasksvary with the type of application and are primarily application functionality based. In addition, platform orinfrastructure metrics are key for validation and for information to be used within the operational documentation(for example, troubleshooting guide, monitoring recommendations).

QUESTION 48An installation guide should contain _____________. (Choose two)

A. basic troubleshooting and baseline monitoring for verification purposesB. entry criteria or requirementsC. justifications for design choicesD. best practices.


Explanation/Reference:Explanation:An installation guide provides engineers a detailed reference and process to install and verify a solution. Allrelevant components and processes are detailed. It is also useful to include troubleshooting or known issues, ifany were experienced during the development and test phases.

QUESTION 49An implementation plan should contain _____________.

A. a milestone planB. risks, assumptions, and dependencies on the activities in the implementation planC. order


Explanation/Reference:Explanation:An implementation plan gives all members of a project team a level of understanding of the technical approach

of a project, the number of phases, major tasks in each phase, and the correct order for completing the tasks.

QUESTION 50You are a VMware consultant for a large enterprise running VMware vSphere 4.1. You are reviewing theupgrade documentation created to take the company to version 5.X of the software. The upgrade has severalrequirements, including the following:

- Minimize the impact to the business applications- Do a full rollback, if required, for any issues not foreseen by the project team

You notice in the documentation that the upgrade to VMFS 5 is mentioned as being non-disruptive and havingzero impact on the technical solution. Is this technically correct?

A. YesB. No


Explanation/Reference:Explanation:In this example, a VMFS 5 upgrade cannot be rolled back without extra scratch space and without usingstorage vMotion. These things could add extra I/O load on the systems and affect the first requirement.

QUESTION 51During an upgrade of VMware vSphere 4.1 to vSphere 5.0, several virtual machines appeared to have lostnetwork configuration. What is the possible cause of the issue?

A. DHCP server not availableB. Incorrect order of upgrade implementation stepsC. Incorrect drivers.


Explanation/Reference:Explanation:This can be experienced when migrating from a virtual machine hardware level and have an old version ofVMware tools installed. The guest operating system may not understand the hardware and may create or loseinformation such as the MAC address and network settings. By upgrading VMware tools first and thenupgrading the hardware the correct drivers and software are present for a non-impacting upgrade.

QUESTION 52An implementation plan is a set of instruction that provide sufficient detail for an engineer to configure or installa platform according to a physical design.

A. TrueB. False



An implementation plan gives all members of a project team a level of understanding of the technical approachof a project, the number of phases, the major tasks in each phase, and the correct order for completing thetasks. This documentation can be used to bring in skilled people and to judge the project stability and progressthroughout the implementation. The plan should be detailed enough for technical personnel to understand thetasks being completed but without detailing specific configuration and installation processes.

QUESTION 53A validation plan is a set of processes which prove that a project or a function of a platform has beenconfigured correctly and behaves as designed.

A. TrueB. False


Explanation/Reference:Explanation:A validation plan can range from a detailed test plan to high-level statements. It should not be subjective. Thebest validation is to place a platform under a typical test of what it will be faced with in the field--for example,having a simulated number of users go through a workflow (perhaps a website). A lot of these tasks vary withthe type of application and are primarily application functionality based. In addition, platform or infrastructuremetrics are key for validation and for information to be used within the operational documentation (for example,troubleshooting guide, monitoring recommendations).

QUESTION 54A validation plan can be used to gather further requirements.

A. TrueB. False



QUESTION 55A platform validation plan is primarily concerned with guest VM settings and application delivery rather thanVMware platform functionality.

A. TrueB. False



A validation plan can range from a detailed test plan to high-level statements. It should not be subjective. Thebest validation is to place a platform under a typical test of what it will be faced with in the field--for example,having a simulated number of users go through a workflow (perhaps a website). A lot of these tasks vary withthe type of application and are primarily application functionality based. In addition, platform or infrastructuremetrics are key for validation and for information to be used within the operational documentation (for example,troubleshooting guide, monitoring recommendations).

QUESTION 56For effective VMware platform validation to take place, that platform should be _____________.

A. running test guest workloadsB. running workloads of projected application resource requirementsC. stress tested until failure to understand capacity



QUESTION 57A good design ______________. (Choose two)

A. meets project requirements and considers infrastructure qualitiesB. uses the latest best practices and considers infrastructure qualitiesC. removes all single points of failureD. considers the impact of component failure and subsequent mitigation

Correct Answer: ADSection: (none)Explanation

Explanation/Reference:Explanation:Good design should meet the project requirements and consider the properties of assumed platform design.Protecting data requires that a system be available and manageable, that it have good performance, and that itbe easy to recover and be secure.

QUESTION 58Vendor support may prevent an application from being virtualized.

A. TrueB. False



Good design should meet the project requirements and consider the properties of assumed platform design.Protecting data requires that a system be available and manageable, that it have good performance, and that itbe easy to recover and be secure.

Explanation

Explanation/Reference:Explanation:DRS is controlled by the vCenter. vCenter invokes vMotion based on metrics. During the period where thevCenter is out of action, DRS is not functional.

QUESTION 68You are reviewing a vSphere platform design. The system is planning to use a virtual vCenter server. Which ofthe following is true if the vCenter fails when using this design?

A. DRS is unaffected.B. VMware HA can protect and restart the vCenter.C. The VCSA cannot be used.D. vCenter must be configured in Linked mode.


Explanation/Reference:Explanation:DRS is controlled by the vCenter. vCenter invokes vMotion based on metrics. During the period where thevCenter is out of action, DRS is not functional. VMware HA can mitigate against issues by restarting thevCenter in the event of an outage.

QUESTION 69Which of the following is a logical boundary for vMotion?

A. ClusterB. vDCC. FolderD. Resource Pool


Explanation/Reference:Explanation:By design, vMotion is possible from a logical perspective between the vDC. It is possible, however, to have astretched cluster and to not satisfy vMotion requirements. The logical boundary is limited to vDCs.

QUESTION 70You have been asked to design a system with the following VMware functionality enabled:- R001: VMware HA must be functional.- R002: VMware SRM can be used between two sites for DR processes.- R003: You must be able to see all hosts from a single pane of glass.

From these requirements:

A. A vSphere 5.0 VCSA can provide an acceptable solution.B. A vSphere 5.0 Windows-based vCenter can provide an acceptable solution.C. The requirements cannot be met.

Correct Answer: B


Explanation/Reference:Explanation:The VCSA can function with VMware SRM. However, for SRM functionality, both sites require a vCenterinstallation. This would limit the choice of single-glass-pane management to Linked mode. A Linked modeinstallation requires Microsoft technology in the ADAM instance, and thus eliminates the VCSA choice.

QUESTION 71When using VMware HA, the larger the consolidation ratio, the smaller the potential impact to the business inthe event of a VMware HA event.

A. TrueB. False


Explanation/Reference:Explanation:VMware HA can satisfy the majority of RTO scenarios. In general, businesses can tolerate small outages ofshorter than a few minutes. Designed correctly, HA can satisfy this requirement while providing hardware-levelprotection. Some design considerations are the restart time and impact of the outage; the fact that the moreVMs per host, the higher the consolidation ratio; and the possibly longer time to restart along with its largerimpact to the business.

QUESTION 72In a platform with two vCenters configured with Linked mode, one vCenter can be configured using the VCSA.

A. TrueB. False


Explanation/Reference:Explanation:A Linked mode installation requires Microsoft technology in the ADAM instance, and thus eliminates the VCSAchoice.

QUESTION 73When considering scalability, the VCSA is not as effective as the vCenter installed on a Windows platform.

A. TrueB. False


Explanation/Reference:Explanation:The VCSA can scale to the same size of the Windows-based platform when using a remote database based onOracle or DB2. Microsoft SQL, however, is not supported. The built-in database is a DB2version, which is onlysupported for small platforms.

QUESTION 74When deploying a vCenter solution for a vSphere design, continuous uptime is stated as a requirement.

The use of vCenter heartbeat has been agreed upon and budgeted. The design consists of two VCSAs.

A. TrueB. False

QUESTION 106An active passive storage array should be configured with the fixed multipathing policy.

A. TrueB. False


Explanation/Reference:Explanation:An active passive array will have only one active path at a time. An array like this should be configured with theMRU multipathing policy. An active-active array has multiple active paths and should be configured with round-robin or fixed-multipathing policies.

QUESTION 107What multipathing options can be configured with an active-active array? (Choose two)

A. FixedB. MRUC. SATPD. Round-robin

Correct Answer: ADSection: (none)Explanation


Active/Active

Fixed (Fixed): Uses the designated preferred path flag, if it has been configured. Otherwise, it uses the firstworking path discovered at system boot time. If the ESXi/ESX host cannot use the preferred path or it becomesunavailable, the ESXi/ESX host selects an alternative available path. The host automatically returns to thepreviously-defined preferred path as soon as it becomes available again. This is the default policy for LUNspresented from an Active/Active storage array.

Round Robin (RR): Uses an automatic path selection rotating through all available paths, enabling thedistribution of load across the configured paths.

For Active/Passive storage arrays, only the paths to the active controller will be used in the Round Robinpolicy.For Active/Active storage arrays, all paths will be used in the Round Robin policy.

Active/Passive

Most Recently Used (MRU): Selects the first working path, discovered at system boot time. If this pathbecomes unavailable, the ESXi/ESX host switches to an alternative path and continues to use the new pathwhile it is available. This is the default policy for Logical Unit Numbers (LUNs) presented from an Active/Passive array. ESXi/ESX does not return to the previous path if, or when, it returns; it remains on the workingpath until it, for any reason, fails.

QUESTION 138A design calls for 10 virtual machines, each with 2 GB of RAM, to be located on a single VMFS datastore. Only5 virtual machines will be powered on at one time. If the virtual machines are using default resource settings,how much space on the datastore will be utilized by swap files?

A. 20 GBB. 10 GBC. No swap files will be created.D. None of the above


Explanation/Reference:Explanation:By default, the swap file is the same size as the available memory of a VM. The swap file is created when youpower on a virtual machine and removed when you power it off. With 5 virtual machines powered on and witheach virtual machine having an available memory setting of 2 GB, 10 GB of space will be used for the swapfiles.

QUESTION 139You have a requirement to create a three-tiered application as part of a virtual machine's design.

QUESTION 140You have been tasked with creating a new domain controller in the vSphere environment to replace thephysical domain controller. You are trying to determine how much memory to give the virtual machine. What isyour best option?

A. Create the VM to match the memory of the domain controllerB. Give the VM as much memory as possible to ensure optimal performance

C. Read the vendor documentation and base your memory setting on thatD. Look at the long-term memory metrics of the server and have the memory setting match the maximum

memory used by the domain controller


Explanation/Reference:Explanation:Viewing the memory performance data of the physical host can give you a solid understanding of how memoryis used on the host and gives a good indication of the amount of memory you should set up for the replacementvirtual machine.

QUESTION 141It is a best practice to give a virtual machine a single virtual CPU unless there is a compelling reason to give avirtual machine more than one virtual CPU.

A. TrueB. False


Explanation/Reference:Explanation:A majority of your virtual machines can run with a single vCPU. Unless the application specifically requiresmultiple vCPUs, try to start with one.

QUESTION 142When is it appropriate for a virtual machine to use the virtual machine swap file?

A. AlwaysB. NeverC. When you're trying to save memoryD. When the swap file is on fast storage


Explanation/Reference:Explanation:A virtual machine using the swap file as memory is usually an indication that there is not enough memory on theESXi host to provide memory resources to all the virtual machines on the host. Steps should be taken toalleviate the problem.

QUESTION 143The swap file must always be stored with the other virtual machine files.

A. TrueB. False

Correct Answer: BSection: (none)

Explanation

Explanation/Reference:Explanation:A virtual machine's swap file can be stored separately on a local or shared datastore. This is a good option ifyou are replicating storage to another location and do not wish to replicate files that are not needed at thereplicated site.

QUESTION 144Part of your design includes updating VMware tools and virtual hardware to a newly updated vSphere 5.1architecture. What is the best method for updating tools and hardware?

A. Manually update each virtual machineB. Don't bother updating the VMs; the new version of hardware and tools are not necessaryC. Use Update Manager to update all the virtual machines at onceD. Use Update Manager to help update the virtual machines in groups, as maintenance windows allow


Explanation/Reference:Explanation:Using Update Manager is the best way to upgrade multiple virtual machines in an automated fashion. Youwould not want to update them all at once because it would be time- consuming and would require a lot ofresources and lots of reboots. As a result, there might not be enough time to finish within a maintenancewindow.

QUESTION 145Which of the following is a good way to set a memory reservation?

A. Use reservations on all virtual machines to ensure that they are all guaranteed memory.B. Set a reservation to a virtual machine's available memory to avoid creating a swap file.C. Never set a reservation on a virtual machine.D. Set a reservation only on a critical virtual machine, with the reservation set to the minimum amount of

memory needed for acceptable performance.


Explanation/Reference:Explanation:Setting reservations should be the exception and not the rule. The reservation should be set to the minimumamount required for acceptable performance.

QUESTION 146While viewing the ESXi host resource tab, you notice that you have 1 GB of available memory. You attempt toturn on a virtual machine with a 1 GB reservation, and the virtual machine will not power on. What is preventingthe virtual machine from powering on?

A. There are too many virtual machines on the host.B. For a virtual machine to start, there must be enough available memory for the reservation and memory

overhead.C. A reservation was set too high.D. A CPU reservation was not set.


Explanation/Reference:Explanation:All virtual machines require some memory to use as overhead to handle virtualization. Even if a virtual machinedid not have a reservation, real memory would still be required for the overhead.

QUESTION 147Which type of virtual disk takes the longest to create but performs the best?

A. Thin provisionedB. Eager-zeroC. Lazy-zeroD. Flat


Explanation/Reference:Explanation:An eager-zero disk allocates and zeroes out all the block at once. While this type of disk takes significantlylonger to create, the disk performs better than the others because the other disks require the block to be zeroedout before writing to the block. Since the blocks have already been zeroed with eager-zero, that is notnecessary.

QUESTION 148All virtual machine files should always be on the same datastore.

A. TrueB. False


Explanation/Reference:Explanation:Some applications require different types of performance on the multiple disks they require. If this is the case, itis acceptable to put virtual disks on two different datastores that have different performance and RAID features.

QUESTION 149Which metric displays the amount of time, in milliseconds, it takes for a virtual CPU to get processing time on aphysical CPU?

A. CPU WaitB. BallooningC. CPU ReadyD. pCPU

QUESTION 178You are a VMware architect employed to design and build application environments and the underlying platformfor a software development company. The company is using a "dev-ops" approach and has engaged with youat the beginning of the first planning meeting/pre-sprint.The software has yet to be written. However, you have some high-level specifications that are subject tochange at each of the early meetings.

The ______ is more logical for virtual machine sizing.

A. predictive sizing approach based on current softwareB. adaptive sizing approach

Correct Answer: BSection: Predictive/AdaptiveExplanation

Explanation/Reference:Explanation:There are two types of scaling approaches in virtual platforms: adaptive and predictive. Both approaches areusable; however, a designer must work out which is the best approach for each project.

The adaptive approach to guest virtual machine design is a major advantage that virtualization technologybrings to a datacenter. It allows a guest virtual machine to be created initially on a few metrics or high-levelrequirements (such as a limited budget) and scaled (that is, grown, not shrunk) through the virtual machinelifecycle. In many cases, this scaling can be performed hot/live without outage/downtime to the runningapplications.

The predictive approach, on the other hand, requires more planning and research, and you must know themetrics before deployment. The advantage here is that once the virtual machine has been deployed, onlyapplication maintenance is required. The application requirements are known.

QUESTION 209Before the implementation phase of a project, all design choices should be ______________.

A. validated and justified to the business and project team membersB. documented, validated, and verified as vendor-based best practicesC. validated

Correct Answer: ASection: Design Phases & QualitiesExplanation

Explanation/Reference:Explanation:The best validation is to place a platform under a typical test of what it will be faced with in the field--forexample, having a simulated number of users go through a workflow (perhaps a website). A lot of these tasksvary with the type of application and are primarily application functionality based. In addition, platform orinfrastructure metrics are key for validation and for information to be used within the operational documentation(for example, troubleshooting guide, monitoring recommendations).

QUESTION 210When designing a storage platform, which of the following should be considered as part of the overall design?

A. CapacityB. I/O requirements of the applications to be supportedC. Disk latency toleranceD. Growth rateE. All of the above

Correct Answer: ESection: StorageExplanation

Explanation/Reference:Explanation:A storage platform logical design requires in-depth analysis of factors that can affect applications. In the case ofstorage, aspects that relate to the physical layer--such as the amount of usable space required for services; thesize, number, and speed of disks; and how fast the data is being produced--could have a substantial impact tothe storage platform.

QUESTION 211Storage DRS can be enabled and can balance I/O levels based on _______________

A. real-time statsB. historical stats

Correct Answer: BSection: StorageExplanation

Explanation/Reference:Explanation:Storage DRS can balance I/O by using storage vMotion. This would be based on historical values for a periodof time. Storage DRS would make decisions based on these figures. If the system were using real-time stats,the machines could potentially migrate a lot more. This could have an effect on the latency figures for somesystems. The larger historical sampling in storage DRS allows the system to make a decision with limited risk ofimpacting I/O--unlike moving a virtual machine over and over again.

QUESTION 214A project vision in some cases may not be achieved due to constraints, risks, and other project factors.However, a project vision is required to guide a project throughout the life cycle.

A. TrueB. False

Correct Answer: ASection: Project FactorsExplanation

Explanation/Reference:Explanation:The technical design process enables a platform designer to work in a methodical way and with others whohave similar objectives. The vision is the endpoint--the environment or situation whereby the business wouldideally like to be following the process.

QUESTION 215VMware HA can reduce the requirement for disaster recovery planning and documentation.

A. TrueB. False

Correct Answer: BSection: High AvailabilityExplanation

Explanation/Reference:Explanation:VMware HA can satisfy the majority of RTO scenarios. In general, a business can tolerate small outages of lessthan a few minutes. When designed correctly, HA can satisfy this requirement while providing hardware-levelprotection. Chapter 4, The Importance of vMotion, VMware HA, and Fault Tolerance

QUESTION 216You have been asked to review a vSphere HA design. The admission control policy is set to "The number ofhost failures tolerated." The virtual machines vary in size, and use of VM-based reservations is common. Whichof the following should be recommended? (Choose three)

A. The platform has reservations removed unless specifically required by an application vendor verified orworkload verified requirement.

B. The platform should be configured with reservations based on resource poolsC. The platform should be configured with an appropriate slot size or the admission control policy changed to a

percentage based policy.D. The platform should not be configured with reservations based on resource pools

Correct Answer: ABCSection: High AvailabilityExplanation



QUESTION 217Only a software vendor develops a standard process or configuration.

A. TrueB. False

Correct Answer: BSection: Best PracticesExplanation

Explanation/Reference:Explanation:A best practice is based on experience with delivering a solution. A new product will have limited best-practiceinformation except for vendor- or vendor-partner-based recommendations. The longer a technology is used in acommunity, the more potential success; therefore, best practices may be recommended by non-vendor-relatedpeople. It is up to a designer to validate this information rather than ignore it straightaway.

QUESTION 218Based on the information in the high-level design extract, what storage protocol is unsuitable?

Case Study Title (Case Study):You are the technical designer for a vSphere platform transformation project. After conducting SME interviewsand using various platform information-gathering methods, you have created a high-level design document.

This document specifies the following:

Requirements:

R1. The solution must not have a single point of failure.R2. Production applications must not have an outage of more than 10 seconds.R3. Data must be based in the UK.R4. There is a 7-year retention policy for contracts.R5. Applications should support existing and developing workloads for the next 3 years' growth.

Spec of servers:

Web 1 vCPU, 2 GB RAM, 100 GB storageApp 1 vCPU, 4 GB RAM, 100 GB storageDB 2 vCPU, 16 GB RAM, 750 GB storage

A. NFSB. iSCSIC. FC


Explanation/Reference:Explanation:If you limit the application traffic to a specific dedicated network (that is, a separate VLAN) and using enforcedDRS affinity rules, the application traffic will not traverse the ESXi host's physical network interfaces. This willensure that the impact of the application is minimized, while also ensuring that the application itself is notlimited. The application servers already have vCPU settings. This suggests that the system has already beingvirtualized in both types of environments. Network I/O control could be useful in the event of contention, but therole of a designer would be to plan to prevent contention where possible; other options would be morebeneficial. In addition, Requirement 5 specifies that the system should work with workloads over the next3years. Network I/O control would suggest contention very early in the platform history.
