Exam A

QUESTION 1What is the acceptable amount of one-way network delay for voice and video applications?

A. 300 bytesB. 1 secC. 150 msD. 500 ms

Correct Answer: CSection: Describe the Methodology used to design a networkExplanation

Explanation/Reference:Explanation:

Delay Components in VoIP NetworksThe ITU's G.I 14 recommendation specifics that the one-way delay between endpoints should not exceed 150 ms to be acceptable, commercial voice quality. Inprivate networks, somewhat longer delays might be acceptable for economic reasons. The ITU G.114 recommendation specifics that 151- ms to 400-ms one-waydelay might be acceptable provided that organizations are aware that the transmission time will affect the quality of user applications. One-way delays of above 400ms are unacceptable for general network planning purposes.

QUESTION 2Which mode is used to exclusively look for unauthorized access points?

A. monitor modeB. sniffer modeC. rogue detector modeD. local mode




Interference detection and avoidance: As Cisco LWAPs monitor all channels, interference is detected by a predefined threshold (10 percent by default). Interferencecan be generated by rogue APs, microwaves, cordless telephones, Bluetooth devices, neighboring WLANs, or other electronic devices.

QUESTION 7Which one of these statements is an example of how trust and identity management solutions should be deployed in the enterprise campus network?

A. Authentication validation should be deployed as close to the data center as possible.B. Use the principle of top-down privilege, which means that each subject should have the privileges that are necessary to perform their defined tasks, as well as

all the tasks for those roles below them.C. Mixed ACL rules, using combinations of specific sources and destinations, should be applied as close to the source as possible.D. For ease of management, practice defense in isolation - security mechanisms should be in place one time, in one place.


Explanation/Reference:Explanation:Validating user authentication should be implemented as close to the source as possible, with an emphasis on strong authentication for access from untrustednetworks. Access rules should enforce policy deployed throughout the network with the following guidelines:·Source-specific rules with any type destinations should be applied as close to the source as possible. ·Destination-specific rules with any type sources should beapplied as close to the destination as possible.·Mixed rules integrating both source and destination should be used as close to the source as possible.

An integral part of identity and access control deployments is to allow only the necessary access. Highly distributed rules allow for greater granularity and scalabilitybut, unfortunately, increase the management complexity. On the other hand, centralized rule deployment eases management but lacks flexibility and scalability.

Practicing "defense in depth" by using security mechanisms that back each other up is an important concept to understand. For example, the perimeter Internetrouters should use ACLs to filter packets in addition to the firewall inspecting packets at a deeper level.

QUESTION 8With deterministic Wireless LAN Controller redundancy design, the different options available to the designer have their own strengths. Which one of thesestatements is an example of such a strength?

A. Dynamic load balancing, or salt-and-pepper access point design, avoids the potential impact of oversubscription on aggregate network performance.B. N+N redundancy configuration allows logically grouping access points on controllers to minimize intercontroller roaming events.


C. N+N+1 redundancy configuration has the least impact to system management because all of the controllers are colocated in an NOC or data center.D. N+1 redundancy configuration uses Layer 3 intercontroller roaming, maintaining traffic on the same subnet for more efficiency.


Explanation/Reference:Explanation:With such an arrangement there is no complex mesh of access points & controllers. Link: http://www.cisco.com/web/learning/le31/le46/cln/qlm/CCDA/design/understanding-wireless- network-controller-technology-3/player.html

N+N WLC RedundancyWith N+N redundancy, shown in Figure 5-14. an equal number of controllers hack up each other. For example, a pair of WLCs on one floor serves as a backup to asecond pair on another floor. The top WLC is primary for API and AP2 and secondary for AP3 and AP4. The bottom WLC is primary for AP3 and AP4 andsecondary for API and AP2. There should be enough capacity on each controller to manage a failover situation.

N+N+1 WLC RedundancyWith N+N+1 redundancy, shown in Figure 5-15, an equal number of controllers back up each other (as with N+N), plus a backup WLC is configured as the tertiaryWLC for the APs. N+N+1 redundancy functions the same as N+N redundancy plus a tertiary controller that backs up the secondary controllers. The tertiary WLC isplaced in the data center or network operations center


QUESTION 9You have a campus network that consists of only Cisco devices. You have been tasked to discover the device platforms, the IOS versions, and an IP address ofeach device to map the network. Which proprietary protocol will assist you with this task?

QUESTION 11WAN backup over the Internet is often used to provide primary connection redundancy. Which is the most important consideration when passing corporate traffic


over the public Internet?

A. securityB. static versus dynamic routingC. bandwidthD. QoSE. latency

Correct Answer: ASection: Describe the Methodology used to design a networkExplanation


WAN Backup over the InternetAnother alternative for WAN backup is to use the Internet as the connectivity transport between sites. However, keep in mind that this type of connection does notsupport bandwidth guarantees. The enterprise also needs to work closely with the ISP to set up the tunnels and advertise the company's networks internally so thatremote offices have reachable IP destinations. Security is of great importance when you rely on the Internet for network connectivity, so a secure tunnel using IPsecneeds to be deployed to protect the data during transport.

QUESTION 24Which two of these practices are considered to be best practices when designing the access layer for the enterprise campus? (Choose two.)

A. Implement all of the services (QoS, security, STP, and so on) in the access layer, offloading the work from the distribution and core layers.B. Always use a Spanning Tree Protocol; preferred is Rapid PVST+.C. Use automatic VLAN pruning to prune unused VLANs from trunked interfaces to avoid broadcast propagation.D. Avoid wasted processing by disabling STP where loops are not possible.E. Use VTP transparent mode to decrease the potential for operational error.


Correct Answer: BESection: Design Basic Enterprise Campus NetworksExplanation


When designing the building access layer, you must consider the number of users or ports required to size up the LAN switch. Connectivity speed for each hostshould also be considered. Hosts might be connected using various technologies such as Fast Ethernet, Gigabit Ethernet, or port channels. The planned VLANsenter into the design.

Performance in the access layer is also important. Redundancy and QoS features should be considered. The following are recommended best practices for thebuilding access layer:

· Limit VLANs to a single closet when possible to provide the most deterministic and highly available topology.· Use Rapid Per-VLAN Spanning Tree Plus (RPVST+) if STP is required. It provides the faster convergence than traditional 802.1d default timers.· Set trunks to ON and ON with no-negotiate.· Manually prune unused VLANs to avoid broadcast propagation (commonly done on the distribution switch).· Use VLAN Trunking Protocol (VTP) Transparent mode, because there is little need for a common VLAN database in hierarchical networks.· Disable trunking on host ports, because it is not necessary. Doing so provides more security and speeds up PortFast.· Consider implementing routing in the access layer to provide fast convergence and Layer 3 load balancing.· Use the switchport host commands on server and end-user ports to enable PortFast and disable channeling on these ports.· Use Cisco STP Toolkit, which provides· PortFast: Bypass listening-learning phase for access ports · Loop GuarD. Prevents alternate or root port from becoming designated in absence of bridge protocoldata units (BPDU)· Root GuarD. Prevents external switches from becoming root · BPDU GuarD. Disables PortFast-enabled port if a BPDU is received Cisco Press CCDA 640-864Official Certification Guide Fourth Edition, Chapter 3, Page 85

QUESTION 25Which of these statements is true concerning the data center access layer design?

A. The access layer in the data center is typically built at Layer 3, which allows for better sharing of services across multiple servers.B.

Correct Answer:



Explanation/Reference:Explanation:Network virtualization encompasses logical isolated network segments that share the same physical infrastructure. Each segment operates independently and islogically separate from the other segments. Each network segment appears with its own privacy, security, independent set of policies, QoS levels, and independentrouting paths.

Here are some examples of network virtualization technologies:

Device virtualization allows for a single physical device to act like multiple copies of itself. Device virtualization enables many logical devices to run independently ofeach other on the same physical piece of hardware. The software creates virtual hardware that can function just like the physical network device. Another form ofdevice virtualization entails using multiple physical devices to act as one logical unit.

QUESTION 67Cisco Identity-Based Networking Services relies heavily on the 802.1X protocol. Which other authentication solution is used hand-in-hand with 802.1X toauthenticate users for network access?

A. RADIUSB. LEAPC. IPsecD. TACACSE. ISAKMP



Cisco Identity-Based Network ServicesThe Cisco Identity-Based Network Services solution is a way to authenticate host access based on policy for admission to the network. IBNS supports identityauthentication, dynamic provisioning of VLANs on a per-user basis, guest VLANs, and 802.1X with port security. The 802.1 X protocol is a standards-based protocolfor authenticating network clients by permitting or denying access to the network. The 802.1 X protocol operates between the end-user client seeking access and anEthernet switch or wireless access point (AP) providing the connection to the network. In 802.1 X terminology, clients are called supplicants, and switches and APsare called authenticates. A back-end RADIUS server such as a Cisco Access Control Server (ACS) provides the user account database used to applyauthentication and authorization. With an IBNS solution, the host uses 802.IX and Extensible Authentication Protocol over LANs (EAPoL) to send the credentialsand initiate a session to the network. After the host and switch establish LAN connectivity, username and password credentials are requested. The client host thensends the credentials to the switch, which forwards them to the RADIUS ACS. The RADIUS ACS performs a lookup on the username and password to determinethe credentials' validity. If the username and password are correct, an accept message is sent to the switch or AP to allow access to the client host. If the usernameand password are incorrect, the server sends a message to the switch or AP to block the host port.Figure 13-4 illustrates the communication flow of two hosts using 802.1X and KAPoL with the switch, AP, and back-end RADIUS server.

QUESTION 68Which protocol is used to reserve bandwidth for the transport of a particular application data flow across the network?

+ It improves business agility by establishing business requirements and technology strategies. + It increases network availability by producing a sound networkdesign and validating the network operation.+ It speeds access to applications and services by improving availability, reliability, security, scalability, and performance.+ It lowers the total cost of ownership by validating technology requirements and planning for infrastructure changes and resource requirements.(Reference: Cisco CCDA Official Exam Certification Guide, 3rd Edition) described in the link below. Link: http://www.ciscopress.com/articles/article.asp?p=1608131&seqNum=3

QUESTION 76During which phase of the PPDIOO model would you conduct interviews with supporting staff to develop and propose a viable solution?

A. PrepareB. PlanC. DesignD. ImplementE. OperateF. Optimize




Prepare PhaseThe Prepare phase establishes organization and business requirements, develops a network strategy, and proposes a high-level conceptual architecture to supportthe strategy. Technologies that support the architecture are identified. This phase creates a business case to establish a financial justification for a network strategy.

QUESTION 77Which three are considered as technical constraints when identifying network requirements? (Choose three.)

A. support for legacy applicationsB. bandwidth support for new applicationsC. limited budget allocationD. policy limitationsE. limited support staff to complete assessmentF. support for existing legacy equipmentG. limited timeframe to implement

Correct Answer: ABFSection: Describe the Methodology used to design a networkExplanation


Network design might be constrained by parameters that limit the solution. Legacy applications might still exist that must be supported going forward, and these


applications might require a legacy protocol that may limit a design. Technical constraints include the following:·Existing wiring does not support new technology.·Bandwidth might not support new applications.·The network must support exiting legacy equipment.·Legacy applications must be supported (application compatibility).

QUESTION 78Characterizing an existing network requires gathering as much information about the network as possible. Which of these choices describes the preferred order forthe information-gathering process?

A. site and network audits, traffic analysis, existing documentation and organizational inputB. existing documentation and organizational input, site and network audits, traffic analysisC. traffic analysis, existing documentation and organizational input, site and network auditsD. site and network audits, existing documentation and organizational input, traffic analysis



This section describes the steps necessary to characterize the existing network infrastructure and all sites. This process requires three steps:

Step 1. Gather existing documentation about the network, and query the organization to discover additional information. Organization input, a network audit, andtraffic analysis provide the key information you need. (Note that existing documentation may be inaccurate.) Step 2. Perform a network audit that adds detail to thedescription of the network. If possible, use traffic-analysis information to augment organizational input when you are describing the applications and protocols usedin the network.Step 3. Based on your network characterization, write a summary report that describes the health of the network. With this information, you can propose hardwareand software upgrades to support the network requirements and the organizational requirements.

Section: Describe the Methodology used to design a networkExplanation


Small Branch DesignThe small branch design is recommended for branch offices that do not require hardware redundancy and that have a small user base supporting up to 50 users.This profile consists of an access router providing WAN services and connections for the LAN services.

The Layer 3 WAN services are based on the WAN and Internet deployment model. A T1 is used for the primary link, and an ADSL secondary link is used forbackup. Other network fundamentals are supported, such as EIGRP, floating static routes, and QoS for bandwidth protection.

Medium Branch DesignThe medium branch design is recommended for branch offices of 50 to 100 users, which is similar to the small branch but with an additional access router in theWAN edge (slightly larger) allowing for redundancy services.


Large Branch DesignThe large branch design is the largest of the branch profiles, supporting between 100 and 1000 users. This design profile is similar to the medium branch design inthat it also provides dual access routers in the WAN edge. In addition, dual Adaptive Security Appliances (ASA) are used for stateful firewall filtering, and dualdistribution switches provide the multilayer switching component. The WAN services use an MPLS deployment model with dual WAN links into the WAN cloud.

QUESTION 121AAA Video operates a chain of 50 video rental stores located in the Northwestern United States. They currently have a Point-of-Sale (POS) system in which eachstore posts its daily sales data and inventory changes to a central database through dial-up communication. There is no interaction between the stores and thecentral system during business hours. The central site runs on an Ethernet LAN. The only always-on WAN link is an Internet connection using wireless broadbandto a local ISP. AAA wants to enhance their service offering by creating a new E-Commerce web site where customers can browse and search a catalog of videotitles and select the ones they want for rental. The system will instantly communicate the order to the nearest store where employees pull the order and hold it untilthe customer picks it up. The service must operate on a 24x7 basis. AAA sees this new business strategy as a means to increase revenue and expand thebusiness nationally. They see an opportunity to expand the web site in the future to video, DVD and music sales on a worldwide level. The company wants all storesto be connected to the central site through WAN links. The company is upgrading the central inventory database so that sales and rentals can be postedimmediately in real-time. An Internet- based email and instant-messaging system will be set up for all headquarters employees and store managers to use. AAAbelieves that networking the stores will improve order fulfillment processes which will improve customer satisfaction and thus, boost revenue. It will also helpcommunication with store employees. AAA wants to upgrade the local LAN to a Gigabit and Fast Ethernet system to facilitate the demands of the new andupgraded systems. They have budgeted $500,000 for the networking equipment and another $10,000/month for the WAN charges including a faster Internetconnection.

QUESTION 150AAA Video operates a chain of 50 video rental stores located in the Northwestern United States. They currently have a Point-of-Sale (POS) system in which eachstore posts its daily sales data and inventory changes to a central database through dial-up communication. There is no interaction between the stores and thecentral system during business hours. The central site runs on an Ethernet LAN. The only always-on WAN link is an Internet connection using wireless broadbandto a local ISP. AAA wants to enhance their service offering by creating a new E-Commerce web site where customers can browse and search a catalog of videotitles and select the ones they want for rental. The system will instantly communicate the order to the nearest store where employees pull the order and hold it untilthe customer picks it up. The service must operate on a 24x7 basis. AAA sees this new business strategy as a means to increase revenue and expand thebusiness nationally. They see an opportunity to expand the web site in the future to video, DVD and music sales on a worldwide level. The company wants all storesto be connected to the central site through WAN links. The company is upgrading the central inventory database so that sales and rentals can be postedimmediately in real-time. An Internet- based email and instant-messaging system will be set up for all headquarters employees and store managers to use. AAAbelieves that networking the stores will improve order fulfillment processes which will improve customer satisfaction and thus, boost revenue. It will also helpcommunication with store employees. AAA wants to upgrade the local LAN to a Gigabit and Fast Ethernet system to ilitate the demands of the new and upgradedsystems. They have budgeted $500,000 for the networking equipment and another $10,000/month for the WAN charges including a faster Internet connection.They believe that 256Kbps speeds will be adequate to the stores. Since they have no staff capable of managing the new network, they will hire two engineers thatalready have the training and experience. The project must be complete in 6 months when the new inventory system goes online. The IT manager has concernsabout the security of the servers and workstations on the network when all stores become connected. He doesn'ant any Internet access to or from the stores. He isdepending on you to recommend an effective yet affordable solution that will protect his system from intruders.What are the business goals of AAA video that applyto this network design project?

Correct Answer: ABESection: Describe the Methodology used to design a networkExplanation



A Cisco ASR is used to terminate Teleworker solutions, not a 2900 series router. Hybrid teleworker uses Aironet, Advanced teleworker uses 880, both use IPphones.google: "at_a_glance_c45-652500.pdf" for details

The Cisco Virtual Office Solution for the Enterprise Teleworker is implemented using the Cisco 800 series ISRs. Each ISR has integrated switch ports that thenconnect to the user's broadband connection. The solution uses a permanent always-on IPsec VPN tunnel back to the corporate network. This architecture providesfor centralized IT security management, corporate-pushed security policies, and integrated identity services. In addition, this solution supports the enterpriseteleworker needs through advanced applications such as voice and video. For example, the enterprise teleworker can take advantage of toll bypass, voicemail, andadvanced IP phone features not available in the PSTN.

Enterprise Teleworker ModuleThe enterprise teleworker module consists of a small office or a mobile user who needs to access services of the enterprise campus. As shown in Figure 2-14,mobile users connect from their homes, hotels, or other locations using dialup or Internet access lines. VPN clients are used to allow mobile users to securelyaccess enterprise applications. The Cisco Virtual Office solution provides a solution for teleworkers that is centrally managed using small integrated service routers(ISR) in the VPN solution. IP phone capabilities are also provided in the Cisco Virtual Office solution, providing corporate voice services for mobile users.

QUESTION 291Which of these is the equation used to derive a 64 Kbps bit rate?

A. 2 x 8 kHz x 4-bit code wordsB. 8 kHz x 8-bit code wordsC. 2 x 4-bit code words x 8 kHz


D. 2 x 4 kHz x 8-bit code words

Correct Answer: DSection: Describe the Methodology used to design a networkExplanation

Explanation/Reference:Explanation:While the human ear can sense sounds from 20 to 20, 000 Hz, and speech encompasses sounds from about 200 to 9000 Hz, the telephone channel was designedto operate at about 300 to 3400 Hz. This economical range carries enough fidelity to allow callers to identify the party at the far end and sense their mood. Nyquistdecided to extend the digitization to 4000 Hz, to capture higher-frequency sounds that the telephone channel may deliver. Therefore, the highest frequency for voiceis 4000 Hz. According to Nyquist theory, we must double the highest frequency, so 2x4kHz = 8kHz. Each sample will be encoded into a 8-bit code. Therefore 8kHzx 8-bit code = 64 Kbps (notice about the unit Kbps: 8kHz = 8000 samples per second so 8000 x 8-bit = 64000 bit per second = 64 Kilobit per second = 64 Kbps)Link: http://encyclopedia2.thefreedictionary.com/Nyquist+theorem

Note:Nyquist theory:"When sampling a signal (e.g., converting from an analog signal to digital), the sampling frequency must be greater than twice the bandwidth of the input signal inorder to be able to reconstruct the original perfectly from the sampled version."

Multiport NIC servers should never be used in the access layer.E. Layer 2 clustering implementation requires servers to be Layer 2 adjacent.

Correct Answer: CESection: Design Basic Enterprise Campus NetworksExplanation


User access is primarily layer 2 in nature, layer 2 clustering is possible only in layer 2 Here is the Explanation: from the Cisco press CCDA certification guide Figure4-8. Enterprise Data Center Infrastructure Overview



Defining the DC Access LayerThe data center access layer's main purpose is to provide Layer 2 and Layer 3 physical port density for various servers in the data center. In addition, data centeraccess layer switches provide high- performance, low-latency switching and can support a mix of oversubscription requirements. Both Layer 2 and Layer 3 access(also called routed access) designs are available, but most data center access layers are built using Layer 2 connectivity. The Layer 2 access design uses VLANtrunks upstream, which allows data center aggregation services to be shared across the same VLAN and across multiple switches. Other advantages of Layer 2access are support for NIC teaming and server clustering that requires network connections to be Layer 2 adjacent or on the same VLAN with one another.

On which major functional area and which submodule of the Enterprise Composite Network Model will you be keying your efforts?

A. Enterprise Edge; Internet ConnectivityB. Enterprise Campus; Network ManagementC. Service Provider; ISPD. Campus Infrastructure; Building AccessE. Enterprise Campus; Campus InfrastructureF. Edge Distribution; Call Detail Log



QUESTION 342AAA Video operates a chain of 50 video rental stores located in the Northwestern United States. They currently have a Point-of-Sale (POS) system in which eachstore posts its daily sales data and inventory changes to a central database through dial-up communication. There is no interaction between the stores and thecentral system during business hours. The central site runs on an Ethernet LAN. The only always-on WAN link is an Internet connection using wireless broadbandto a local ISP. AAA wants to enhance their service offering by creating a new E-Commerce web site where customers can browse and search a catalog of videotitles and select the ones they want for rental. The system will instantly communicate the order to the nearest store where employees pull the order and hold it untilthe customer picks it up. The service must operate on a 24x7 basis. AAA sees this new business strategy as a means to increase revenue and expand thebusiness nationally. They see an opportunity to expand the web site in the future to video, DVD and music sales on a worldwide level. The company wants all storesto be connected to the central site through WAN links. The company is upgrading the central inventory database so that sales and rentals can be postedimmediately in real-time. An Internet-based email and instant-messaging system will be set up for all headquarters employees and store managers to use. AAAbelieves that networking the stores will improve order fulfillment processes which will improve customer satisfaction and thus, boost revenue. It will also helpcommunication with store employees. AAA wants to upgrade the local LAN to a Gigabit and Fast Ethernet system to facilitate the demands of the new andupgraded systems. They have budgeted $500,000 for the networking equipment and another $10,000/month for the WAN charges including a faster Internetconnection. They believe that 256Kbps speeds will be adequate to the stores. Since they have no staff capable of managing the new network, they will hire twoengineers that already have the training and experience. The project must be complete in 6 months when the new inventory system goes online. The IT managerhas concerns about the security of the servers and workstations on the network when all stores become connected. He doesn'ant any Internet access to or from thestores. He is depending on you to recommend an effective yet affordable solution that will protect his system from intruders.Which two are business constraintsimposed by the AAA Video Company on this new network design project? (Choose two.)

A. the $10,000/month WAN budgetB. the installation of WAN links to all storesC. the lack of any existing IT staff


D. video sales through the global InternetE. real-time posting of store sales
