Each exercise will detail which console you are required to work on to carry out the

steps.

To start simply click on the named Server from the device list (located on the left

hand side of the screen) and click the Power on from the in tools bar. In some cases

the devices may power on automatically.

During the boot up process an activity indicator will be displayed in the name tab:

Exercise 1 - Configuring Windows

Clustering In this module, you will perform the tasks required to configure a Microsoft SQL

Server 2012 cluster.

To get a better understanding of this technology, please refer to your course material

or use your preferred search engine to research this topic in more detail.

Task 1 – Create a Reverse Lookup Zone in DNS

server

Servers that form part of a Failover Cluster must be able to resolve their numeric IP

addresses to Fully Qualified Domain Names (FQDNs). In this task, you will create a

reverse lookup zone and then verify that PLABCLUS01 and PLABCLUS02 will be able

to resolve their respective IP addresses to FQDNs.

To create a reverse look up zone, follow these steps:

Step 1

Ensure you have powered on the required devices mentioned in the Introduction of

this exercise.

Connect to PLABDC01.

Click Start, then go to Administrative Tools and select DNS.

Step 2

On DNS Manager window, expand PLABDC01 server then expand Reverse Lookup

Zones node.

Right-click on Reverse Lookup Zones and select New Zone…

Step 3

On the Welcome to the New Zone Wizard page, click Next.

Step 4

On the Zone Type page, ensure that Primary Zone option is selected.

Keep the other default selection and click Next.

Step 5

On the Active Directory Zone Replication Scope page, keep the default setting and

click Next.

Step 6

On the Reverse Lookup Zone Name page, verify that IPv4 Reverse Lookup Zone

option, click Next.

Step 7

On the Reverse Lookup Zone Name page, select Network ID option.

In the provided text box, type:

192.168.0.

Click Next.

Step 8

On the Dynamic Update page, keep the default selections and click Next.

Step 9

On the Completing the New Zone Wizard page, click Finish.

Step 10

Back on the DNS Manager window, click on Reverse Lookup Zone folder.

You will notice the 0.168.192.in-addr.arpa folder is the new zone.

Keep DNS Manager window open.

Keep all devices powered on in their current state and proceed to the next task.

Task 2 – Create PTR records for the servers

In this task, you will configure PLABCLUS01 and PLABCLUS02 to register their pointer

(PTR) records in DNS server.

To create the PTR records for the two servers, follow these steps:

Step 1

On PLABDC01, while DNS Manager is open, expand Forward Lookup Zones then

click on PRACTICELABS.COM.

From the right details pane, right-click on PLABCLUS01 then select Properties.

Step 2

On the PLABCLUS01 Properties dialog box, select Update associated pointer

(PTR) record check box.

Click OK.

Step 3

Next, right-click on PLABCLUS02 and select Properties.

Step 4

On the PLABCLUS02 Properties dialog box, if the Update associated pointer (PTR)

record check box is selected, clear the check box.

Click Apply.

Select Update associated pointer (PTR) record check box again.

Click OK.

Note: By doing the action above, this force a refresh on the PTR record of

PLABCLUS02 server.

Step 5

Back on the DNS Manager, click on 0.168.192.in-addr.arpa folder.

Press F5 to refresh the display.

Notice that you have pointer (PTR) records for each server.

Close DNS Manager.


Task 3 – Verify Name resolution

Close the Command Prompt window.

Step 3

Connect to PLABCLUS02 server.

Like in the previous step, open a command prompt.
