SIMULATION You need to configure SRV1 as a DNS server. SRV1 must be able resolve names from the contoso.com domain by using DC1. All other names must be resolved by using the root hint servers. To complete this task, sign in the required computer or computers. Answer:

Phase 1: Create a secondary zone Phase 2: Configure root hints Phase 1: Create a secondary zone Create a secondary zone To create a secondary zone, select the relevant method and follow the steps. Here's how to create a secondary look up zone using DNS Manager. Step 1: From the Windows desktop, open the Start menu, select Windows Administrative Tools > DNS. Step 2: In the console tree, connect to the DNS server [here Srv1] you wish to manage, expand the DNS server, right-click, then select New Zone. Step 3: On the New Zone Wizard page, select Next. Step 4: On the Zone Type page, select Secondary zone. Step 5: On the Zone Name page, specify the name of the secondary zone. The name of the zone must match the name of the primary zone to replicate from. For example, south.contoso.com. [Here: contoso.com] Step 6: On the Master DNS Servers page, specify the IP addresses of one or more DNS servers that host copies of the primary zone. You need to ensure that the primary zone allows transfers to the DNS server hosting the secondary zone. For example, 172.23.90.124. [Here: dc1] Step 7: Select Finish on the Completing the New Zone Wizard. Phase 2: Configure root hints Root hints servers are used to help resolving DNS address information when the DNS server is unable to resolve the query locally from a hosted zone or the DNS server cache. Root hints name servers are populated by default in new installations. You can edit the list of root name servers if required by navigating to the Root Hints tab of the DNS server properties dialog box or by using PowerShell. Step 1: From the Windows desktop, open the Start menu, select Windows Administrative Tools > DNS. Step 2: Select and hold (or right-click) your server, and then select Properties. Step 3: Select the Root Hints tab, select the item to edit, and then select Edit. Step 4: Enter the fully qualified domain name, then select Resolve. Verify the IP address, and if necessary edit the IP address. Step 5: Select OK. Review the updated root hint server in the list, when you're ready select OK. You'll notice the name server has a trailing dot (.). Reference:
