You are the systems administrator for your company. You are migrating from Windows Small Business Server (SBS) 2003 to Windows Essential Business Server (EBS) 2008. You migrate the Domain Name System (DNS) settings from an existing DNS server to the Windows EBS servers. You want to ensure that the DNS Server service functions properly on the Windows EBS servers.
What should you do?
A.
Create a CNAME record for the Management Server in the forward lookup zone.
B.
Create a CNAME record for the Messaging Server in the forward lookup zone.
C.
Create a CNAME record for the Security Server in the forward lookup zone.
D.
Create a SRV record for the Security Server in the forward lookup zone.
Explanation:
You should create a CNAME record for the Security Server in the forward lookup zone. When you migrate DNS settings from a DNS server that is not integrated with Active Directory, you should do the following on the Management Server and the Messaging Server to ensure that the DNS settings are correct:
* Ensure that both forward and reverse lookup zones are migrated correctly.
* Ensure that both forward and reverse lookup zones are integrated with Active Directory as primary zones.
* Remove legacy name servers from the forward and reverse lookup zones.
* Add a CNAME record for Web Proxy Automatic Discovery (WPAD).
* Remove any forwarders and confirm the presence of root hints.To add a CNAME record for WPAD, you should create a new CNAME record in the forward lookup zone on the Management Server or the Messaging Server and specify the fully qualified domain name (FQDN) of the Security Server.
You should not create a CNAME record for the Management Server or the Messaging Server in the forward lookup zone. The CNAME record is required for WPAD, which is provided by the Security Server. Therefore, you should create a CNAME record and specify the FQDN of the Security Server.
You should not create a SRV record for the Security Server in the forward lookup zone. To ensure that the DNS Server services function properly, you should add a CNAME record for WPAD that is provided by the Security Server. A SRV record cannot be used to create a record for WPAD.
