Your network contains a single Active Directory domain named contoso.com. The domain contains two domain controllers named DC1 and DC2 that run Windows Server 2008 R2. DC1 hosts a primary zone for contoso.com. DC2 hosts a secondary zone for contosto.com. On DC1, you change the zone to an Active Directory-integrated zone and configure the zone to accept secure dynamic updates only.

You need to ensure that DC2 can accept secure dynamic updates to the contoso.com zone.

Which command should you run?

Your network contains an Active Directory domain named contoso.com. You plan to deploy a child domain named sales.contoso.com. The domain controllers in sales.contoso.com will be DNS servers for sales.contoso.com.

You need to ensure that users in contoso.com can connect to servers in sales.contoso.com by using fully qualified domain names (FQDNs).

What should you do?

You need to force a domain controller to register all service location (SRV) resource records in DNS.

Which command should you run?

Your network contains a domain controller that is configured as a DNS server. The server hosts an Active Directory-integrated zone for the domain.

You need to reduce how long it takes until stale records are deleted from the zone.

What should you do?

Your company has a main office and a branch office. The network contains an Active Directory domain named contoso.com. The DNS zone for contoso.com is configured as an Active Directory-integrated zone and is replicated to all domain controllers in the domain. The main office contains a writable domain controller named DC1. The branch office contains a read- only domain controller (RODC) named RODC1. All domain controllers run Windows Server 2008 R2 and are configured as DNS servers. You uninstall the DNS server role from RODC1.

You need to prevent DNS records from replicating to RODC1.

What should you do?

Your network contains an Active Directory domain named contoso.com. You create a GlobalNames zone. You add an alias (CNAME) resource record named Server1 to the zone. The target host of the record is server2.contoso.com. When you ping Server1, you discover that the name fails to resolve. You successfully resolve server2.contoso.com.

You need to ensure that you can resolve names by using the GlobalNames zone.

What should you do?

Your network contains an Active Directory domain named contoso.com. The domain contains a domain controller named DC1. DC1 hosts a standard primary zone for contoso.com.You discover that non-domain member computers register records in the contoso.com zone. All domain member computers must be allowed to register records in the contoso.com zone.

You need to prevent the non-domain member computers from registering records in the contoso.com zone.

What should you do first?

Your network contains an Active Directory forest named contoso.com. You plan to add a new domain named nwtraders.com to the forest.All DNS servers are domain controllers.

You need to ensure that the computers in nwtraders.com can update their Host (A) records on any of the DNS servers in the forest.

What should you do?

Your network contains an Active Directory domain. The domain contains two domain controllers named DC1 and DC2.DC1 hosts a standard primary DNS zone for the domain. Dynamic updates are enabled on the zone. DC2 hosts a standard secondary DNS zone for the domain.

You need to configure DNS to allow only secure dynamic updates.

What should you do first?

A server named DC1 has the Active Directory Domain Services (AD?DS) role and the Active Directory Lightweight Directory Services (AD?LDS) role installed. An AD?LDS instance named LDS1 stores its data on the C: drive.

You need to relocate the LDS1 instance to the D: drive.
