You remove several computers from the network.
You need to ensure that the host (A) records for the removed computers are automatically
deleted from the contoso.com DNS zone.
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 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?

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 run nslookup.exe as shown in the following Command Prompt window.

You need to ensure that you can use Nslookup to list all of the service location (SRV)
resource records for contoso.com.
What should you modify?

Your network contains an Active Directory domain named contoso.com.
The contoso.com DNS zone is stored in Active Directory. All domain controllers run
Windows Server 2008 R2.
You need to identify if all of the DNS records used for Active Directory replication are
correctly registered.
What should you do?

Your network contains an Active Directory forest. The forest contains one domain and three
sites. Each site contains two domain controllers. All domain controllers are DNS servers.
You create a new Active Directory-integrated zone.
You need to ensure that the new zone is replicated to the domain controllers in only one of
the sites.
What should you do first?

Your network contains a single Active Directory forest. The forest contains two domains
named contoso.com and sales.contoso.com. The domain controllers are configured as
shown in the following table.

All domain controllers run Windows Server 2008 R2. All zones are configured as Active
Directory- integrated zones.
You need to ensure that contoso.com records are available on DC3.
Which command should you run?

You have a DNS zone that is stored in a custom application directory partition.
You install a new domain controller.
You need to ensure that the custom application directory partition replicates to the new
domain controller.

What should you use?

Your network contains an Active Directory domain named contoso.com. All domain
controllers run Windows Server 2008 R2. The functional level of the domain is Windows
Server 2008 R2. The functional level of the forest is Windows Server 2008.
You have a member server named Server1 that runs Windows Server 2008.
You need to ensure that you can add Server1 to contoso.com as a domain controller.
What should you run before you promote Server1?
