Your network contains an Active Directory domain named contoso.com. The domain contains six domain
controllers named DO, DC2, DC3, DC4, DC5 and DC6. Each domain controller has the DNS Server server role
installed and hosts an Active Directory-integrated zone for contoso.com.
You plan to create a new Active Directory-integrated zone named litwareinc.com that will be used for testing.
You need to ensure that the new zone will be available only on DC5 and DC6.
What should you do first?
A.
Create an Active Directory connection object.
B.
Create an Active Directory site link.
C.
Create an application directory partition
D.
Change the zone replication scope.
Explanation:
Zone replication scope:All domain controllers in a specified application directory partition
Replicates zone data according to the replication scope of the specified application directory partition. For a
zone to be stored in the specified application directory partition, the DNS server hosting the zone must be
enlisted in the specified application directory partition. Use this scope when you want zone data to be replicated
to domain controllers in multiple domains but you do not want the data to replicate to the entire forest.
C . Create an application directory partition.
A partition is a data structure in AD DS that distinguishes data for different replication purposes. When you create an application directory partition for DNS, you can control the scope of replication for the zone that is stored in that partition
