Your network contains an Active Directory domain named contoso.com. The domain contains six
domain controllers named DC1, 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 DCG.
What should you do first?

A.
Change the zone replication scope.

B.
Create an Active Directory connection object.

C.
Create an Active Directory site link.

D.
Create an application directory partition.

Explanation:
You can store Domain Name System (DNS) zones in the domain or application directory partitions of
Active Directory Domain Services (AD DS). 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.
