You need to ensure that the new zone will be available only on DC5 and DCG

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.
