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

What should you do?
A.
On DC2, create a forwarder.
B.
On DC1, create a delegation.
C.
On DC1, change the replication scope of the contoso.com zone.
D.
On DC2, modify the Zone Transfers settings.
Why not C
“On DC1, change the replication scope of the contoso.com zone.” ??

You can also modify the scope of zone database replication to keep copies on all domain controllers throughout the enterprise or on all domain controllers in the AD DS domain, regardless of whether they are running the DNS server.
Option “create a delegation” would set up a delegation on DC1 that would specify any queries for the child.contoso.com domain made on DC1 can be made authoritative on DC2. However, this would not make requests on DC2 for the contoso.com domain authoritative, so this option is invalid.
