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.
You need to ensure that DC2 can provide authoritative responses for queries to the contoso.com
namespace.
What should you do?
A.
On DC1, create a delegation.
B.
On DC1, change the replication scope of the contoso.com zone.
C.
On DC2, create a forwarder.
D.
On DC2, modify the Zone Transfers settings.
Explanation:
For DC1 to be able to provide authoritative responses to DNS queries the replication scope should be
changed accordingly so that it has the zone data for the contoso.com domain.
C, On DC2, create a forwarder. A delegation for child.contoso.com also needs to be created on DC1, but it’s the forwarder which allows DC2 to resolve names in contoso.com.

Can’t believe I said that, what a dummy I am. Forwarder + delegation is the most common way of doing it but the question says DC2 needs to be authoritative, so the answer is correct, replicate contoso.com to all the DCs in the forest.
