What should you do?

Your network contains an Active Directory forest named contoso.com. The forest contains five domains. You manage DNS for the contoso.com domain only. You are not responsible for managing DNS for the child domains. The DNS servers in a child domain named research.contoso.com are reconfigured often. You need to ensure that clients in contoso.com can resolve addresses in research.contoso.com.

The solution must minimize zone replication traffic.

What should you do?
A . Create a primary zone for research.contoso.com on the DNS servers of contoso.com
B . Create a secondary zone for research.contoso.com on the DNS servers of contoso.com
