Your network contains an Active Directory forest. The forest contains two domains named
contoso.com and fabrikam.com. All of the DNS servers in both of the domains run Windows Server
2012 R2.
The network contains two servers named Server1 and Server2. Server1 hosts an Active Directoryintegrated zone for contoso.com. Server2 hosts an Active Directory-integrated zone for
fabrikam.com. Server1 and Server2 connect to each other by using a WAN link.
Client computers that connect to Server1 for name resolution cannot resolve names in
fabrikam.com.
You need to configure Server1 to resolve names in fabrikam.com. The solution must NOT require
that changes be made to the fabrikam.com zone on Server2.
What should you create?

A.
A trust anchor

B.
A stub zone

C.
A zone delegation

D.
A secondary zone

Explanation:
A stub zone is a copy of a zone that contains only those resource records necessary to identify the
authoritative Domain Name System (DNS) servers for that zone. A stub zone is used to resolve
names between separate DNS namespaces. This type of resolution may be necessary when a
corporate merger requires that the DNS servers for two separate DNS namespaces resolve names
for clients in both namespaces.
