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 Directory- integrated
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.
