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
fabnkam.com.
You need to configure Server1 to support the resolution of names in fabnkam.com. The solution
must ensure that users in contoso.com can resolve names in fabrikam.com if the WAN link fails.
What should you do on Server1?
A.
Create a stub zone.
B.
Add a forwarder.
C.
Create a secondary zone.
D.
Create a conditional forwarder.

for information about this zone. The zone at this server must be obtained from another remote DNS
server computer that also hosts the zone.
With secondary, you have ability to resolve records from the other domain even if its DNS servers
are temporarily unavailable.
While secondary zones contain copies of all the resource records in the corresponding zone on the
master name server, stub zones contain only three kinds of resource records:
A copy of the SOA record for the zone.
Copies of NS records for all name servers authoritative for the zone.
Copies of A records for all name servers authoritative for the zone.

I think it is a “stub zone” :
A stub zone is a copy of a zone that contains only necessary resource records (Start of
Authority (SOA), Name Server (NS), and Address/Host (A) record) in the master zone
and acts as a pointer to the authoritative name server. The stub zone allows the server to
forward queries to the name server that is authoritative for the master zone without going
up to the root name servers and working its way down to the server. While a stub zone can
improve performance, it does not provide redundancy or load sharing.
If the wan link fails a stub zone can’t forward anything to Server2.
Absolutely sure that tha answer is a Secondary Zone, which is a copy of that zone provided by the authoritative DNS Server for that zone.
I agree Manuel. A stub zone would only resolve servers. We’d need resolve all computers so a secondary is the right answer IMHO.
