Your network contains multiple subnets.
On one of the subnets, you deploy a server named Server1 that runs Windows Server 2012
R2.
You install the DNS Server server role on Server1, and then you create a standard primary
zone named contoso.com.
You need to ensure that client computers can resolve single-label names to IP addresses.
What should you do first?
A.
Create a reverse lookup zone.
B.
Convert the contoso.com zone to an Active Directory-integrated zone.
C.
Create a GlobalNames zone.
D.
Configure dynamic updates for contoso.com.
Explanation:
You should use GlobalNames zone to take advantage of single-label names. This will also
ensure that the zone remains valid.
