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. Configure dynamic updates for contoso.com.
D. Create a GlobalNames zone.
Explanation:
Although a GlobalNames zone is required in order to
resolve single-label names, GNZs must be AD-integrated.
Since this is a standard primary zone (as opposed to an ADDS primary zone), we must first integrate the zone into Active Directory.
