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.Exam Ref: 70-410: Installing and Configuring Windows Server 2012 R2, Chapter4: Deploying and configuring
core network services, Objective 4.3: Deploy and Configure the DNS service, p.233

step 1 – run following cmd on authoritative DNS Server:
DNScmd (servername) /config /enableglobalnamessupport 1
step 2 – create an AD integrated zone called -GlobalNames that is forest wide with dynamic updates disabled.
Then add a CNAME for each single-label required.
