Your network contains an Active Directory domain named contoso.com. The network contains 500
client computers that run Windows 8. All of the client computers connect to the Internet by using a
web proxy.
You deploy a server named Server1 that runs Windows Server 2012 R2. Server1 has the DNS Server
server role installed.
You configure all of the client computers to use Server1 as their primary DNS server.
You need to prevent Server1 from attempting to resolve Internet host names for the client
computers.
What should you do on Server1?
A.
Create a primary zone named “root”.
B.
Create a primary zone named “GlobalNames”.
C.
Create a forwarder that points to 169.254.0.1.
D.
Create a primary zone named “.”.

The DNS root server hosts the root zone represented as a dot ( . ). The root zone contains a delegation to a zone in the next level of the hierarchy, the com zone. The delegation in the root zone tells the DNS root server that, to find the com zone, it must contact the Com server. Likewise, the delegation in the com zone tells the Com server that, to find the contoso.com zone, it must contact the Contoso server.

Your root zone looks more like a boob to me. 😉

Leanne if you see you need to ” to prevent Server1″ to allow the “attempting to resolve” from the computer in that situation you need to create the root server of the dns.
so the current answer is A.

The answer is D as tested in Microsoft AD integrated DNS.
Test:
Hyper-V LAB on Windows Server 2012 R2 with ADDS and DNS installed. When you you create a DNS primary zone with the name of “root” it just adds a single-label zone called root. (Example: A record for yahoo has a FQDN of yahoo.root.) When creating a DNS primary zone with the name of “.” Microsoft DNS interprets the “.” and renames the zone to “.(root)” which in MS DNS means the root of everything. (Example: A record for YAHOO has a FQDN of YAHOO..)
Information:
DNS is a hierarchy and the “.” is the top or the root of the hierarchy. Here is a good TechNet article How IT Works Domain Name System https://technet.microsoft.com/en-us/magazine/2005.01.howitworksdns.aspx
I hope this helps everyone. =)
