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 “.”.
I’m pretty sure that in order to keep a DNS server from resolving internet host names you need to make a Dot zone or “.”, not “root”…

Answer C also looks valid. We can have the queries getting forwarded to a non-existent DNS server and hence they never get resolved.

D is correct.
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.

The C is not correct
If the forwader does not answer, the request is redirected to the root.

it should be the “.” zone not the zone named Root. The name Root by itself has no significance, i think.

I have verified this in a newly spun up Server 2012 R2 VM with just DNS role installed.
Creating a primary zone named “root” does not block outside requests.
Creating a primary zone named “.” actually converts the DNS server into a primary root zone, thus breaking outside requests.
The proper answer is “D”.
