You need to prevent Server1 from attempting to resolve Internet host names for the client computers

Your network contains an Active Directory domain named contoso.com. The network contains 500 client
computers that run Windows 2012. All of the client computers connect to the Internet by using a web proxy.
You deploy a server named Server1 that runs WindowsServer 2012. 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 forwarder that points to 169.254.0.1.

B.
Create a primary zone named “GlobalNames”.

C.
Remove all root hints.

D.
Create a zone delegation for GlobalNames.contoso.com.

Explanation:
Root Hints are a vital cog in configuring your DNS Server. If your server receives a query for an
unknown domain, then the root hints give a clue as to where to search for the answer.
If you operate internal root DNS servers on a private network that is not connected to the Internet, edit or
replace root hints to point to your own internal root DNS servers. Delete root hints from your internal root DNS
servers.
