Your company has a single Active Directory domain. The company has a main office and
three branch offices. The domain controller in the main office runs Windows Server 2008 R2
and provides DNS for the main office and all of the branch offices. Each branch office
contains a file server that runs Windows Server 2008 R2. Users in the branch offices report
that it takes a long time to access network resources. You confirm that there are no

problems with WAN connectivity or bandwidth. You need to ensure that users in the branch
offices are able to access network resources as quickly as possible. Which two actions
should you perform? (Each correct answer presents part of the solution. Choose two.)

A.
Configure a standard primary zone in each of the branch offices.

B.
Configure forwarders that point to the DNS server in the main office.

C.
Configure a secondary zone in each of the branch offices that uses the main office DNS
server as a master.

D.
Install DNS servers in each of the branch offices.
