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.
