Your company has a main office and three branch offices. The main office is located in Austin. The
branch offices are located in Denver, San Diego, and Chicago.
The network contains an Active Directory forest. The forest contains a single domain. Each office is
configured as an Active Directory site.
The site in Austin contains four domain controllers that run Windows Server 2008 R2 and are
configured as global catalog servers. The sites in Denver, San Diego, and Chicago each contain a
read-only domain controller (RODC) that runs Windows Server 2008 R2. No other domain controllers
exist on the network.
You plan to deploy an Exchange Server 2013 organization. Exchange Server 2013 servers will be
deployed in the Austin, Denver, and San Diego sites. Users from the Chicago site will access their
mailbox remotely.
You need to recommend changes to the Active Directory infrastructure to support the planned
deployment of Exchange Server 2013.
What should you recommend?
A.
Replace the RODCs in the Denver and San Diego sites with domain controllers that are configured
as global catalog servers.
B.
Configure the RODCs in the Denver and San Diego sites as read-only global catalog servers.
C.
Configure Active Directory automatic site coverage for the Chicago site.
D.
Upgrade all of the RODCs to Windows Server 2012.
