Your network consists of one Active Directory forest. The functional level of the forest is Windows
Server 2003. You upgrade all domain controllers from Windows Server 2003 SP2 to Windows Server
2008 R2. You plan to deploy the first read-only domain controller (RODC) in the forest. You need to
prepare the network for the installation of the RODC. What should you do?

A.
Run adprep /rodcprep on any computer in the forest.

B.
Run adprep /forestprep on the schema operations master server.

C.
Raise the forest functional level to Windows Server 2008 R2.

D.
Raise the domain functional level to Windows Server 2008 R2.

Explanation:
To deploy the first RODC to the forest which operates at the functional level of Windows Server
2003, you need to Run adprep /rodcprep on any computer in the forest. Before you can install an
RODC in a Windows 2000 Server or Windows Server 2003 forest, you must prepare the forest by
running adprep /rodcprep. You can run adprep /rodcprep on any computer in the forest. You can run
it multiple times if necessary.
