Your company has a main office and a branch office that are configured as a single Active Directory forest. The functional level of the Active Directory forest is Windows Server 2003. There are four Windows Server 2003 domain controllers in the main office. You need to ensure that you are able to deploy a read-only domain controller (RODC) at the branch office. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A.
Raise the functional level of the forest to Windows Server 2008.
B.
Deploy a Windows Server 2008 domain controller at the main office.
C.
Raise the functional level of the domain to Windows Server 2008.
D.
Run the adprep/rodcprep command.
RODC only became available in Server 2008. It doesn’t require raising the Forest functional level or the domain functional level.
u
It does require that you install a windows server 2008 RODC but before you do that you need to prep the Active Directory to accept the Windows 2008 DC
