Your network consists of one Active Directory domain. All domain controllers run Windows Server
2003. You need to plan the forest and domain functional levels to support the following
requirements:
Read-only domain controllers (RODC)
Windows Server 2003 domain controllers
Which functional levels should you include in your plan?

A.
the forest functional level of Windows 2000 and the domain functional level of Windows Server
2003.

B.
the forest functional level of Windows Server 2003 and the domain functional level of Windows
Server 2003.

C.
the forest functional level of Windows Server 2003 and the domain functional level of Windows
Server 2008.

D.
the forest functional level of Windows Server 2008 and the domain functional level of Windows
Server 2008.

Explanation:
To create an Active Directory forest and domain functional levels to support Read-only domain
controllers (RODC) and Windows Server 2003 domain controllers, you need to create both the forest
and domain functional levels of Windows Server 2003. This is because only when you use both the
forest and domain functional levels of Windows Server 2003, you will be able to support Read-only
domain controllers (RODC) and Windows Server 2003 domain controllers.
