Your network consists of two Active Directory forests. The Active Directory forests are configured as
shown in the following table. (Click the Exhibit)

You need to prepare the environment to allow users to access resources in all domains from both
forests. The solution must require the minimum amount of administrative effort. What should you
do first?

A.
Set the functional level of the contoso.com forest to Windows Server 2008.

B.
Set the functional level of the fabrikam.com forest to Windows Server 2003.

C.
Upgrade all domain controllers in the fabrikam.com domain to Windows Server 2008. Set the
domain functional level of fabrikam.com to Windows Server 2008.

D.
Upgrade all domain controllers in the fabrikam.com and company2.fabrikam.com domains to
Windows Server 2008. Set the functional level of the fabrikam.com forest to Windows Server 2008.

Explanation:
To allow all the users to access resources in all the domains from both the forests without putting
too much of administrative effort, you need to set the functional level of the Fabrikam.com forest
from Windows Server 2000 to Windows Server 2003. This is because Contoso.com already runs at
the functional level of Windows Server 2003. Contoso.com also contains domain controllers that run
Windows Server 2008. Forest functional level of Windows Server 2003 supports Windows Server
2008 domain controllers and Windows Server 2003 domain controllers. The forest functional level of
the Contoso.com or Fabrikam.com should not be raised to Windows Server 2008 because it does not
support Windows Server 2003 domain controllers.
