Your company has one main office and five new branch offices.
The branch offices are connected to the main office across slow network links.
The network consists of one Active Directory domain. All domain controllers run Windows Server 2008.
Each office has a local server administrator.
You need to plan for the implementation of Windows Server 2008 domain controllers in each branch office. The solution must minimize the amount of network bandwidth used during the initial replication.
What should you include in your plan?

A.
Create an installation media by using ntdsutil.

B.
Run adprep /rodcprep on a server in each branch office.

C.
Create a System State back up by using Windows Server Backup in Windows Server 2008.

D.
Install Active Directory Lightweight Directory Services (AD LDS) in the branch office.
