Your company has a main office and 100 branch offices. The network consists of one Active
Directory domain that contains 10,000 users. You plan to deploy one Windows Server 2008 domain
controller in each branch office. You need to recommend a solution to minimize network traffic
during the installation of Active Directory Domain Services (AD DS) on each branch office domain
controller. What should you recommend?
A.
Install AD DS by using the Install from Media feature.
B.
Install AD DS and configure the read-only domain controller (RODC) option.
C.
Install a Server Core installation of Windows Server 2008, and then install AD DS.
D.
Disable the Global Catalog option on each branch office domain controller. Enable Universal
Group Membership Caching from each branch office site.
Explanation:
To minimize the network traffic during the installation of Active Directory Domain Services (AD DS)
on each branch office domain controller, you need to use Media feature Install option to install AD
DS. You can use ntdsutil to create an installation media for the installation of Windows Server 2008
domain controller. By installing from media, you can minimize the replication of directory data over
the network. This helps you install additional domain controllers in remote sites more efficiently.
