You need to plan the deployment of domain controllers

Your company has a main office, three regional offices, and six branch offices. The network links are configured as shown in the exhibit.
The network consists of one Active Directory domain.
You create an Active Directory site for each office. You create a site link for each wide area network (WAN) link. The Bridge all site links option is disabled.

You need to plan the deployment of domain controllers.

The solution must meet the following requirements.

– Windows PowerShell must be installed on all domain controllers in each regional office.
– Domain user account passwords stored on the domain controllers must be protected if a branch office domain controller is stolen.

What should you do?

Exhibit:

A.
In each branch office and in each regional office, install a Server Core installation of Windows Server 2008 and configure a writable domain controller.

B.
In each branch office and in each regional office, install a full installation of Windows Server 2008 and configure a read-only domain controller (RODC).

C.
In each branch office, install a Server Core installation of Windows Server 2008 and configure a read- only domain controller (RODC). In each regional office, install a full installation of Windows Server 2008 and configure a writable domain controller.

D.
In each branch office, install a full installation of Windows Server 2008 and configure a read- only domain controller (RODC). In each regional office, install a Server Core installation of Windows Server 2008 and configure a writable domain controller.
