Your company has a main office. The main office is configured as an Active Directory site. The network consists of one Active Directory domain.
All domain controllers run Windows Server 2008.
All DNS zones are Active Directory-integrated. Administrators frequently join new client computers to the domain.
You plan to deploy a new site in a new branch office. The new branch office is connected to the main office by using a single wide area network (WAN) link.
You need to enable branch office administrators to successfully join computers to the domain if a WAN link fails. The solution must provide the highest level of security for the domain controllers.
What should you do?
A. Deploy a writable domain controller in the branch office site.
B. Deploy an additional writable domain controller in the main site.
C. Deploy a read-only domain controller (RODC) in the new site. Configure a stub zone in the main site.
D. Deploy a read-only domain controller (RODC) in the new site. Configure a primary read-only zone in the branch office site.
