Your company has a main office and a new branch office. The network consists of one Active directory domain.
The branch office contains two member servers that run Windows Server 2008 R2. One of the servers is configured as a file server that hosts shared folders. An administrator in the branch office is responsible for maintaining the servers.
You have a single DNS zone that is hosted on a DNS server located in the main office.
A wide area network (WAN) link between the branch office and the main office is unreliable.
You need to recommend a network services solution for the new branch office. The solution must meet the following requirements:
- Users must be able to log on to the domain if a WAN link fails.
- Users must be able to access file shares on the local server if a WAN link fails.
- Branch office administrators must be prevented from initiating changes to Active Directory.
- Branch office administrators must be able to make configuration changes to the servers in the branch office.
What should you recommend?
A. Promote the member server to a domain controller and add the branch office administrators to the Domain Admins group.
B. Promote the member server to a read-only domain controller (RODC) and add the branch office administrators to the Domain Admins group.
C. Promote the member server to a read-only domain controller (RODC) and configure the DNS role. Delegate administrative rights to the local branch office administrator.
D. Promote the member server to a domain controller and configure the DNS role. Create an organizational unit (OU) for each branch office and delegate administrative rights to the local branch office administrator.
