Your company has one main office and one branch office. The branch office is connected to the main office by using a wide area network (WAN) link.
The network consists of one Active directory domain.
The branch office has two member servers that run Windows Server 2008 R2. One of the servers is configured as a file server that hosts shared folders.
The branch office has a local administrator. The main office has one standard primary DNS zone that is hosted on a DNS server.
The branch office grows from 100 client computers to 1,000 client computers.
You need to recommend a name resolution solution for the branch office to meet the following requirements:
Users must be able to access file shares on the local server if a WAN link fails.
The branch office administrator must be able to modify Active Directory objects while at the branch office if a WAN link fails.
What should you recommend?
A. Promote the member server to a domain controller and configure the DNS role. Create a standard secondary zone.
B. Promote the member server to a domain controller and configure the DNS role. Create a new standard primary zone.
C. Promote the member server to a read-only domain controller (RODC) and configure the DNS role. Create a primary read–only zone.
D. Promote the member server to a read-only domain controller (RODC) and configure the DNS role. Create a new standard secondary zone.
