Your company has one main office and 50 branch offices.
You have a wide area network (WAN) link that connects all branch offices to the main office. The network consists of 10 Active Directory domains.
Users from all domains are located in the branch offices.
You plan to configure each branch office as an Active Directory site. The domain is configured as shown in the exhibit.
You need to plan the deployment of domain controllers in the branch offices to meet the following requirements:
- Users must be able to log on if a WAN link fails.
- Minimize replication traffic between offices.
What should you include in your plan?
Exhibit:
A. Implement a domain controller in each branch office. Enable Universal Group Membership Caching.
B. Implement a domain controller in each branch office. Configure DNS to use a single Active Directory- integrated zone.
C. Implement a domain controller in each branch office. Configure the domain controller as a global catalog server.
D. Implement a read-only domain controller (RODC) in each branch office. Configure the domain controller as a global catalog server.
