Your network contains an Active Directory domain named contoso.com.
The Active Directory sites are configured as shown in the Sites exhibit:
You need to ensure that DC1 and DC4 are the only servers that replicate Active Directory changes between the sites.
What should you do?
Exhibit:
A. Configure DC1 as a preferred bridgehead server for IP transport.
B. Configure DC4 as a preferred bridgehead server for IP transport.
C. From the DC4 server object, create a Connection object for DC1.
D. From the DC1 server object, create a Connection object for DC4.
Correct Answer: B
Explanation/Reference:
Same question as L/Q4, with a different Exhibit, so with a different answer.

Bridgehead Servers
A bridgehead server is the domain controller designated by each site’s KCC to take control of intersite replication. The bridgehead server receives information replicated from other sites and replicates it to its site’s other domain controllers. It ensures that the greatest portion of replication occurs within sites rather than between them.
In most cases, the KCC automatically decides which domain controller acts as the bridgehead server. However, you can use Active Directory Sites and Services to specify which domain controller will be the preferred bridgehead server by using the following steps:
1. In Active Directory Sites and Services, expand the site in which you want to specify the preferred bridgehead server.
2. Expand the Servers folder to locate the desired server, right-click it, and then choose Properties.
3. From the list labeled Transports available for intersite data transfer, select the protocol(s) for which you want to designate this server as a preferred bridgehead server and then click Add.
