Your network contains a single Active Directory domain that has two sites named Site1 and
Site2. Site1 has two domain controllers named DC1 and DC2. Site2 has two domain
controllers named DC3 and DC4.
DC3 fails.
You discover that replication no longer occurs between the sites.
You verify the connectivity between DC4 and the domain controllers in Site1.
On DC4, you run repadmin.exe /kcc.
Replication between the sites continues to fail.
You need to ensure that Active Directory data replicates between the sites.
What should you do?
A.
From Active Directory Sites and Services, modify the properties of DC3.
B.
From Active Directory Sites and Services, modify the NTDS Site Settings of Site2.
C.
From Active Directory Users and Computers, modify the location settings of DC4.
D.
From Active Directory Users and Computers, modify the delegation settings of DC4.

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.
