Your network contains an Active Directory domain named contoso.com. All domain controllers run
Windows Server 2012 R2. The domain contains two domain controllers. The domain controllers are
configured as shown in the following table.

The Branch site contains a perimeter network.
For security reasons, client computers in the perimeter network can communicate with client
computers in the Branch site only. You plan to deploy a new RODC to the perimeter network in the
Branch site. You need to ensure that the new RODC will be able to replicate from DC10. What
should you do first on DC10?

A.
Enable the Bridge all site links setting.

B.
Run the Active Directory Domain Services Configuration Wizard.

C.
Create an Active Directory site link bridge.

D.
Create an Active Directory site.

Explanation:
A)
Site link transitivity is controlled by the Bridge all site links option on the properties pages of
transport folders (such as IP or SMTP) in the Active Directory Sites and Services snapin. Site link
transitivity is enabled by default.
B)

C)

If you cannot place a writable Windows Server 2008 domain controller in the nearest site to the
RODC, RODC replication depends on a site link bridge between the site links that contain the site of
the RODC and the site of the writable Windows Server 2008 domain controller.
D)
