Your company has 250 branch offices. Your network contains an Active Directory domain. The domain
controllers run Windows Server 2008 R2. You plan todeploy Read-only Domain Controllers (RODCs) in the
branch offices.
You need to plan the deployment of the RODCs to meet the following requirements:
Build each RODC at the designated branch office.
Ensure that the RODC installation source files do not contain cached secrets.
Minimize the bandwidth used during the initial synchronization of Active Directory Domain Services (ADDS).
What should you include in your plan?
A.
Use Windows Server Backup to perform a full backup of an existing domain controller. Use the backup to
build the new RODCs.
B.
Use Windows Server Backup to perform a custom backup of the critical volumes of an existing domain
controller. Use the backup to build the new RODCs.
C.
Create a DFS namespace that contains the Active Directory database from one of the existing domain
controllers. Build the RODCs by using an answer file.
D.
Create an RODC installation media. Build the RODCs from the RODC installation media.
Explanation:
INSTALLATION OF AD DS FROM MEDIA
The Ntdsutil command is used to create installationmedia for additional domain controllers that you are
creating in a domain. By using the Install from Media (IFM) option, you can minimize the replication of directory
data over the network. This helps you install additional domain controllers in remote sites more efficiently.
Read-only domain controller (RODC) installation media must be used to install an RODC. For RODC
installation media, the ntdsutil command removes any cached secrets, such as passwords. RODC installation
media can be created either on an RODC or on a writeable domain controller. In contrast, writeable domain
controller installation media is required to install a writeable domain controller. Writeable domain controller
installation media is created only on a writeable domain controller.
During AD DS installation wizard, AD data can be replicated from the media created previously.
