You are working as an enterprise administrator at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers on the Domain.com network run Windows Server 2008.
An Organizational unit (OU), on a domain controller, was by mistake deleted by a junior enterprise administrator. The best option for you is to use a non-authoritative restore before an authoritative restore of the OU. You need to perform a non-authoritative restore of Active Directory Domain Services (AD DS) without disrupting the other data stored on domain controller.
What should you do?
A.
The best option is to backup of all the volumes.
B.
The best option is to use a Critical volume backup.
C.
The best option is to backup of the volume that hosts Operating system.
D.
The best option is to backup of AD DS folders.
Explanation:
If you do not want to disrupt the data stored on domain controller, you need to use a critical volume backup to perform non-authoritative restore of AD DS. You must first complete a non-authoritative restore before performing an authoritative restore of AD DS. You must ensure that the replication does not occur after non-authoritative restore. You must do a critical-volume backup before you perform a non-authoritative restore. To prevent the replication from occurring after the non-authoritative and to perform the authoritative restore portion of the operation, you must restart the domain controller in Directory Services Restore Mode and perform the authoritative restore at the domain controller that you are restoring. You should start the domain controller normally after performing the authoritative restore of AD DS. You should also synchronize replication with all replication partners.
