Correct Answers: A
When a domain contains more than one domain controller, Active Directory replicates directory objects, such as users, groups, organizational units, and computers, to all the domain comtrollers in that domain. When you are restoring a domain controller by using backup and restore programs, such as Ntbackup or those from third-party providers, the default mode for the restore is nonauthoritative. This means that the restored server is brought up-to-date with its replicas through the normal replication mechanism. For example, if a domain controller is restored from a backup tape that is two weeks old, when you restart it, the normal replication mechanism brings it up-to-date with respect to its replication partners.
Authoritative restore allows the administrator to recover a domain controller, restore it to a specific point in time, and mark objects in Active Directory as being authoritative with respect to their replication partners. For example, you might need to perform an authoritative restore if an administrator inadvertently deletes an organizational unit containing a large number of users. If you restore the server from tape, the normal replication process would not restore the inadvertently deleted OU. Authoritative restore allows you to mark the OU as authoritative and force the replication process to restore it to all of the other domain controllers in the domain. |
