Your network contains an Active Directory domain named contoso.com. The domain contains a domain controller named DC1 that runs Windows Server 2012 R2. DC1 is backed up daily.
The domain has the Active Directory Recycle Bin enabled.
During routine maintenance, you delete 500 inactive user accounts and 100 inactive groups. One of the deleted groups is named Group1. Some of the deleted user accounts are members of some of the deleted groups.
For documentation purposes, you must provide a list of the members of Group1 before the group was deleted.
You need to identify the names of the users who were members of Group1 prior to its deletion. You want to achieve this goal by using the minimum amount of administrative effort.
What should you do first?
A . Reactivate the tombstone of Group1.
B . Use the Recycle Bin to restore Group1.
C . Perform an authoritative restore of Group1.
D . Mount the most recent Active Directory backup.
Answer: D
Explanation:
You can use the Active Directory database mounting tool (Dsamain.exe) and a Lightweight Directory Access Protocol (LDAP) tool, such as Ldp.exe or Active Directory Users and Computers, to identify which backup has the last safe state of the forest. The Active Directory database mounting tool, which is included in Windows Server 2008 and later Windows Server operating systems, exposes Active Directory data that is stored in backups or snapshots as an LDAP server. Then, you can use an LDAP tool to browse the data. This approach has the advantage of not requiring you to restart any DC in Directory Services Restore Mode (DSRM) to examine the contents of the backup of AD DS.
