Which backup option can be used to back up only the critical volumes related to AD DS?

• A. Critical-volumes backup
• B. Select system backup
• C. System state backup
• D. Domain service backup

Answer: (A)

Focusing on the data that AD DS needs to function and be recovered makes the backup fast and efficient. The critical-volumes backup mode selects only the volumes essential for domain controller recovery—typically the boot/system volume and the volume that holds the AD DS data (NTDS.dit) and its logs, plus SYSVOL. By backing just these volumes, you can restore AD DS quickly without pulling in every other nonessential drive. Other options bundle more data than necessary or aren’t targeted to the specific AD DS recovery scenario. A system backup covers more of the OS and installed components, increasing backup size without giving you the leanest restore path for AD DS. A system state backup includes AD DS data but is designed for broader system recovery, not a minimal, AD-centric volume restore. A domain service backup isn’t a standard, targeted option for this scenario.
