Which command would you use to re-align a SnapMirror relationship after reverting using an older snapshot?

• A. SnapMirror resync
• B. SnapMirror initialize
• C. SnapMirror update
• D. SnapMirror quiesce

Answer: (A)

When you revert the destination to an older snapshot, its data can diverge from the source. The resync operation refreshes the SnapMirror relationship so the destination is brought back to exactly mirror the source’s current state. This directly re-aligns the two sides after a revert. Initializing would re-create or re-baseline the relationship, which isn’t what you need after already having a relationship. Updating would only apply recent changes and may not fully correct the divergence caused by the revert. Quiescing just pauses replication for maintenance, not re-aligning data. So the resync command is the correct choice.
