Explanation

Option A is correct because it takes the minimum necessary action: adding the missing PWWN (:11:11:11:11:11:11:11:13) to the existing zone Server11 and re-activating the zoneset on MDS-A. When a zoneset is activated on one switch in the fabric, Cisco MDS automatically propagates the updated zone database to peer switches (like MDS-B) over the ISL - no manual intervention on the second switch is needed, and existing zoned traffic remains uninterrupted.

Option B is wrong because simply deactivating the zoneset on MDS-A tears down all active storage paths in that zoneset - this is the most disruptive action possible and doesn't fix anything by itself. Option C is wrong because it likely includes an unnecessary additional step (such as deactivating the zoneset first or reconfiguring MDS-B) that introduces extra disruption beyond what A requires. Option D is wrong because zoneset import pulls a peer switch's active zoneset into the local database - it doesn't resolve a missing PWWN, and the correct workflow is to make changes on MDS-A and activate outward, not import from MDS-B.

Memory tip: In Cisco MDS zoning, think "Add then Activate" - always make the smallest zone database change needed and activate on the managing switch; the fabric handles propagation automatically. If you see "deactivate" or "import from peer" as the first step, that's usually the wrong answer.
