Question 22 - D-PWF-DS-23 discussion

Secure snapshots in PowerFlex are controlled by policies that define their retention and expiration periods. If a snapshot has a lock enabled, it cannot be deleted until the lock is disabled. The lock is a security feature that prevents accidental or unauthorized deletion of the snapshot before its intended retention period1.

To delete a secure snapshot that is still within its expiration period but needs to be removed, the administrator must first disable the snapshot policy lock. Here are the general steps to do so:

Access PowerFlex Manager.

Navigate to the Snapshots section.

Locate the specific snapshot that needs to be deleted.

Disable the lock on the snapshot policy associated with the snapshot.

Once the lock is disabled, the snapshot can be deleted manually.

Changing the snapshot expiration period to 30 days (Option C) would not affect the ability to delete the snapshot if the lock is still enabled. The Dual Signature Policy agreement with Dell (Option A) is not a standard procedure for deleting snapshots within PowerFlex and is not related to the administrative controls of snapshot policies.

Therefore, the correct answer is B. Disable the snapshot policy lock on the snapshot, as this action will allow the administrator to delete the snapshot before the expiration period, provided that the snapshot is no longer needed and can be safely removed from the system1.
