An organization's change-management policy states that any modification to production servers must be preceded by actions in the documented backup plan. You are preparing to replace the RAID controller firmware on a file server that hosts critical data. Which step would best satisfy the backup plan requirement before the maintenance window begins?
Perform a test restore from the most recent full backup to confirm data integrity.
Notify users two hours before downtime to set expectations.
Label the maintenance ticket as a standard change to expedite approval.
Place the server in a sandbox network segment to isolate it during the upgrade.
A backup plan does more than schedule when data is copied; it also calls for confirmation that the data can be successfully recovered. Performing a test restore from the most recent full backup proves the backup's integrity and demonstrates that the organization can return the server to its previous state if the firmware upgrade fails. Relabeling the ticket, notifying users, or isolating the server may be useful change-management tasks, but they do not verify that a usable backup exists.
