CompTIA Server+ SK0-005 Practice Question
During a scheduled maintenance window, a systems administrator attempted to apply a UEFI firmware update to a 1U rack server. Part-way through the flash, an unexpected power outage occurred. When power is restored, POST reports:
"Current System ROM is corrupt … now booting redundant System ROM."
The OS boot volume is still healthy, and business services need to come back online as quickly as possible. Which of the following actions should the administrator perform NEXT to return the server to its approved firmware baseline while keeping downtime to a minimum?
Boot from the backup ROM image and re-flash the vendor-approved firmware from the ROM-based setup utility.
Disconnect all production drives, boot to a rescue ISO, and perform a low-level format before reinstalling firmware.
Clear the CMOS settings with the maintenance switch, then reinstall the operating system from backup.
Replace the system board to obtain a new, factory-programmed ROM chip.
