CompTIA Network+ Question A-14

The RAID controller on a server failed and was replaced with a different brand. Which of the following will be needed after the server has been rebuilt and joined to the domain?

A. Vendor documentation
B. Recent backups
C. Physical IP address

Correct Answer: B

Explanation:
If the RAID controller fails and is replaced with a RAID controller with a different brand the RAID will break. We would have to rebuild a new RAID disk, access and restore the most recent backup to the new RAID disk.
Note: RAID controller is a hardware device or software program used to manage hard disk drives (HDDs) or solid-state drives (SSDs) in a computer or storage array so they work as a logical unit. In hardware-based RAID, a physical controller is used to manage the RAID array.
