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.
