A system administrator is configuring a new storage array for a critical application and selects...

Option B. RAID 3 is the correct answer because the question describes a RAID level that uses byte-level striping with a dedicated parity disk and requires at least three disks . That combination matches RAID 3. CHFI v11 explicitly includes RAID Storage System , RAID and Virtualization , and the broader understanding of storage structures under digital evidence fundamentals, so candidates are expected to recognize RAID types and how they affect evidence acquisition and recovery.

The key clues are the dedicated parity drive and the fact that the system can continue functioning after a single disk failure . RAID 3 is designed to provide fault tolerance for one failed drive by reconstructing data from the remaining striped disks and the parity information. This makes it different from RAID 0 , which has no redundancy, RAID 1 , which mirrors data rather than using dedicated parity, and RAID 10 , which combines striping and mirroring in a different way.

Because the scenario precisely describes byte-level striping plus one parity disk with single-disk fault tolerance, RAID 3 is the only answer that fully fits the described configuration.
