Which of the following may significantly reduce data loss if multiple drives fail at the same time?
The correct answer is B. RAID. RAID (Redundant Array of Independent Disks) is a storage technology that combines multiple physical drives to provide redundancy and/or improved performance. Certain RAID levels (e.g., RAID 5, RAID 6, RAID 10) can tolerate one or more simultaneous drive failures without data…

Explanation
RAID (Redundant Array of Independent Disks) is a storage technology that combines multiple physical drives to provide redundancy and/or improved performance. Certain RAID levels (e.g., RAID 5, RAID 6, RAID 10) can tolerate one or more simultaneous drive failures without data loss by using parity data or mirroring. Virtualization abstracts compute resources but does not inherently protect against drive failure. Load balancing distributes network or application traffic and is unrelated to drive redundancy. Server clustering provides high availability at the server level but does not directly protect against simultaneous multi-drive failure the way RAID does.
