The correct answer is A. RAID 0. RAID 0 uses striping with no redundancy, so a single failing drive causes random data corruption across the array with no fault tolerance.
Question
A technician is working on a PC that utilizes a RAID array for operation. The user of the system has reported that random files are becoming corrupted on creation with no pattern to the activity. One drive in the array is likely failing and causing the read/write failures. Which of the following types of RAID is MOST likely in use?
Options
- ARAID 0
- BRAID 1
- CRAID 5
- DRAID 10

Why each option
RAID 0 uses striping with no redundancy, so a single failing drive causes random data corruption across the array with no fault tolerance.
RAID 0 stripes data across multiple drives to improve performance but provides zero redundancy - there is no parity or mirroring. When one drive begins to fail, read/write operations to stripes on that drive fail unpredictably, producing random file corruption with no recoverable fallback, which matches the described symptom exactly.
RAID 1 mirrors data across two drives, so a single drive failure does not corrupt files - the mirror continues to serve data intact.
RAID 5 uses distributed parity across three or more drives and can survive one drive failure without data loss or corruption.
RAID 10 combines mirroring and striping and can tolerate at least one drive failure per mirrored pair without causing file corruption.
