220-802 Question #846: Real Exam Question with Answer & Explanation
The correct answer is B: Reformat both drives and reload windows. RAID 0 has no redundancy, so a failure corrupts all striped data across both drives. Reformatting both drives and reloading Windows is the most cost-effective recovery path.
Question
Joe, a technician, recently built a new gaming PC for Ann, a customer, with two hard drives configured in RAID 0. Ann calls and states she was playing a game online and the computer shut off. Now the computer will not boot. Which of the following is a cost effective way to correct the issue?
Options
- ARemove both drives from the RAID array
- BReformat both drives and reload windows
- CReplace both of the drives and load windows
- DReplace one of the drives and rebuild the array
Explanation
RAID 0 has no redundancy, so a failure corrupts all striped data across both drives. Reformatting both drives and reloading Windows is the most cost-effective recovery path.
Common mistakes.
- A. Removing the drives from the array without reformatting does not fix the corrupted or lost data that caused the boot failure.
- C. Replacing both drives is expensive and unnecessary if the existing drives are physically healthy - a software/data issue does not require new hardware.
- D. RAID 0 has no parity and cannot be rebuilt by replacing a single drive; rebuilding is only possible with RAID levels that include redundancy such as RAID 1 or RAID 5.
Concept tested. RAID 0 failure recovery and cost-effective remediation
