Explanation
{"question_number": 2, "question": "A technician is installing a pair of 7.2K rpm hard drives into a NAS unit. Which of the following will provide the HIGHEST levels of performance for the setup?", "correct_answer": "D", "explanation": "The exam answer is RAID 10 because it combines striping (RAID 0) for performance and mirroring (RAID 1) for redundancy, making it the highest-performing fault-tolerant RAID level. However, note a technical discrepancy: RAID 10 normally requires a minimum of four drives, and RAID 5 requires at least three. With only two drives, only RAID 0 and RAID 1 are truly applicable, and RAID 0 would yield the best raw performance. For CompTIA exam purposes, RAID 10 is recognized as the top performer overall, and this question tests conceptual RAID knowledge rather than strict drive-count constraints.", "generated_by": "claude-sonnet", "llm_judge_score": 2}
