{"question_number": 7, "question": "A technician is replacing a failed drive in a RAID 5 array. Which of the following is the first step the technician should take before hot swapping the drive out of the array?", "correct_answer": "D", "correct_answer_text": "Perform a full backup", "explanation": "Although RAID 5 provides fault tolerance for a single drive failure, the array is in a degraded state during that failure. If a second drive fails while the replacement drive is rebuilding, all data is lost. Performing a full backup before any maintenance operation is the most critical first step to protect against data loss. Documentation is good practice but is not the first priority. Shutting down the array is unnecessary since the question specifies hot swapping. Safely disposing of the failed drive is a step that occurs after the replacement, not before.", "generated_by": "claude-sonnet", "llm_judge_score": 3}
