{"question_number": 10, "question": "A hardware technician is installing 19 1U servers in a 42-unit rack. The technician needs to allocate enough space per server for optimal air flow. Which of the following unit sizes should be allocated per server?", "correct_answer": "A", "correct_answer_text": "1U", "explanation": "Each 1U server occupies exactly 1U of rack space by definition (1U = 1.75 inches). Installing 19 × 1U servers consumes 19U of the 42U rack, leaving 23U available. In a properly designed rack with hot/cold aisle containment and blanking panels filling all unused spaces, 1U servers do not require additional empty U space between them for airflow - the servers' front-to-back airflow design handles cooling at 1U density. Allocating 2U, 3U, or 4U per server would be wasteful and is not the standard practice for 1U form-factor equipment. The key to optimal airflow is using blanking panels in unused rack spaces (in the remaining 23U), not artificially spacing out the servers themselves.", "generated_by": "claude-sonnet", "llm_judge_score": 3}
