Explanation

{"question_number": 1, "question": "What is the purpose of a MAC address on a network device?", "correct_answer": "C", "explanation": "A MAC (Media Access Control) address is a unique hardware address burned into the network interface card (NIC) by the manufacturer. It operates at Layer 2 (Data Link) of the OSI model and uniquely identifies the physical network interface. Option A is incorrect because 'network address' implies logical addressing (like IP), not hardware. Option B is wrong because MAC addresses are not assigned by DHCP - DHCP assigns IP addresses. Option D is wrong because MAC addresses are assigned by the manufacturer, not a central switch.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
