Explanation
{"question_number": 5, "question": "An engineer is assigned to enable MAB (MAC Authentication Bypass) across all access switches in the network.", "correct_answer": "D", "explanation": "The mab command is an interface-level command and must be entered in interface configuration mode (config-if), not global configuration mode. MAB is enabled per-port because it applies to a specific switchport, not to the device globally. The command authentication port-control auto (options A and C) enables 802.1X port-based authentication on an interface but does not enable MAB on its own. MAB requires mab to be configured at the interface level to allow MAC address-based authentication as a fallback or standalone method.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
