{"question_number": 9, "question": "A Linux administrator needs to know the MAC address of the server's gateway. Which of the following commands should the administrator run to obtain this information?", "correct_answer": "B", "explanation": "arp -a displays the current ARP (Address Resolution Protocol) cache, which maps known IP addresses to their corresponding MAC addresses. After the server communicates with its gateway, the gateway's IP-to-MAC mapping will appear in the ARP table, revealing the gateway's MAC address. The options arp -gw, arp -gwi, and arp -gtw are not valid arp command flags. The -a flag is the standard option to display all cached ARP entries.", "generated_by": "claude-sonnet", "llm_judge_score": 3}
