Explanation

{"question_number": 8, "question": "What is the result of this idle-time 3 command on a TACACS server configuration?", "correct_answer": "C", "explanation": "The 'idle-time' parameter in the 'tacacs-server host ... test ... idle-time' command specifies the interval, in minutes, at which NX-OS will proactively send test packets to the TACACS+ server to verify it is still reachable and responsive. With 'idle-time 3', the switch sends a test authentication request to 10.10.1.1 every 3 minutes using the specified test username and password. This is a server health-monitoring feature that helps the switch detect a failed TACACS+ server before any real user attempts to authenticate, allowing faster failover to a backup server. It does not log out users, remove the server, or measure hours/days - it monitors availability at a 3-minute polling interval.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
