Explanation

{"question_number": 8, "correct_answer": "C", "explanation": "The hostnamectl set-hostname Comptia-WebNode -H [email protected] command sets the hostname 'Comptia-WebNode' on the remote web server at 192.168.2.14. The -H (or --host) flag tells hostnamectl to perform the operation on a remote machine via SSH, which is exactly what is needed to tag a remote web server. Option A (hostnamectl status) only displays current hostname info and makes no changes. Option B sets a hostname of 86 repeated 'A' characters, which is impractical and likely invalid. Option D uses --transient, which sets a temporary hostname that is lost on reboot - not a persistent configuration.", "generated_by": "claude-sonnet", "llm_judge_score": 2}
