{"question_number": 1, "question": "Email encryption is configured on a Cisco ESA that uses CRES. Which action is taken on a message when CRES is unavailable?", "correct_answer": "A", "explanation": "Cisco Registered Envelope Service (CRES) is a cloud-based service used by the ESA to encrypt outbound email. When CRES is temporarily unavailable, the ESA does not drop the message, send it in cleartext, or hand it off to another appliance. Instead, the message is requeued - held and retried until CRES becomes available again. This preserves both message delivery and the encryption requirement, ensuring sensitive data is never transmitted unprotected.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
