Explanation
{"question_number": 4, "correct_answer": "A, C", "explanation": "DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication policy framework that builds on two existing mechanisms: SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail). SPF validates that the sending mail server's IP is authorized to send on behalf of a domain (via DNS TXT records). DKIM validates message integrity and origin using a cryptographic signature. DMARC ties these together by requiring that at least one of them passes and that the domain is properly aligned, then specifies what action to take on failures (none, quarantine, or reject) and enables reporting.", "generated_by": "claude-sonnet", "llm_judge_score": 3}
