Explanation
{"question_number": 5, "question": "Which nonproprietary mechanism can be used to automate rendezvous point distribution in a large PIM domain?", "correct_answers": ["B"], "explanation": "BSR (Bootstrap Router) (B) is the standards-based, nonproprietary mechanism for distributing Rendezvous Point (RP) information across a PIM domain, defined in RFC 5059. Candidate-BSRs and Candidate-RPs advertise themselves, and the elected BSR floods RP-set messages to all PIM routers. Auto-RP (C) is a Cisco proprietary mechanism that predates BSR and performs a similar function but is not an open standard. Embedded RP (A) is specific to IPv6 PIM and encodes the RP address within the multicast group address itself - it is not applicable for general large IPv4 PIM domains. Static RP (D) requires manual configuration on every router and does not automate distribution.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
