Explanation
{"question_number": 6, "correct_answer": "A", "explanation": "YANG models used with NETCONF fall into several categories. When a feature is specific to a particular vendor's OS - in this case, Cisco NX-OS - the engineer must use the Native model (A). Cisco Native YANG models are developed and maintained by Cisco and expose device-specific features, configurations, and operational data that are unique to Cisco platforms such as NX-OS or IOS-XE. These models cover capabilities not defined in any standards body. IETF models (D) are defined in RFCs and cover common networking constructs (interfaces, routing, etc.) in a vendor-neutral way. OpenConfig models (C) are defined by a vendor-neutral consortium focused on operational use cases. IEEE models (B) cover specific IEEE standards. None of these standard models would include NX-OS-specific features.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
