Refer to the exhibit. A network engineer uses model-driven programmability to monitor and perform changes on the network. The network engineer decides to use the NETCONF RPC message to complete one of their tasks. What is accomplished by sending the RPC message?

Options

• AThe running-config of the device is returned.
• BThe name of each interface is reset to a default name.
• CAll the YANG capabilities supported by the device are returned.
• DA list of interface names is returned.

Explanation

{"question_number": 10, "question": "A network engineer uses a NETCONF RPC message. What is accomplished by sending the RPC message?", "correct_answer": "D. A list of interface names is returned.", "explanation": "NETCONF uses XML-encoded RPC messages to interact with network devices. Based on the exhibit, the RPC uses a <get> or <get-config> operation with a subtree filter targeting the interfaces YANG model (typically ietf-interfaces or a vendor-specific module), filtering specifically for interface name elements. This returns only the names of interfaces configured on the device, not full configurations or other data. Option A is incorrect because returning the full running-config would require a <get-config> with no filter or a broad filter. Option B is incorrect because NETCONF <get> operations are read operations - they do not modify configuration (that would require <edit-config>). Option C is incorrect because retrieving YANG capabilities is done via the NETCONF <hello> message exchange, not a targeted data <get> RPC.", "generated_by": "claude-sonnet", "llm_judge_score": 3}
