350-501 Question #531: Real Exam Question with Answer & Explanation

Question

Network devices in the core layer use different iGPs, and the network is split into several areas. The engineer must use a NETCONF operation to toad a full interface configuration on multiple Cisco devices to ensure that they meet company standards. The devices must work over SSH from the Linux jump server. Which action meets the configuration requirements?

Options

• AUse the NETCONF operation <get-update> to load the configuration and verify that TCP port 830
• BUse the NETCONF operation <get-update> to load the configuration and verify that TCP port 22
• CUse the NETCONF operation <get-config> to load the configuration and verify that TCP port 22 is
• DUse the NETCONF operation <get-config> to load the configuration and verify that TCP port 830

Explanation

{"question_number": 1, "correct_answer": "D", "explanation": "NETCONF (Network Configuration Protocol) uses TCP port 830 by default when transported over SSH, as defined in RFC 6242. This is distinct from standard SSH on TCP port 22. The correct NETCONF operation here is <get-config>, which is a standard NETCONF RPC used to retrieve the full or partial configuration datastore from a managed device (e.g., the running, startup, or candidate datastore). '<get-update>' is not a valid NETCONF operation and is a distractor. Since the engineer needs to retrieve and verify interface configurations across multiple Cisco devices via NETCONF over SSH, the correct pairing is <get-config> on TCP port 830. Options A and B are eliminated because <get-update> does not exist in the NETCONF RFC 6241 specification. Option C is eliminated because standard SSH port 22 is not used for NETCONF sessions (port 830 is the IANA-assigned port for NETCONF over SSH).", "generated_by": "claude-sonnet", "llm_judge_score": 4}
