Refer to the exhibit. An engineer deploys a script to retrieve the running configuration from a NETCONF-capable Cisco IOS XE device that is configured with default settings. The script fails. Which configuration must be applied to retrieve the configuration using NETCONF?
The default port for NETCONF communication is 830. By changing the port in the script to 830, the connection to the NETCONF-capable Cisco IOS XE device should work correctly. NETCONF typically uses port 830 for secure communication over SSH, while port 22 is typically used for standard SSH connections without NETCONF.
B. port=830 NETCONF typically uses port 830 for communication.
B is correct. Typical defaults for a NETCONF-capable Cisco IOS XE device: XML as the data encoding format. Port 830 for NETCONF communication. The "admin" user for authentication by default. SSH as the transport protocol for secure communication.
why it is not A?
As per Cisco, Netconf uses SSH but defaults to port number 830 https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/prog/configuration/1612/b_1612_programmability_cg/configuring_yang_datamodel.pdf NETCONFuses a simple RemoteProcedure Call (RPC) based mechanism to facilitate communication between a client and a server. The client can be a script or application running as part of a network manager. The server istypically a network device (switch or router). It usesSecureShell (SSH) asthe transport layer across network devices. It uses SSH port number 830 as the default port. The port number is a configurable option.
