A - https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/cns/configuration/xe-16-6/cns-xe-16-6-book/netconf-sshv2.html NETCONF over SSHv2 is a different requirement with different commands to enabling traditional NETCONF. The question asks you to enable NETCONF over SSH, and NETCONF with YANG. netconf ssh - Enables NETCONF over SSH (netconf-yang is not required) Terminal line configuration is mandatory - NETCONF over SSHv2 requires that a vty line be available for each NETCONF session as specified in the netconf max-session command (default = 5 if not explicitly configured) Bit of a brutal question really

In option A, the command netconf-yang is missing

Providing Privilege Access to Use NETCONF To start working with NETCONF APIs, you must be a user with privilege level 15. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/prog/configuration/1612/b_1612_programmability_cg/configuring_yang_datamodel.html

Segun buenaspracticas la B: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/prog/configuration/173/b_173_programmability_cg/configuring_yang_datamodel.html

Correct answer is A. B is missing terminal lines configuration

The answer is A. The question is asking to configure NETCONF via SSHv2. >SSH needs to be configured (prerequisite) >Between 4 and 16 VTY lines (mandatory) >The AAA commands and netconf-yang commands are not necessary since this question is only asking for SSHv2, not NETCONF in general (see link). >Username and password with privilege level 15 (mandatory)

Answer is B, not because the configuration has AAA, but because the configuration has: router(config)#netconf ssh -> Enabling netconf on the SSH router(config)#netconf-yang -> Enabling the protocol and starts the services

ip ssh version 2 #enable SSH netconf ssh #enable NETCONF over SSH

I think it's A https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/cns/configuration/xe-16-7/cns-xe-16-7-book/netconf-sshv2.pdf

correct answer is C
