Refer to the exhibit. An engineer tries to log in to router R1. Which configuration enables a successful login?
The correct answer is C. R1#netconf-yang. Assuming the login attempt refers to programmatic access via NETCONF/YANG, the netconf-yang command enables the necessary protocols for this type of session.

Why each option
Assuming the login attempt refers to programmatic access via NETCONF/YANG, the `netconf-yang` command enables the necessary protocols for this type of session.
This command is incomplete as it lacks a password or secret for the username, preventing successful local user authentication for CLI login.
This command is incomplete as it lacks a password or secret for the username, preventing successful local user authentication for CLI login.
The `netconf-yang` command enables NETCONF and YANG on the router, which are protocols used for programmatic access and configuration management. If the 'login' refers to a client attempting to establish a NETCONF session, this command is essential to enable the service.
While `aaa new-model` enables AAA services, it doesn't, by itself, enable a successful login without further configuration of authentication methods (e.g., local database or TACACS+/RADIUS).
