Which command should be used to configure a vty line to use the aaaservers authentication method list?
- authentication aaaservers
- line authentication aaaservers
- login authentication aaaserver
- authentication method aaaservers
Explanation: To configure a vty line to use a specifically named AAA authentication method list, you must use the login authentication command followed by the name of the list.
While a default method list is automatically applied to all lines and interfaces, any named method list must be explicitly applied in line configuration mode to take effect. Once this command is issued on a vty line (e.g., line vty 0 4), the named list overrides the default authentication settings for that specific line. This architectural framework allows administrators to enforce different security policies for different access methods, such as requiring a more secure server group for remote network access while maintaining a local backup for physical console access.
