Why is authentication with AAA preferred over a local database method?

  • It provides a fallback authentication method if the administrator forgets the username or password.
  • It uses less network bandwidth.
  • It specifies a different password for each line or port.
  • It requires a login and password combination on the console, vty lines, and aux ports.

Explanation: The local database method of authentication does not provide a fallback authentication method if an administrator forgets the username or password. Password recovery will be the only option. When authentication with AAA is used, a fallback method can be configured to allow an administrator to use one of many possible backup authentication methods.
