A router has been configured with the settings shown below: [edit] user@host# show system authentication-order authentication-order [ radius tacplus ]; The router also has a local database that contains the user lab with password lab123. Suppose a user enters the username lab and the password lab123.
What would happen if both the RADIUS and the TACACS servers are not accessible?

A. B. C. D.B
The configuration setting shown indicates that the router will attempt to authenticate users using RADIUS and TACACS+ protocols in that order. If both authentication servers are not accessible, the router will fall back to using the local database for authentication.
In this scenario, the user lab attempts to log in with the password lab123. Since the RADIUS and TACACS+ servers are not accessible, the router will check the local database for a user with the name lab and the matching password. If the user and password match, the user will be authenticated, and the login will be successful.
Therefore, the correct answer is B. The user lab will be authenticated against the local database and will be able to login.
