The authentication order configuration on your M120 includes the settings tacplus and radius (in that order), but does not include the password parameter. You attempt to log in to the device, but the network containing the authentication servers is currently down.

A. B. C. D.C
The authentication order configuration on the M120 device includes the settings tacplus and radius (in that order) but does not include the password parameter. This means that the device will attempt to authenticate the user against the TACACS+ server first, and if that fails, it will attempt to authenticate against the RADIUS server.
In this scenario, the network containing the authentication servers is currently down, which means that the device cannot communicate with either the TACACS+ or RADIUS server. As a result, the device will not be able to authenticate the user using either of these external authentication methods.
Option A: The login attempt is rejected - This option is incorrect because the device will not immediately reject the login attempt.
Option B: The login attempt is automatically accepted after the authentication servers timeout value is reached, since there are no other authentication methods available - This option is incorrect because the device will not automatically accept the login attempt after the authentication servers timeout value is reached. The device will continue to wait for a response from the authentication servers until the timeout value is reached.
Option C: The M120 automatically tries authenticating locally on the device after the authentication servers' timeout value is reached - This option is also incorrect because the M120 device does not have a local authentication method configured.
Option D: The M120 automatically tries authenticating locally on the device before using external authentication - This is the correct option. If the authentication servers are not available, the M120 device will attempt to authenticate the user using the local authentication database. If the local authentication is successful, the user will be logged in to the device. If the local authentication fails, the user will not be able to log in to the device.
Therefore, the correct answer is D: The M120 automatically tries authenticating locally on the device before using external authentication.
