Answer: A

Explanation:

Referring to the exhibit, when users attempt to connect to vty lines 0 through 4, the device will authenticate them against TACACS+ if local authentication fails. This configuration shows that AAA new-model is enabled, which allows for the use of TACACS+ for authentication. The configuration also specifies an authorization list for login using TACACS+. If TACACS+ fails, it will revert to local authentication as there’s no explicit deny statement in the configuration.
