Huawei devices support different authentication modes:
authentication-mode local: Requires a username and password stored locally.
authentication-mode hwtacacs: Uses Huawei TACACS+ authentication, which requires a username and password.
authorization-mode hwtacacs: Refers to authorization (not authentication).
authentication-mode none:Does not require a username or password, meaning no authentication is needed.
Thus, the correct answer is D.
