Hi Murat87,
authentication-scheme
authorization-scheme
accounting scheme
When the authentication scheme is default, local authentication is used.
When the authorization scheme is default, local authorization is used.
When the accounting scheme is default, no accounting is used.
Therefore, B is right and D is wrong.

The local-user service-type telnet command to sets the access type for a Telnet user. Therefore, C is wrong.

The local-user Huawei privilege level 0 command is used to set the level of Huawei to 0, and the level of the display current-configuration command is 3. For low-level users, high-level commands cannot be used.
You can refer to https://support.huawei.com/hedex/hdx.do?docid=EDOC1000085855&id=dc_cfg_cli_0008&lang=en and https://support.huawei.com/hedex/hdx.do?docid=EDOC1000085855&id=display_current-configuration&lang=en. Therefore, A is wrong.
I hope it helps!
