[RTA]aaa
[RTA-aaa]domain huawei
[RTA-aaa-domain-huawei]authentication-scheme au1
[RTA-aaa-domain-huawei]authentication-scheme au2

Answer options

• A. The authentication scheme au2 is used for authentication. If the authentication scheme au2 is deleted, the authentication scheme au1 is used.
• B. The authentication scheme au1 is used for authentication.
• C. The authentication scheme au1 is used for authentication. If the authentication scheme au1 is deleted, the authentication scheme au2 is used.
• D. The authentication scheme au2 is used for authentication.

Correct answer: A

Explanation

The correct answer is A because the configuration indicates that au2 is the primary authentication scheme. If au2 is deleted, the system will revert to au1 for authentication. Options B and C incorrectly assert the primary role of au1, while D incorrectly states that au2 is the only scheme used.
