The correct answer is B. Authentication, Authorization, and Accounting. HPE Aruba Networking AOS-CX documentation defines AAA as the security framework used to manage user access, enforce privileges, and log user access records. Authentication identifies users and validates their credentials. Authorization determines what authenticated users are allowed to do, such as which commands or services they can access.
Accounting records user activity, access events, or resource usage for auditing and tracking. AAA can use local user accounts or remote authentication services such as RADIUS and TACACS+, depending on the switch configuration and security design. Option A is incorrect because AAA does not stand for Aruba Authentication Algorithm. Option C is not the correct expansion of the acronym. Option D uses similar- sounding terms but is not the official meaning. In HPE Aruba Networking documentation, AAA means Authentication, Authorization, and Accounting.
