Why each option

This question identifies the three core security services represented by the acronym AAA.

AauthorizationCorrect

Authorization determines what a user is permitted to do or access after their identity has been verified.

BaccountingCorrect

Accounting tracks user activity, including what services they accessed, how long, and how many resources were consumed.

CauthenticationCorrect

Authentication verifies the identity of a user or device, typically through credentials like a username and password.

Daccountability

Accountability is a broader concept related to tracking actions, but it is achieved through accounting and is not one of the explicit 'A's in the AAA acronym.

Eaccessibility

Accessibility refers to the ability to access a system, which AAA helps manage, but it is not one of the 'A's in the acronym.

Fauthority

Authority relates to authorization, granting permissions, but is not one of the specific 'A's in the AAA acronym itself.
