Trusted Agent (TA) Practice Test

Which statement best explains AAA in a TA context?

Authentication verifies identity; Authorization grants access rights; Accounting records activity for auditing. Authentication encrypts data; Authorization logs keystrokes; Accounting hides audit logs. Authentication skips user verification; Authorization overrides policies; Accounting replaces attestations. Authentication manages keys; Authorization handles network routing; Accounting handles user training.

Correct Answer:

Authentication verifies identity; Authorization grants access rights; Accounting records activity for auditing.

Explanation:

AAA in a TA context focuses on three functions: Authentication confirms who is trying to access resources, Authorization determines what that user is allowed to do, and Accounting records the actions taken for auditing and accountability. The statement that Authentication verifies identity, Authorization grants access rights, and Accounting records activity for auditing directly maps to these three roles, making it the best explanation of AAA. Other options mix in concepts that aren’t part of AAA, such as encryption or keystroke logging, or suggest actions like skipping verification or hiding audit logs, which don’t describe the AAA framework.
