CompTIA Security+ (SY0-501) — Question 739

Which of the following is an example of the second A in the AAA model?

Answer options

• A. The encryption protocol successfully completes the handshake and establishes a connection
• B. The one-time password is keyed in, and the login system grants access
• C. The event log records a successful login with a type code that indicates an interactive login
• D. A domain controller confirms membership in the appropriate group

Correct answer: D

Explanation

The correct answer, D, illustrates the 'Authorization' aspect of the AAA model, where a domain controller verifies group membership. Options A and B relate to 'Authentication' since they deal with proving identity, while C pertains to logging and monitoring, which does not directly demonstrate authorization.
