CompTIA A+ Core 2 (220-1002) — Question 466

Which of the following allows for per-command authentication and authorization?

Answer options

• A. TKIP
• B. RADIUS
• C. AES
• D. TACACS

Correct answer: D

Explanation

TACACS is the correct answer because it supports per-command authentication and authorization, allowing fine-grained control over user permissions. In contrast, RADIUS typically handles user authentication and accounting but does not provide detailed command authorization. TKIP and AES are encryption protocols and do not relate to authentication or authorization.
