CompTIA A+ Core 2 (220-1002) — Question 313

Which of the following uses a remote access server to forward a user's logon password to an authentication server, allowing or denying access to a system?

Answer options

• A. WPA2-PSK
• B. AES
• C. TACACS
• D. TKIP

Correct answer: C

Explanation

TACACS is designed specifically to handle authentication requests and can forward logon credentials to an authentication server. In contrast, WPA2-PSK and TKIP are related to wireless security protocols, and AES is a symmetric encryption standard, making them unsuitable for the described functionality.
