CompTIA A+ Core 2 (220-1002) — Question 120

A large corporation wants to secure its wireless network so only employees can connect. Which of the following technologies should be used to control access by user account?

Answer options

• A. RADIUS
• B. WPA2
• C. TKIP
• D. AES

Correct answer: A

Explanation

RADIUS is the correct choice as it provides centralized authentication, authorization, and accounting for users connecting to the network. WPA2 improves wireless security but does not specifically manage user access. TKIP and AES are encryption protocols and do not handle user account controls.
