CompTIA A+ Core 2 (220-1002) — Question 469

Which of the following technologies can be utilized in a wireless network environment to provide secure SSO access for WiFi and network resources?

Answer options

• A. WPA2
• B. AES
• C. MAC filtering
• D. RADIUS
• E. WPS

Correct answer: D

Explanation

RADIUS is the correct answer as it provides centralized authentication, authorization, and accounting for users accessing network resources, including WiFi. WPA2 and AES are encryption protocols that enhance security but do not manage user authentication. MAC filtering adds a layer of security by allowing only specific devices but does not facilitate SSO. WPS is a method for simplifying the connection process but does not offer secure SSO access.
