CompTIA Network+ (N10-007) — Question 345

A network manager has received reports that some employees have been using the company's WiFi to log onto their social media accounts from their personal devices. The network manager is looking for a solution to prevent this type of activity. The Chief Information Officer (CIO) wants to continue using a pre-shared key and add an additional layer of security to allow only authorized users to authenticate to the WiFi. Which of the following solutions would address this request?
(Choose two.)

Answer options

• A. Port security
• B. MAC filtering
• C. Geofencing
• D. 802.1X
• E. Proxy server
• F. SSO

Correct answer: B, D

Explanation

MAC filtering (B) allows the network manager to permit or deny connections based on the MAC addresses of devices, ensuring that only authorized devices can access the WiFi. 802.1X (D) provides network access control and authentication for users, adding a robust layer of security that works well with pre-shared keys. The other options do not specifically address the requirement for user authentication on the WiFi network.
