CompTIA Network+ (N10-007) — Question 252

A network technician attempts to limit access to a wireless network by using WPA2 and a pre-shared key; however, employees have been sharing this key with others. Which of the following methods should the technician configure on the wireless access point to ensure only corporate systems can connect using the least amount of effort?

Answer options

• A. RADIUS
• B. EAP-TLS
• C. Port security
• D. MAC filtering

Correct answer: D

Explanation

MAC filtering allows the technician to specify which devices can connect to the network based on their MAC addresses, making it a straightforward solution to restrict access. RADIUS and EAP-TLS are more complex authentication methods that require additional infrastructure, while port security is typically used in wired networks rather than wireless ones.
