CompTIA Network+ (N10-007) — Question 263

A network administrator is securing the wireless network in a multitenant building. The network uses a passphrase for authentication so it is easy to allow guests onto the wireless network, but management would like to prevent users from outside the office space from accessing the network. Which of the following security mechanisms would BEST meet this requirement?

Answer options

• A. MAC filtering
• B. WPA-PSK
• C. 802.1X
• D. Geofencing

Correct answer: D

Explanation

Geofencing is the most suitable option as it allows the network to restrict access based on geographical boundaries, ensuring only users within the designated area can connect. MAC filtering, WPA-PSK, and 802.1X do not inherently provide location-based access control, making them less effective for this specific requirement.
