Disabling which of the following would make wireless local area networks more secure against unauthorized access?

A. MAC (Media Access Control) address filtering
B. WPA (Wi-Fi Protected Access Protocol)
C. LEAP (Lightweight Extensible Authentication Protocol)
D. SSID (service set identifier) broadcasting

Correct Answer: D

Explanation:

Explanation:
Disabling SSID broadcasting adds security by making it more difficult for unauthorized users to find the name of the access point. Disabling MAC address filtering would reduce security. Using MAC filtering makes it more difficult to access a WLAN, because it would be necessary to catch traffic and forge the MAC address. Disabling WPA reduces security. Using WPA adds security by encrypting the traffic. Disabling LEAP reduces security. Using LEAP adds security by encrypting the wireless traffic.
