Question

Which of the following approaches to wireless LAN (WLAN) security involves the use of an authentication server?

a) WEP (Wired Equivalent Privacy)
b) WPA (Wi-Fi Protected Access)
c) MAC filtering
d) SSID hiding

Answer 1

WPA (Wi-Fi Protected Access) is the WLAN security approach that uses an authentication server for securing wireless networks.

Step-by-step explanation:

The approach to wireless LAN (WLAN) security that involves the use of an authentication server is Wi-Fi Protected Access (WPA). WEP (Wired Equivalent Privacy) uses a set key for encrypting traffic, which does not involve an authentication server. MAC filtering works by allowing or denying devices based on their hardware addresses and does not use an authentication server. SSID hiding is the process of not broadcasting the wireless network name to devices, which also does not involve authentication servers.
