Which of the following is the most secure protocol used for encryption in a wireless network?

A.
WPA2

B.
WPA

C.
WEP

D.
IPSec

Explanation:
Among the given choices, WPA2 is the most secure wireless protocol used in a wireless network. This protocol was created in response to several serious weaknesses researchers had found in the previous system, Wired Equivalent Privacy (WEP). WPA2 is an updated version of WPA.This standard is also known as IEEE 802.11i. WPA2 offers enhanced protection to wireless networks than WPA andWEP standards. It is also available as WPA2-PSK and WPA2-EAP for home and enterprise environment respectively.

Answer C and B are incorrect. Although these two protocols are also used for encryption in a wireless network, they are less secure than WPA2.

Answer D is incorrect. IPSec is not used for wireless encryption.
