Which of the following wireless protocols could be vulnerable to a brute-force password attack? (Choose two.)

A.
WPA2-PSK

B.
WPA – EAP – TLS

C.
WPA2-CCMP

D.
WPA -CCMP

E.
WPA – LEAP

F.
WEP

Explanation:
A brute force attack is an attack that attempts to guess a password. WPA2-PSK and WEP both use a “PreShared Key”. The pre-shared key is a password and therefore is susceptible to a brute force attack.
