Q

Which of the following acronyms refers to a client authentication method used in WPA2 Personal mode?

A

PSK.

WPA2 Personal Mode uses AES and a PSK for authentication. WPA2 Personal Mode is more secure than WPA and WEP however, it is less secure than WPA2 Enterprise mode which uses more complex authentication.
