You have a wireless access point that is configured to use Advanced Encryption Standard (AES) security.

A pre- shared key is not configured on the wireless access point.

You need to connect a computer that runs Windows 7 to the wireless access point.

Which security setting should you select for the wireless connection?

A.
802.1x

B.
WPA-Personal

C.
WPA2-Enterprise

D.
WPA2-Personal

Explanation:
WPA and WPA2 indicate compliance with the security protocol created by the Wi-Fi Alliance to secure wireless computer networks. WPA2 enhances WPA, which in turn addresses weaknesses in the previous system, WEP. WPA was intended as an intermediate measure to take the place of WEP while an IEEE 802.11i standard was prepared. 802.1X provides port-based authentication, which involves communications between a supplicant (a client computer), an authenticator (a wired Ethernet switch or WAP), and an authentication server (typically a Remote Authentication Dial In User Service, or RADIUS, server).

WPA2-Enterprise
WPA-Enterprise and WPA2-Enterprise authenticate through the Extensible Authentication Protocol (EAP) and require computer security certificates rather than PSKs. The following EAP types are included in the certification program:

* EAP-TLS
* EAP-TTLS/MSCHAPv2
* PEAPv0/EAP-MSCHAPv2
* PEAPv1/EAP-GTC
* EAP-SIM

If you want to use AES and to use computer certificates rather than a PSK, you would choose WPA2-Enterprise.

WPA2-Personal
If you have a small network that is not in a domain and cannot access a CA server, but you install a modern WAP that supports AES, you would use WPA2-Personal (with a PSK).

WPA-Personal
If you have a small network that is not in a domain and cannot access a CA server and your WAP does not support AES, you would use WPA-Personal.

802.1x
If you have a RADIUS server on your network to act as an authentication server and you want the highest possible level of security, you would choose 802.1X.
