Which of the following statements are true about WPA?

WPA stands for Wi-Fi Protected Access. It is a wireless security standard. It provides better security than WEP (Wired Equivalent Protection). Windows Vista supports both WPA-PSK and WPA-EAP. Each of these is described as follows: WPA-PSK: PSK stands for Preshared key. This standard is meant for home environment. WPA-PSK requires a user to enter an 8- character to 63-character passphrase into a wireless client. The WPA converts the passphrase into a 256-bit key. WPA-EAP: EAP stands for Extensible Authentication Protocol. This standard relies on a back-end server that runs Remote Authentication Dial-In User Service for user authentication. Note: Windows Vista supports a user to use a smart card to connect to a WPA-EAP protected network. Shared-key WPA is vulnerable to password cracking attacks if a weak passphrase is used. To protect against a brute force attack, a truly random passphrase of 13 characters (selected from the set of 95 permitted characters) is probably sufficient.
