For a WLAN that requires users to enter a passphrase and supports 802.11r, the correct configuration is FT PSK (Fast Transition Pre-Shared Key) along with Fast Transition. This setup allows for quick and secure roaming between access points within the same WLAN, reducing the time it takes for re-authentication and maintaining a seamless user experience.
