Suggested Answer: AC 🗳️
In the absence of CCKM, a WPA/WPA2 client must perform a full EAP authentication to a remote AAA/RADIUS server, followed by a WPA/WPA2 4- way handshake whenever it roams. This process can take more than one second. With CCKM, the roaming client and WLC can use pre-established keying material to immediately establish a PTKnormally within a few ten of milliseconds.
