After several inspectors leave the permit-counter BSS, the WLAN still needs to refresh keys used for broadcast/multicast frames to remaining stations. Which handshake concept addresses that group-key renewal?
Select an answer to reveal the explanation.
Short Explanation
When someone leaves the party, you don’t always re-key every private whisper—but you do change the shared punch-bowl password. That’s the group key handshake refreshing the GTK for broadcasts still hitting the room.
Full Explanation
Group key handshakes update the GTK used to protect group-addressed frames as membership and policy require. That is distinct from mechanisms that only refresh pairwise keys. DHCP FORCERENEW is not the 802.11 GTK renewal method, and simply disabling broadcast is not the standard AKM answer for group-key management.
