Correct answer & explanation
GM initiates ISAKMP SA with KS
In GET VPN, a group member (GM) first registers with the key server (KS) using ISAKMP. The KS authenticates the GM and then pushes the current policy and encryption keys (TEK and KEK) to the GM. The KS periodically sends a rekey message to all GMs to update the keys before they expire.
