多选题Which two multicast protocol statements are true？ （Choose two.） （）ADense mode multicast requires explicit join messages from their members.BDense mode multicast uses a push model to flood traffic throughout the network and then prunes the unwanted traffic.CSparse mode multicast uses a pull model to send multicast traffic to where it is requested.DSparse mode uses reverse path forwarding （RPF） to prune off redundant flows.EThe primary use of sparse mode multicast is for test labs and router performance testing.
