Configuration changes made on a physical port that is a member of a port-channel interface apply to the port-channel interface. C . Configuration changes are not permitted with Port Aggregation Protocol； instead， the standardized Link Aggregation Control Protocol should be used if configuration changes are required. D .

A .  Dense mode multicast requires explicit join messages from their members. B .  Dense mode multicast uses a push model to flood traffic throughout the network and then prunes the  unwanted traffic. C .  Sparse mode multicast uses a pull model to send multicast traffic to where it is requested.   D .  Sparse mode uses reverse path forwarding （RPF） to prune off redundant flows. E .  The primary use of sparse mode multicast is for test labs and router performance testing.
