Which statement is true about Protocol Independent Multicast Dense Mode (PIM multicast routing?
A. PIM DM supports shared distribution trees.
B. If a port is pruned, the administrator must re-enable the port to support multicast traffic.
C. The (S,G) state exists in every router, regardless of the presence of an RPF interface.
D. Flooding of traffic only occurs in the beginning stages of routing. Afterwards, all necessary ports are pruned and multicast traffic is not sent across those interfaces.
