HW is using Sparse Mode PIM within its IP multicast network.
In PIM-SM, what control plane signaling must a multicast source perform before it begins to send multicast traffic to a group?
A . The source must perform a "Request to send" (RTS) and "Clear to send" (CTS) handshake with the PIM Designated Router (DR) on the local subnet.
B . The source sends a PIM register message to the Rendezvous Point (RP).
C . The source must first join the multicast group using IGMP before sending.
D . No control plane signaling is required. The source just begins to send on the local subnet.
Answer: D
