In PIM-SM what control plane signaling must a multicast source perform before it begins to send multicasttraffic to a group?()

  • A、The source must send a PIM Register message to the rendezvous point (RP).
  • B、The source must first join the multicast group using IGMP before sending.
  • C、The source must perform a Request to Send (RTS) and Clear to Send (CTS) handshake with the  PIM designated router (DR).
  • D、No control plane signaling needs to be performed; the source can simply begin sending on the local  subnet.
