Which two statements about Protocol Independent Multicast (PIM) are true? (Choose two.)
- PIM does not require an IGP protocol to be configured in the network.
- PIM should be configured only on the first and the last hop routers in the multicast tree.
- PIM should be configured on the device that hosts the source of the muticast traffic.
- PIM sparse mode is most useful when there are few senders, many receivers, and the volume of multicast traffic is high.
- PIM is a multicast routing protocol that makes packet-forwarding decisions independent of the unicast IP routing protocol that is running in the network.
- Three of the forwarding modes for PIM are PIM dense mode (PIM-DM), PIM sparse mode (PIM-SM), and PIM sparse-dense mode.
Answers Explanation & Hints:
PIM is a multicast routing protocol that routes multicast traffic between network segments by creating distribution trees. It makes packet-forwarding decisions independent of the unicast IP routing protocol that is running in the network. There are five operating PIM modes:
PIM dense mode (PIM-DM)
PIM sparse mode (PIM-SM)
PIM sparse dense Mode
PIM source specific multicast (PIM-SSM)
PIM bidirectional mode (Bidir-PIM)
