Which is a characteristic of PIM sparse mode?
- It uses a pruning mechanism to stop the flow of unwanted multicast traffic on interfaces with no downstream neighbors.
- It requires an RP on the network to act as the root of the shared distribution tree.
- It builds the multicast tree by flooding traffic out all interfaces.
- It is designed for networks where receivers are located on every subnet in the network.
Explanation: PIM sparse mode chooses one or more routers to operate as rendezvous points (RPs). An RP is a single common root placed at a chosen point of a shared distribution tree.
