QUESTION 101
What is the difference between a source tree and a shared tree in a multicast environment?

To route traffic from source to receiver a source tree uses a link-state routing protocol and a shared tree uses a distance-vector routing protocol.

To stream multicast from source to receiver, a source tree uses PIM-SM and a shared tree uses PIM-DM.

Source trees are the default type for bidirectional PIM, and PIM-DM uses shared trees by default.
