What is a key difference between PIM-SM and PIM-SSM regarding multicast state?

PIM-SM supports only one source per group, while PIM-SSM supports many

PIM-SM requires IGMPv3, while PIM-SSM works with IGMPv2

PIM-SM maintains only (S,G) state, while PIM-SSM maintains (*,G) state

PIM-SM uses both (*,G) and (S,G) state, while PIM-SSM uses only (S,G) state

In PIM Sparse Mode, what is the primary role of the rendezvous point (RP)?

To forward all multicast traffic directly from sources to receivers using the shortest path

To perform RPF checks on all multicast packets entering the PIM domain

To elect the designated router for each multi-access segment in the network

To act as the meeting point where receivers join and sources register to build the shared tree

In PIM-SM, what triggers the switchover from the shared tree to the shortest path tree?

The RP sends a prune message to the source after the first packet is received

The last-hop router receives the first multicast packet via the shared tree and initiates an (S,G) join

The source sends a register-stop message to the RP after the shared tree is fully built

The designated router on the source's segment floods a join message to all PIM neighbors

What is the role of Multicast Listener Discovery (MLD) in IPv6 networks?

To discover IPv6 routers on the local segment

To resolve IPv6 addresses to MAC addresses

To allow hosts to signal IPv6 multicast group membership to routers

To assign IPv6 addresses to hosts automatically

A service provider is designing multicast for a large-scale financial trading application where many sources send to the same group and many receivers join the group. The traffic pattern is many-to-many, and the provider wants to minimize the amount of multicast state in the core. Which PIM mode should be used?
