A multicast router receives a packet on interface ge-0/0/0. The unicast route to the source address points to ge-0/0/1. What is the purpose of the RPF check in this scenario?

To verify the group address is valid

To determine the outgoing interface list for the group

To ensure the packet arrived on the interface closest to the source

To prevent the packet from being forwarded to the source

Which multicast model allows receivers to receive traffic from any source that sends to the group, and typically uses a shared tree rooted at a Rendezvous Point (RP)?

Source-Specific Multicast (SSM)

What is a key characteristic of Source-Specific Multicast (SSM) compared to Any-Source Multicast (ASM)?

SSM uses the 239.0.0.0/8 address range.

SSM requires receivers to specify both the source and the group address.

SSM uses a Rendezvous Point (RP) to build the distribution tree.

SSM allows any source to send to the group.

Part of the IP Multicast domain, which makes up ~8% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~3–5 in this domain), expect 1–2 from this objective — we provide 24 practice questions to prepare you well beyond it.
