How can ASM and SSM coexist in a single multicast network?

By using different multicast address ranges for ASM and SSM groups

By disabling PIM on the routers that support SSM

By configuring separate Rendezvous Points for each model

By using different IGMP versions on the same interface

Which of the following is a key difference between ASM and SSM in terms of tree types?

ASM uses only shortest-path trees, while SSM uses shared trees

Both ASM and SSM use the same tree types

ASM uses shared trees initially, while SSM uses only shortest-path trees

ASM uses only shared trees, while SSM uses only shortest-path trees

A network administrator is deploying multicast for a corporate event where multiple sources may transmit to the same group. The sources are not known in advance. The administrator wants to use ASM with PIM-SM. What is required for this deployment to function?

A shortest-path tree built directly from each source

IGMPv3 on all receivers and a static (S,G) join

A Rendezvous Point (RP) and shared-tree operation

PIM dense mode to flood traffic to all receivers

A service provider is troubleshooting a multicast issue. The network uses PIM-SM for ASM. Receivers are not receiving traffic from a new source. The source has registered with the RP, but the last-hop router is not forwarding traffic to the receivers. What is the most likely cause?

The last-hop router has not sent a join toward the RP for the group

The source is not sending traffic to the RP

The RP is not sending the traffic down the shared tree

A network engineer is configuring multicast for a live video feed where the source address is fixed and known to all receivers. The engineer wants to minimize state on the routers and avoid RP configuration. Which multicast approach should be used?

ASM with PIM-SM and a static RP

ASM vs. SSM JN0-664 Practice Questions (Page 3)

Part of the IP Multicast domain, which makes up ~18% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~6–11 in this domain), expect 1–1 from this objective — we provide 25 practice questions to prepare you well beyond it.
