Which Junos configuration statement is used to enable PIM on an interface?

set protocols pim interface ge-0/0/0

set protocols pim rp interface ge-0/0/0

set protocols igmp interface ge-0/0/0

set routing-options multicast interface ge-0/0/0

A multicast stream from source 192.168.1.10 to group 239.2.2.2 is not reaching receivers. The administrator checks the multicast route table and sees an entry for the group, but the incoming interface is listed as 'None'. What does this indicate, and what should the administrator check next?

The group membership is missing; check IGMP on the receiver-facing interface.

PIM is not enabled on the incoming interface; check the PIM configuration on all interfaces.

The router has no route to the source; check the unicast routing table for a path to 192.168.1.10.

The RP is unreachable; check the PIM neighbor adjacency with the RP.

A campus network has a multicast video service that must reach all local users. The network team wants to prevent this multicast traffic from leaking out to the regional WAN, while still allowing other multicast traffic to cross the WAN. The WAN interface is ge-0/0/0. Which configuration should be applied?

Apply an administrative boundary for the video group range on ge-0/0/0.

Configure a multicast scope zone for the video group on the campus routers.

Set a TTL threshold of 1 on ge-0/0/0.

A company uses multicast for internal software distribution across its WAN. The network team wants to ensure that multicast traffic from a specific source subnet (10.10.0.0/16) is not forwarded beyond the local site, while allowing multicast from other sources to traverse the WAN. Which configuration should be applied on the WAN router?

Set a TTL threshold of 2 on the WAN interface.

Apply a routing policy that rejects multicast routes with a source prefix of 10.10.0.0/16 on the WAN interface.

Disable PIM on the WAN interface.

Configure an administrative boundary for the group range used by the source.

When applying a routing policy to control multicast route advertisement, which Junos configuration statement is used to apply the policy to multicast routes?

set protocols pim export POLICY

set routing-options multicast export POLICY

set policy-options policy-statement POLICY term 1 from protocol pim

set protocols igmp export POLICY

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 21 practice questions to prepare you well beyond it.
