What is the key characteristic of anycast RP in PIM-SM?

Multiple RPs share the same IP address, and routers use the closest RP based on routing metrics

RPs are discovered dynamically using DHCP

Each RP has a unique IP address, and routers use a hash to select one

Only one RP is active at a time, and others are standby

A network has a mix of hosts: some support only IGMPv1, some support IGMPv2, and some support IGMPv3. The router is configured for IGMPv3. Which statement correctly describes how the router handles membership reports from these hosts?

The router processes IGMPv1 and IGMPv2 reports normally, but treats IGMPv3 reports as if they were IGMPv2 reports.

The router ignores reports from IGMPv1 and IGMPv2 hosts and only processes IGMPv3 reports.

The router processes IGMPv3 reports normally, but treats IGMPv1 and IGMPv2 reports as if they were IGMPv3 reports.

The router processes each report according to its own version, and the presence of IGMPv1 or IGMPv2 hosts may affect the querier version.

What is the primary purpose of IGMP snooping on a Layer 2 switch?

To reduce unnecessary multicast flooding by forwarding multicast traffic only to ports with interested receivers

To provide encryption for multicast traffic on the LAN

To translate IGMP messages between different IP versions

To replace the need for a multicast routing protocol like PIM

A multicast source begins sending traffic to a group in a PIM-SM network. Which statement correctly describes the registration process?

The source's DR sends a join message to the RP to join the shared tree.

The RP sends a join message to the source's DR to request the multicast traffic.

The source's designated router (DR) encapsulates the multicast packets and sends them to the RP in a register message.

The source's DR sends a prune message to the RP to stop the shared tree.

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.
