What is the purpose of the PIM Register mechanism?

To discover neighboring PIM routers.

To allow the first-hop router to send multicast traffic to the RP for delivery down the shared tree.

To quickly rejoin a pruned branch.

To elect the designated router on a multi-access segment.

What is the primary purpose of PIM hello messages?

To announce the RP for multicast groups.

To request multicast traffic for a group.

To discover and maintain neighboring PIM routers.

To resolve duplicate forwarding on a multi-access network.

What is a primary disadvantage of PIM Dense Mode in a network with sparse receiver distribution?

It periodically floods traffic even to branches without receivers, wasting bandwidth.

It cannot support more than 256 multicast groups.

It requires a configured Rendezvous Point for every group.

It requires all routers to be configured with the same static RP.

What is a key advantage of PIM Sparse-Dense Mode over running separate sparse and dense mode configurations?

It reduces the number of hello messages sent on the network.

It allows a single interface to support both sparse and dense groups automatically.

It provides better security by encrypting multicast traffic.

It eliminates the need for RPs entirely.

What is the primary role of the Bootstrap Router (BSR) in PIM Sparse Mode?

To elect the designated router on each multi-access segment.

To distribute RP information to all PIM routers in the domain.

To maintain the multicast forwarding table for all groups.

To forward multicast traffic between different PIM domains.

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 26 practice questions to prepare you well beyond it.
