HPE Aruba Certified Network Security Expert (ACNSX) — Question 105

When comparing PIM-DM and PIM-SM, which multicast components are only found with PIM-SM in multicast routing? (Choose two.)

Answer options

• A. IGMP querier
• B. Rendezvous point
• C. Bootstrap router
• D. Shortest path tree
• E. Designated router

Correct answer: B, E

Explanation

The correct answers are B and E because the Rendezvous point is a critical component used in PIM-SM to facilitate multicast group management, while the Designated router plays a role in managing multicast traffic in PIM-SM networks. Options A, C, and D are not exclusive to PIM-SM; for instance, IGMP queriers and Bootstrap routers can be involved in both PIM-DM and PIM-SM, and Shortest path trees are utilized in both protocols as well.
