Designing Cisco Enterprise Networks (ENSLD) — Question 258

A network architect is enabling TV services in the LAN. The source will be streaming to the 239.1.1.1 group IP address. Dense mode is not allowed in the network. Multicast has already been enabled on all network devices in the LAN segment. Which action must the architect take to finalize the design?

Answer options

• A. Enable PIM SSM.
• B. Enable PIM Auto-RP.
• C. Enable PIM Anycast RP.
• D. Enable PIM BSR.

Correct answer: B

Explanation

The correct answer is B, as enabling PIM Auto-RP allows for automatic discovery of multicast sources and receivers, which is essential in a sparse mode environment where dense mode is not permitted. The other options, such as PIM SSM, Anycast RP, and BSR, do not address the need for automatic RP discovery in this specific scenario.
