Designing Cisco Enterprise Networks (ENSLD) — Question 118

A network engineer must design a multicast solution to prevent the spoofing of multicast streams and ensure efficient bandwidth utilization. The network will be merged with another multicast domain in the future, and the merge must require minimum effort. Which two solutions meet the customer requirements? (Choose two.)

Answer options

Correct answer: A, B

Explanation

PIM-SSM (A) is designed for secure and efficient multicast stream management, while IGMPv3 (B) supports source-specific multicast, which enhances security against spoofing. In contrast, IGMPv2 (C) does not provide the same level of security, and PIM-SM (D) and MSDP (E) are not as effective for the specific requirements outlined, particularly in relation to the ease of merging with another multicast domain.
