Designing Cisco Enterprise Networks (ENSLD) — Question 93

An architect is designing a multicast solution for a network that contains over 100 routers. The architect plans to create several multicast domains and balance the
PIM-SM traffic within the network. Which technology should the architect include in the design?

Answer options

• A. DVMRP
• B. IGMP
• C. MOSPF
• D. MSDP

Correct answer: D

Explanation

The correct answer is D, MSDP, as it allows for the sharing of multicast group information between different PIM-SM domains, facilitating the interconnection of multicast sources across multiple domains. The other options, such as DVMRP and MOSPF, are not suitable for this scenario as they focus on specific routing protocols rather than the inter-domain multicast sharing that MSDP provides.
