Designing Cisco Enterprise Networks (ENSLD) — Question 97

An engineer is designing a multicast network for a company specializing in VoD content. Receivers are across the Internet, and for performance reasons, the multicast framework must be close to the receivers within each AS. For high availability, if the sources in one AS are no longer available, the receivers of that AS must be able to receive the VoD content from the sources in another AS. Which feature must the design include?

Answer options

Correct answer: D

Explanation

The correct answer is D, MSDP, as it allows the sharing of multicast sources between different Autonomous Systems, enabling receivers to access content from alternative sources if their local sources fail. Option A, SSM, is not suitable for this scenario since it does not provide redundancy across AS boundaries. Option B, anycast RP, is not designed for high availability in inter-AS multicast. Option C, bidirectional PIM, is primarily for bidirectional traffic but does not specifically address the requirement for inter-AS redundancy.
