CCDE: Cisco Certified Design Expert (Practical) — Question 87
Company XYZ has a multicast domain that spans across multiple autonomous systems. The company wants to choose a technology that provides a simplified and controlled approach to interconnecting the multicast domains. Which technology is the best fit for this purpose?
Answer options
- A. PIM SSM
- B. MSDP
- C. PIM sparse mode
- D. MPLS
Correct answer: B
Explanation
The correct answer is B (MSDP) because it enables the interconnection of multicast domains across different autonomous systems by allowing them to share multicast group information. The other options, such as PIM SSM and PIM sparse mode, are primarily focused on local multicast routing rather than inter-domain communication, while MPLS is a general-purpose networking technology that does not specifically address multicast interconnection.
