CCDE: Cisco Certified Design Expert (Practical) — Question 154

Company XYZ network runs IPv4 and IPv6 and they want to introduce a multidomain, multicast-based network. The new design should use a flavor of PIM that forwards traffic using SPT. Which technology meets this requirement?

Answer options

Correct answer: B

Explanation

PIM-SM (Protocol Independent Multicast - Sparse Mode) is designed for scenarios where multicast groups are sparsely populated, making it suitable for forwarding traffic using SPT. PIM-SSM (Source-Specific Multicast) is limited to specific sources and does not provide the same flexibility as PIM-SM. BIDIR-PIM is used for bidirectional communication, which is not required here, and PIM-DM (Dense Mode) is less efficient for sparse group scenarios, making PIM-SM the best choice.
