Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 130

A network operator needs to implement PIM-SSM multicast configuration on a customer's network so that users in different domains are able to access and stream live traffic. Which two actions must the engineer perform on the network to make the streaming work? (Choose two.)

Answer options

• A. Enable IGMP version 3 at the interface level.
• B. Enable PIM dense mode on the device.
• C. Enable PIM sparse mode on the device.
• D. Enable IGMP version 2 at the interface level.
• E. Configure at least one MSDP peer on the network.

Correct answer: A, C

Explanation

The correct answers are A and C because IGMP version 3 is required for PIM-SSM to allow for source-specific multicast, and PIM sparse mode is necessary for efficient multicast traffic management in this scenario. Options B and D are incorrect as PIM dense mode is not suitable for SSM, and IGMP version 2 does not support the needed multicast features.
