350-501 Question #506: Real Exam Question with Answer & Explanation
The correct answer is C: Enable PIM-SSM across the network.. PIM-SSM (Protocol Independent Multicast - Source-Specific Multicast) provides the most efficient path for multicast data flow by eliminating the need for shared trees and Rendezvous Points (RPs). It allows receivers to explicitly request traffic from a specific source, such as th
Question
A network engineer must enable multicast on the network to support a new series of webcasts. The PIM protocol has been enabled on the LAN side, with PIM and MSDP capabilities on edge router R1. The multicast source has been configured with IP address FF3A::121, and IP protocol 58 has been enabled and successfully tested in the network. Due to the limitations of some devices on the network, the data flow should take the most efficient path. Which task must the engineer perform to achieve the goal?
Options
- AEnable PMI BSR on R1.
- BImplement Anycast RP on R1.
- CEnable PIM-SSM across the network.
- DImplement PIM-SM in the LAN.
Explanation
PIM-SSM (Protocol Independent Multicast - Source-Specific Multicast) provides the most efficient path for multicast data flow by eliminating the need for shared trees and Rendezvous Points (RPs). It allows receivers to explicitly request traffic from a specific source, such as the multicast source at IP address FF3A::121, using IGMPv3 or MLDv2. This ensures minimal overhead and the most direct routing for multicast traffic, meeting the requirement for efficient data flow while accommodating device limitations in the network.
