An engineer is troubleshooting slow performance issues on a customer’s network after the last multicast configuration change was applied on it. While checking the running configuration on the router, the engineer notices there are many ip igmp join-group commands applied on several interfaces of the router which caused the high CPU utilization usage. What action must the engineer take to solve this issue?
A. Configure all router interfaces to be process-switched by increasing the query interval
B. Remove ip igmp join-group command on all unnecessary interfaces
C. Remove unnecessary members from the IGMP group
D. Configure ip igmp static-group command on all interfaces
To be honest this question is not totally clear. In the assumption that the igmp join-groups are removed D. would be the correct answer, since the igmp static-group forwards the multicast group out of the interface on which it is configured, but is does not process it. But in this case B is the correct answer
