Refer to the exhibit.
A university runs its own TV station in the city. The IT department deploys a multimedia server so the TV productions can be sent out to the entire campus over the IP network using multicast-based communications. In order to improve the bandwidth consumption, PIM Sparse Mode and IGMP Snooping features are enabled.
When wireless users join the multicast groups, all users connected to the same WLAN experience poor network performance. However, wired users are not affected in this way. While troubleshooting, the network administrator saves the packet captures shown in the exhibit and concludes that all users, even those not joining the multicast group, receive the same multicast flow at slow speeds.
Which features should the network administrator enable to fix the problem?
