Acompany streams video tomultiple devices across a campus.When this happens,several users
report adegradationofnetworkperformance.WhichofthefollowingwouldMOSTlikelyaddress
thisissue?
A. Enable IGMP snooping on the switches.
B. Implement another DHCP server.
C. Reconfigure port tagging for the videotraffic.
D. Change the SSID of the APs

Enable IGMP snooping on the switches

IGMP snooping helps manage multicast traffic, which is typically used for streaming video. By enabling IGMP snooping on the switches, they can listen to IGMP messages and maintain a list of which devices are part of which multicast groups. This way, the switches can forward multicast traffic only to the ports where the interested receivers are located, reducing unnecessary traffic on other ports and improving overall network performance.
