One solved question, so you can see how these are marked

What does storm control on a switch port do?

It limits broadcast, multicast or unicast traffic that exceeds a configured threshold on the port

Storm control measures traffic of a selected type over an interval, and when it exceeds the threshold it suppresses it or takes another configured action. This protects the switch and hosts from a broadcast storm.
