Selected Answer: C

The symptoms, including high CPU usage and rapidly blinking switch lights, are most likely due to a cable loop in the network causing a broadcast storm, which is overwhelming network resources and disrupting connectivity.

Selected Answer: C

C. A cable was looped and created a broadcast storm. The symptoms described, including high CPU usage on the switch, rapidly blinking lights, and users being unable to access network resources, are indicative of a broadcast storm. A broadcast storm occurs when there is a loop in the network, causing broadcast traffic to circulate endlessly and overwhelm the network.
