A new assistant network administrator was recently hired by your organization to relieve some of your workload.

You assigned the assistant network administrator to replace a defective patch cable that connected port on your patch panel to one of your network switches. You noticed that it took him an unusually long time to complete this task. Once done, users almost immediately began to report that the network had gone down.

Upon entering the server room, you see that the assistant administrator has configured your network rack as shown below.
