Building and repairing networks takes a small kit of specialized tools. The A+ exam often describes a task, such as finding which unlabeled cable goes to a wall jack or attaching a new plug to a patch cable, and asks which tool to use. Learn what each tool is for and the order you would use them in, and these questions become quick points.
