Course 5: Troubleshoot with Time
As the Golden Rule of Networking states, you should get what you ask for in a timely manner. In this course, Laura focuses on the various methods for measuring path, client/server, and application time delays. You will also learn when there are delays that are considered “normal” and not a problem – don’t get stuck wasting time troubleshooting these delays! Throughout this course, you will add buttons to your Troubleshooting Online Class profile so you can quickly detect delays in the future.
