This chapter is designed to help you learn more about the concepts, best practices, and commands tested by the LPI 201 Exam. It is organized according to the LPI Objective Topics (e.g., Networking Configuration, DNS, Network Client Management). Even advanced Linux users will find these activities useful, because they are all based on the LPI's Objectives. The things you read about in this chapter might help remind you how to do tasks that you may not have had to do in a while.

It is best if you use a live, nonproduction Linux system to conduct these exercises. This way, you can apply your knowledge, but still not worry too much if your experiments cause the system to become unstable or to no longer be as secure as before.
