Throughout the book, figures, tables, screen shots, examples, and exam tips have been furnished to support explanation and exam preparation. This book includes four sample exams for RHCSA, which are expected to be done using the knowledge and skills attained from reading the material and practicing the exercises and challenge labs. The labs and the sample exams include references to relevant topics and/or exercises. From the Author Red Hat ® had revised their EX200 exam for the RHCSA certification soon after the release of Red Hat ® Enterprise Linux ® version 8 in April 2019. As usual, these exams are performance-based and present scenarios that are to be accomplished on live systems within a stipulated time. This book is written to provide necessary coverage of theoretical and practical information to help you pass the exam. Furthermore, this book may be used for classroom trainings and as a deskside reference. Keeping in mind the hands-on nature of the exam, I have included a multitude of step-by-step exercises and Do-It-Yourself (DIY) challenge labs throughout the book. Chapter 01 details the infrastructure that is needed to practice the procedures and perform the labs. It also outlines how to obtain a copy of RHEL 8.

I have provided several review questions with answers at the end of each chapter. Take the quiz and then attempt the DIY challenge labs offered thereafter. I have not furnished solutions to these labs intentionally, as I am confident that the knowledge and skills you will have gained by that time will be sufficient to accomplish the labs on your own; and, in essence, this is what I want you to eventually get at. Once you have read and understood the material, performed exercises, completed review questions, and accomplished DIY challenge labs, take time to attempt the sample RHCSA exams provided in appendices. While performing exercises and labs, if a command does not produce the published result, I advise that you check the message the command has generated and consult relevant logfiles. Minor issues, such as a wrong path or typo, prevent commands from executing correctly. Sometimes, syntax errors in command constructs could result inexecution failures. You might have to make modifications to your command in order to run it as expected. RHEL manual pages prove helpful in comprehending commands and their
