    About this ebook

    Welcome to Red Hat Certification World!

    This is mostly the first step you take into the world of Red Hat Certifications. Wonderful step when you start it with Red Hat RHCSA 9 (EX200) Capsules book which will help you prepare and practice for the exam.

    We will walk together through the exam objectives; which is publicly available in the EX200 Exam Objectives Section in Red Hat official site; that are required before going to the actual exam. Practicing a lot is a key point here, so, please, practice, practice, practice!

    We will review examples for each objective point from EX200 exam objectives that will let you get ready for the actual exam.

    To make it clear! This is not the actual exam of-course as this is violating Red Hat exam NDA "Non Disclosure Agreement"! This is for Educational purposes only to get you ready for the exam and get your hands dirty with more practices and examples!

    Also, I will never ever explain each and every word I'm talking about here! I follow the capsules concept. If you need something else, you will find many; and I mean it; many resources out-there which cover the theoretical and other stuff in more details. Are we clear?!

    By the way, you can manipulate and customize any files or any configurations mentioned in the book as much as you want for the purpose of practicing things very well, why not! Just please revert it back or keep what we've mentioned in the capsules there; if it does not conflict with any other things you would put/change; when done with practicing so we can follow up and continue with our capsules!

    What will be included in the book to be able to master RHCSA (EX200) Exam:
    * Understand and use essential tools such as commands with correct syntax, input-output redirection, grep, creating links, setting permissions ...etc
    * Scripting is the beauty of Red Hat world! We will go through creating shell scripts in a simple way!
    * Operate running systems is the day-to-day activity! We will manage many examples here!
    * Configuring local storage and filesystems is an important activity which will be covered in a simple way in upcoming capsules!
    * Maintaining systems is a core activity we do in the Red Hat world! Let's make it easy ;) !
    * Networking!!!
    * Manage users and groups!
    * Security is important! Let's learn how to secure our environment!
    * Containers is a wonderful world! Let's fly through it!
    * LAB preparation steps that we will use during practicing the provided examples.
    * Exam tips and tricks ;) !
    and many more...

    Again; all this will be in a short, simple, and easy to implement "Capsules" that will allow you to understand easily and quickly with simplicity what is needed and how to implement it even in real life! Capsules are short and direct to the point so let's keep it like that!

    This is also important and let us make it clear:
    I'm assuming that you are already familiar with RHCSA topics and/or having enough experience with Red Hat System Administration tasks. I assume also that you have attended Red Hat System Administration I (RH124) and Red Hat System Administration II (RH134) or RHCSA Rapid Track course (RH199) or having equivalent experience. I will explain in-short what I'm doing to keep the capsule simple and easy! But, please make sure you are really familiar with RHCSA topics in order not to be unsatisfied with the capsules! As mentioned before, there are lots of resources and books out-there for learning such things. Here you will get ready for the exam through Capsules! Are you ready ?!

    NOTE:
    I might use references or links from older Red Hat versions "why not! `ls` command still `ls` since it was created!"; as far as those references still valid to what we are discussing!

    One favor is required from you: Your feedback matters to me, so, please let me know your feedback and your review about this eBook.
