This is a Red Hat Certified System Administrator (RHCSA) Study Guide.

About the RHCSA Exam:

• The RHCSA exam is hands on and performance-based (no multiple-choice questions).
• No actual exam material is contained within this guide.
• The RHCSA (EX200) Exam is 2.5 hours long.
• The minimum passing score is 210 out of 300 points (70%).
• The exam consists of about 10 to 15 questions.
• The exam objectives are here: https://www.redhat.com/en/services/training/ex200-red-hat-certified-system-administrator-rhcsa-exam
• More information on the exam can be found here: https://www.redhat.com/en/services/certification/rhcsa
• 10/13/2019 Update: I had to take a few months off due to work-related issues, but I do plan on continuing this project, as time allows.
  • RHEL 8 was recently released. There don't seem to be any changes to the objectives.
  • I recently moved from Syncthing to Dropbox because I needed a cloud backup of all my important files, so you will notice that I will slowly change links from /Sync to /Dropbox/sync0001. Please change them to whatever is appropriate on your system.

To build this study guide, I am using the following free software:

• Fedora (my GNU/Linux OS of choice): https://getfedora.org/
• Freemind (mind maps): http://freemind.sourceforge.net/wiki/index.php/Main_Page
• Zim Desktop Wiki: http://zim-wiki.org/
• Anki (flashcards): https://apps.ankiweb.net/
  • The Anki flashcard deck is shared here: https://ankiweb.net/shared/info/1832565974
  • See here for important information about how I share the flashcard deck on Anki: Anki Shared Deck
• git/git-gui (version control): https://git-scm.com/
• KVM (Kernel-based Virtual Machine that I use for hosting guest CentOS VM on Fedora): https://www.linux-kvm.org/page/Main_Page
• CentOS (Community Enterprise Operating System: guest OS for KVM): https://www.centos.org/

To get the most out of this study guide, I recommend the following:

• Have a standalone computer, or virtual machine, with the latest version of CentOS installed to do the exercises (https://www.centos.org/).
• Have a second computer, or a host PC, that meets the requirements below. You'll install the software listed below on this machine.
• If you decide to run CentOS in a guest VM:
  • I recommend having at least 2 monitors on the host PC. This makes simultaneously doing the examples and following the study guide easier.
  • I recommend using KVM as your virtualization software.
  • The host PC will need to have a fast CPU, and plenty of RAM (my original setup, an older quad-core AMD CPU with 4 GB of RAM, could not handle it at all).
  • The host PC's OS should allow:
    • running a guest CentOS VM.
    • installing Freemind, Zim, Anki, and git-gui.
    • I recommend Fedora: https://getfedora.org/
• On Fedora 30, you'd install the software with one of these 2 commands:
  • CASE A: sudo is not enabled for your account: su -c "dnf install freemind zim anki git-gui"
  • CASE B: sudo is enabled for your account: sudo dnf install freemind zim anki git-gui
• (optional) Sign up for a free AnkiWeb account (https://ankiweb.net/)
• Clone https://github.com/RexDjere/RHCSA to this directory on your Linux pc: /home/your_username/Sync/PROJECTS/RHCSA
• After cloning the git repository, RHCSA should have the following files/folders inside:
  • anki (holds exported text file containing all flashcard Q&As)
  • CODE_OF_CONDUCT.md
  • CONTRIBUTING.md
  • cpp_files (c++ files that I created)
  • examples (holds all study guide examples)
  • lectures - (contains lectures on a variety of GNU/Linux related topics)
  • LICENSE.md (contains GPL v3 license text)
  • lists (holds list text files that I use for examples)
  • MILESTONES.md
  • mindmaps (hold all mindmaps created with Freemind)
  • objectives (contains the RHCSA objectives)
  • PULL_REQUEST_TEMPLATE.md
  • README.md (the study guide's home page)
  • zim (holds all zim wiki pages)
  • .git (hidden file)
  • .github (hidden file)
• When you run Zim, you'll want to open the zim folder as a notebook. Once you do, you'll be able to navigate/edit all of the wiki pages.
• Freemind will allow you to open and edit the mindmaps, and Anki will allow you to view/edit the flashcards.
• git/git-gui will allow you to checkout the study guide, edit parts of it if you wish, and create pull requests to update the master branch.
• I'll periodically export the latest version of the Anki flashcards to the anki directory.

Enjoy the definitive RHCSA Study Guide!
