The EX200 Red Hat Certified System Administrator (RHCSA) exam tests whether you can administer a Linux system by doing the work. The best study method is to build a virtual machine and practice tasks until the commands come without notes.
Books and videos help. Typing commands and fixing your own mistakes helps more.
What the RHCSA proves and who it fits
The RHCSA is Red Hat's entry-level system administrator certification. You can read the official exam page at redhat.com. Red Hat lists the exam under its training and certification offerings, next to the Red Hat System Administration I course.
It fits you if you:
- Work as a junior sysadmin or help desk technician moving toward servers.
- Run Red Hat Enterprise Linux or a compatible distribution at work.
- Want a skills-based credential instead of a multiple-choice one.
Check the official page before you book. It holds the current objective list, the exam version and the format details. Those can change, and Red Hat is the only authority on them.
The skills to practice, grouped into task areas
The exact objective list and its wording are on the official EX200 page. Read it first and compare it with your practice list.
Use the grouping below as a practice checklist. It is our own organization, not Red Hat's weighting.
| Task area | What to be able to do without notes |
|---|---|
| Shell and files | Use grep, find, tar, redirection, vim, file permissions, ACLs |
| Software | Configure repositories, install and remove packages with dnf |
| Users and groups | Create users, set passwords and aging, manage sudo access |
| Storage | Partition disks, build LVM volumes, mount filesystems through /etc/fstab |
| Services and boot | Use systemctl, set the default target, recover a system that will not boot |
| Networking and firewall | Set IPs with nmcli, set hostnames, use firewall-cmd |
| Security | Manage SELinux modes and file contexts, check logs |
| Scheduling and processes | Write cron jobs, tune priorities, kill processes |
Two worked drills: persistent LVM storage and a web server
Storage tasks are where many candidates lose time. Practice this one until you can do it from memory. It assumes a spare disk at /dev/vdb.
sudo pvcreate /dev/vdb sudo vgcreate vgdata /dev/vdb sudo lvcreate -n lvapp -L 500M vgdata sudo mkfs.xfs /dev/vgdata/lvapp sudo mkdir /srv/app echo '/dev/vgdata/lvapp /srv/app xfs defaults 0 0' | sudo tee -a /etc/fstab sudo systemctl daemon-reload sudo mount -a df -h /srv/app Then reboot and run df -h /srv/app again. If the mount is gone, your /etc/fstab line is wrong.
The second drill combines SELinux, the firewall and a service. You will serve web content from a custom folder. Start with the setup:
sudo dnf install -y httpd sudo mkdir -p /srv/web Next, edit /etc/httpd/conf/httpd.conf. Point DocumentRoot to "/srv/web". Change the matching <Directory> block to "/srv/web" too. Without this, httpd will not serve the folder.
Then set the SELinux context, open the firewall and start the service:
sudo semanage fcontext -a -t httpd_sys_content_t '/srv/web(/.*)?' sudo restorecon -Rv /srv/web sudo firewall-cmd --permanent --add-service=http sudo firewall-cmd --reload sudo systemctl enable --now httpd Check the result with ls -Z /srv/web and firewall-cmd --list-all. Put a test file in /srv/web and fetch it with curl http://localhost/.
An 8-week study plan with weekly hours
This plan assumes you know basic Linux commands and can give 8 to 10 hours a week. That is about 76 hours in total. Add weeks if you are new to Linux. Cut a week or two if you already administer RHEL daily.
| Week | Hours | Focus | Practice goal |
|---|---|---|---|
| 1 | 8 | Lab setup, shell, files, permissions | Build a RHEL VM with a second disk and a snapshot |
| 2 | 8 | Text tools, archives, vim, ACLs | Do 10 file tasks with no notes |
| 3 | 10 | Users, groups, sudo, software repos | Add a local repo and install from it |
| 4 | 10 | Partitions, LVM, /etc/fstab | Repeat the LVM drill 3 times |
| 5 | 10 | systemctl, boot targets, boot recovery | Break the boot on purpose, then fix it |
| 6 | 10 | Networking, firewall, SELinux | Complete the web server drill from memory |
| 7 | 10 | Cron, processes, logs, tuning | Run mixed tasks against a clock |
| 8 | 10 | Full timed practice sessions | Do two full mock runs, then fix every miss |
Keep a log of every task that took you too long. Redo those first in the next session.
A simple readiness checklist
You are close when you can do all of these:
- Rebuild your VM and finish a mixed task list without searching the web.
- Pass your own reboot test, so every change survives a restart.
- Use
manpages and/usr/share/docto find an option you forgot. - Finish a timed practice session with time left to verify your work.
Common mistakes that cost points
Most failures in hands-on exams come from habits, not missing knowledge. These patterns are common:
- Skipping the reboot test. A change that does not survive a restart often counts as not done.
- Turning SELinux off. Fix the context with
restoreconinstead. Disabling it is a bad habit and may fail the task. - Forgetting
--permanenton firewall rules. The rule disappears after a reload or reboot. - Editing
/etc/fstabwithout testing. Always runmount -abefore you reboot. - Memorizing instead of practicing. Reading a command does not build the speed you need.
- Relying on practice dumps. They teach answers, not skills, and the exam rewards skills.
If you have no spare hardware, a free tier helps. Red Hat's navigation lists a no-cost Red Hat Learning Subscription trial and hands-on labs. Check the terms on redhat.com.
Voucher price, validity and refund terms

The full terms are on our refund policy and delivery policy pages.
What to do after you pass
Use the momentum while the commands are fresh. Red Hat's training menu lists the Red Hat Certified Engineer exam and the Red Hat Certified OpenShift Administrator exam as next steps. Both build on system administration skills.
You can also browse our Linux and server administration certifications to compare other paths.
When you are ready to book, you can get the EX200 RHCSA voucher for $338.99.
