RHCSA EX200 on RHEL 10: Exam Objectives, Lab Practice and a Study Plan

Key takeaways

• EX200 is performance-based: you configure real systems, not answer multiple-choice questions.
• Practise on RHEL 10 or a compatible rebuild such as Rocky Linux or AlmaLinux; CentOS Linux is end-of-life.
• Storage, SELinux, firewalld, users and containers are the areas to drill daily.
• Use only the official objectives as your checklist; check for changes before booking.
• Build a repeatable lab so you can reset and redo tasks quickly.

What is RHCSA EX200?

RHCSA stands for Red Hat Certified System Administrator. Its exam code is EX200, and it is now based on Red Hat Enterprise Linux 10. The exam is practical: you receive tasks on live systems and must complete them correctly, usually with no internet access beyond the documentation available on the system. RHCE is the next step and uses exam EX294, which focuses on Ansible automation. Red Hat sets the exam duration, price and exact objectives, so confirm them on the official Red Hat training and certification pages before booking.

What do the objectives cover?

Treat this table as a study map only. The official exam objectives are the final authority, and they can change.

How should you set up a lab?

1. Create two or three RHEL 10 virtual machines (or Rocky Linux or AlmaLinux) in VirtualBox, VMware or KVM. Red Hat offers a no-cost developer subscription for individual use; check the terms on the Red Hat site.
2. Add extra virtual disks to practise partitions and LVM.
3. Take a snapshot of a clean install so you can reset in seconds.
4. Practise from the command line, using only man pages and /usr/share/doc for help, as in the exam.

What is a good study order?

1. Essential tools, permissions and users, until they are automatic.
2. Services, processes, boot targets and logs.
3. Storage and LVM, including persistent mounts using UUIDs. Test with a reboot.
4. Networking and firewalld.
5. SELinux: labelling, contexts, booleans and troubleshooting denials.
6. Software management and scheduled jobs.
7. Containers with Podman, including persistent storage and systemd services.
8. Full timed practice exams made from the objectives.

Which tasks trip people up?

• Configuration that works until reboot because it was not made persistent.
• SELinux denials after changing a web content directory.
• Typos in /etc/fstab that stop the system booting.
• Forgetting to open a firewall port permanently, or to reload.
• Running out of time because of slow typing of long commands. Build shell fluency.

What is a practice example?

Task: create a 500 MiB logical volume named data in volume group vg0, format it with XFS, mount it at /data persistently and verify after reboot. Commands to know: lvcreate -L 500M -n data vg0, mkfs.xfs /dev/vg0/data, an /etc/fstab entry, mount -a and findmnt. Do it again from scratch without notes until it takes only a few minutes.

Common mistakes

• Studying RHEL 8 or 9 material for an exam based on RHEL 10.
• Reading about tasks instead of performing them.
• Not rebooting to verify persistence.
• Disabling SELinux instead of fixing it.
