Red Hat RHCSA EX200: Complete Preparation Guide
RHCSA is the entry-level Red Hat certification, entirely hands-on. 3 hours, real RHEL 9 systems, no multiple choice. Full task categories, the 20 commands that make or break your exam, and a 6-week plan.
RHCSA (Red Hat Certified System Administrator, exam code EX200) is what separates people who claim Linux experience from people who have it. Three hours, a live RHEL 9 system, and 20+ tasks to complete without documentation. This guide covers everything on the current EX200v9 objective list, the commands that repeat every exam, and a 6-week practical prep plan.
§RHEL 8 vs RHEL 9 (EX200v9)
The current exam is on RHEL 9. Key changes vs the RHEL 8 version: system-wide crypto policies via update-crypto-policies, nftables replaces iptables in most reference docs, and podman fully replaces docker. Skip any older study material that references RHEL 7 or systemd-networkd.
§Exam format at a glance
- 3 hours
- Performance-based on a live RHEL 9 system
- No internet, no notes
- Pass mark: 210/300 (70%)
- USD 500 (kiosk) or included in Red Hat training bundles
- Valid 3 years
- Retake: USD 275 within 30 days
§Exam domain weighting
| Domain | Weight | Focus |
|---|---|---|
| Essential tools | 10% | grep, sed, awk, find, redirections |
| Operate running systems | 15% | systemctl, journalctl, boot targets |
| Configure local storage | 15% | fdisk, LVM, XFS, swap |
| Create and configure filesystems | 15% | mount, /etc/fstab, ACLs, autofs |
| Deploy, configure, maintain systems | 15% | dnf, systemd, cron, ssh, tuned |
| Manage users and groups | 10% | useradd, passwd aging, sudoers |
| Manage security | 10% | firewalld, SELinux, SSH keys |
| Manage containers | 10% | podman, quadlet, rootless containers |
§Concepts that repeat on the exam
- systemctl daemon-reload after any /etc/systemd/system change - always
- LVM extend requires: pvresize → lvextend → xfs_growfs
- SELinux troubleshooting: sealert, ausearch -m avc, restorecon
- firewalld: always use --permanent + --reload; runtime-only changes get lost
- podman generate systemd (or quadlet in RHEL 9) for boot-persistent containers
- find + -exec runs a command per file; xargs is faster for bulk
§The study plan
- Weeks 1–2: Install RHEL 9 (or free Rocky/Alma), work through Sander van Vugt's video course
- Weeks 3–4: One task category per day - do every objective from memory, then re-do without notes
- Week 5: Timed 3-hour simulations (Sander van Vugt has 3; do all)
- Week 6: Only weak areas. If SELinux breaks you, spend the whole week on it
§Answer patterns and exam-day tips
- Reboot the system after every major change and confirm it survives - persistence is graded
- Read all questions before starting - some depend on others
- Use man pages heavily (allowed in exam) - man -k or /keyword saves time
- tuned-adm active shows current profile - small mark, easy to miss
- Never leave the boot loader password change until last - it needs a reboot
"RHCSA is the Linux cert that separates people who can talk about Linux from people who can operate it. If you can't fix a broken SELinux context in under 3 minutes, keep practicing."
§Salary reality - Bangladesh, UAE, KSA and remote
| Role | Location | Salary band |
|---|---|---|
| Linux sysadmin | Dhaka | BDT 60k–140k/month |
| System engineer | Dubai | AED 12k–22k/month |
| Infrastructure admin | Riyadh | SAR 11k–20k/month |
| RHEL contractor | Remote | USD 50–90/hr |
§Best resources
- Sander van Vugt RHCSA video course (the definitive prep)
- Red Hat Learning Subscription (if employer pays)
- 'RHCSA Red Hat Enterprise Linux 9' by Asghar Ghori
- Free Rocky Linux 9 or Alma Linux 9 for hands-on labs
- man pages - the only 'notes' allowed in the exam
