Red Hat Certified System Administrator (RHCSA) #1: The Exam — EX200 format, environment, study strategy
If the 21-post RHEL operations track had you working hands-on with user management, storage, systemd, and SELinux, the next natural step is getting that feel validated with a certification. The starting point and the most fundamental hands-on exam in Red Hat’s Linux certification path is the Red Hat Certified System Administrator (RHCSA, exam code EX200). This series unpacks every domain you need to pass RHCSA across 16 posts.
RHCSA isn’t multiple-choice — it’s a hands-on exam where you carry out tasks on a real RHEL system. You have to create users, extend LVM, and fix SELinux contexts, all within a time limit. So this first post covers not only what the exam asks but also how to get through 2.5 hours with nothing but man pages and no internet.
What kind of certification is RHCSA #
RHCSA validates, hands-on, whether you can carry out a RHEL system administrator’s day-to-day work by hand. It’s not a test where you pick concepts — you sit in front of an empty shell and perform tasks like these directly.
- Create users and groups and grant privileges with sudo and ACLs
- Create and extend partitions and LVM, and add swap
- Create XFS and ext4 file systems and mount them permanently via fstab
- Control services with systemd and change the boot target
- Fix SELinux contexts and booleans so a service runs correctly
- Open ports with firewalld and run a container as a systemd service with Podman
Someone who passes this exam goes beyond using commands from memory — they can complete the tasks they encounter while operating RHEL on their own, referring to man pages.
Who gets value from it #
| Role | Why |
|---|---|
| System / infra engineers | Standard proof of enterprise Linux operations |
| Cloud / DevOps beginners | Securing an OS foundation before moving on to containers and automation |
| Backend developers | The vocabulary of server operations and a feel for troubleshooting |
| RHCE candidates | RHCE requires holding RHCSA to sit |
RHCSA is the foundation of Red Hat’s certification system, and it’s also a prerequisite for moving on to RHCE (Ansible automation). The tasks you learn here become the targets of “automate with Ansible” in RHCE, so we recommend firming up the manual work of RHCSA before moving on to RHCE.
Exam structure #
The surface-level facts about the RHCSA (EX200) exam are worth committing to memory.
| Item | Value |
|---|---|
| Format | Performance-based. You work on a real RHEL system |
| Exam time | 2.5 hours |
| Passing score | 210 / 300 (70%) |
| Validity | 3 years |
| Eligibility | None (anyone can sit) |
| Docs | No internet. Only local man pages and /usr/share/doc are allowed |
| Delivery | Test center or Red Hat Remote Exam (remote proctored) |
| RHEL version | Based on RHEL 9 (confirm when you sit) |
The decisive difference from multiple-choice certifications #
In a multiple-choice exam like CLF or KCNA you only had to pick the concept, but RHCSA has you perform tasks directly on an empty system, and a grading script inspects the resulting state. So “how” matters more than “why,” and if your hands are slow you’ll run out of time. In particular, with no internet you can’t look at Stack Overflow or blogs, so the habit of finding things in man pages quickly is what earns your points.
Your work must survive a reboot #
The most common cause of lost points on RHCSA is settings that disappear after a reboot. Mounts must go in fstab, services must be enabled, and the network must be left as a permanent NetworkManager configuration. Whether your work persists even when the system reboots before grading is what decides a pass. So this series covers making things permanent alongside every task.
Exam domains #
The RHCSA scope is laid out by domain in the official exam objectives (EX200 objectives). This series maps to them as follows.
| Domain | Series mapping |
|---|---|
| Essential tools and shell scripting | #2 , #3 |
| Boot and system operations | #4 , #9 |
| Local storage and file systems | #5–#7 |
| Packages and networking | #8 , #10 |
| Users and security | #11–#13 |
| Containers | #14 |
Storage (LVM and file systems) and security (users, firewalld, SELinux) have the most tasks, making them the core domains that decide a pass.
Study strategy #
1) Don’t read — type it yourself #
RHCSA pays out in proportion to how well it’s in your hands. Keep a VM running RHEL 9 or a compatible distribution (AlmaLinux or Rocky Linux), perform every task in the posts yourself, then reboot and confirm it persists.
2) Make man pages your weapon #
With no internet, man pages are your only reference. Build the habit of finding keywords with man -k (apropos) and finding examples within a man page with /EXAMPLE. The configuration example files under /usr/share/doc (for LVM, autofs, and the like) are a big help in the exam.
3) Always confirm that it’s permanent #
Every time you finish a task, ask yourself “does this survive a reboot.” Verifying fstab with mount -a and checking services with systemctl is-enabled is the habit that prevents lost points.
4) Save mock exams for the back half #
After one loop through this series, you’ll find a full-scale mock exam in #16. At that point, solve it against the clock and loop back through the domains where you came up short.
Registration and the testing environment #
Registration steps #
- Buy EX200 or a Red Hat Learning Subscription on the Red Hat training portal
- Choose your delivery method — a test center (Kiosk) or Red Hat Remote Exam (your own PC + live USB boot)
- Book your exam date, and for a Remote Exam, run the system compatibility check beforehand
Preparing for the Remote Exam #
- ID — A passport with English Romanization is safest
- Testing environment — Clear the desk, use a single monitor, and block outsiders from entering
- Boot environment — The Remote Exam boots a provided live image from USB, so you need a bootable PC and a stable wired network
Wrap-up #
What this post locked in:
- RHCSA (EX200) is the RHEL system administrator’s hands-on certification — an exam where you perform tasks directly on an empty system
- 2.5 hours / 210 of 300 (70%) / valid 3 years / no internet — only man pages and local docs are allowed
- Exam domains — essential tools and scripting, boot and operations, storage and file systems, packages and networking, users and security, containers
- Study strategy — type it yourself. Make man pages your weapon. Always confirm it’s permanent. Save mock exams for the back half
- The trap that decides a pass — settings that disappear after a reboot (fstab, enable, permanent networking)
Next — essential tools #
The exam structure is set. Now we go into the shell tools that form the foundation of every task.
In #2 Essential tools: bash, vi, redirection, find/grep, archive, ssh, we’ll type our way through the shell fundamentals that decide the speed of RHCSA work — I/O redirection and pipes, finding files with find and grep, tar and gzip archives, and ssh remote access with scp transfers.
