LFCS vs RHCSA: which Linux admin exam should you take?
By LearnSome.tech · Published 2026-11-11
TL;DR
Take the RHCSA if your job is in Red Hat Enterprise Linux environments, because an RHCSA is able to perform the core system administration skills required there. The LFCS exam is independent of distribution-specific tasks and requires solving multiple issues from a command line running Linux, and candidates have 2 hours to complete the tasks. Red Hat's RHCSA exam is a hands-on, practical exam that requires you to undertake real-world tasks, based on Red Hat Enterprise Linux 10, and configurations must persist after reboot without intervention.
What is the difference between LFCS and RHCSA?
The LFCS exam is independent of distribution-specific tasks, so selecting a platform in the exam preparation checklist is no longer required. By contrast, the RHCSA exam is based on Red Hat Enterprise Linux 10. Red Hat says the RHCSA certification is designed for experienced Red Hat Enterprise Linux system administrators seeking validation of their skills.
The Linux Foundation developed the LFCS to help meet the increasing demand for Linux administration talent, with items that simulate on-the-job tasks faced by sysadmins. There are no prerequisites for the LFCS exam. For the RHCSA, Red Hat asks that you have taken RH124 and RH134, or the RH199 rapid track, or have comparable work experience on Red Hat Enterprise Linux. You must be an RHCSA to become a Red Hat Certified Engineer in Enterprise Linux.
So let the job decide: if the servers you run, or the roles you apply for, use Red Hat Enterprise Linux, the Red Hat exam is closer to your daily work.
How do the LFCS and RHCSA exams run?
The LFCS is an online, proctored, performance-based test that requires solving multiple issues from a command line running Linux, with 2 hours to complete the tasks. To pass the LFCS, a score of 67% or above must be earned. Proctors watch remotely through streaming audio, video and screen sharing feeds. During the LFCS you may use man pages and documents installed by the distribution, if they are accessed from within the Linux server terminal on which the exam is delivered.
Red Hat describes the RHCSA as a hands-on, practical exam that requires you to undertake real-world tasks. Internet access is not provided, and you may not bring any hard copy or electronic documentation into the exam. For most exams, the documentation that ships with the product is available during the exam. Red Hat says you can test in-person or remotely.
| Item | LFCS | RHCSA |
|---|---|---|
| Task style | Command-line tasks | Real-world tasks |
| Platform | Not distribution-specific | Red Hat Enterprise Linux |
| Delivery | Online, proctored | In person or remote |
| Docs allowed | Man pages, distribution docs | Docs that ship with the product |
What does each exam cover?
The LFCS gives Operations Deployment 25% and Networking 25% of the exam. Storage and Essential Commands carry 20% each, and Users and Groups carries 10%. Its competencies also include managing virtual machines with libvirt, creating and managing containers, and implementing reverse proxies and load balancers.
RHCSA exam candidates should be able to accomplish the listed tasks without assistance. These have been grouped into several categories, such as configure local storage, manage basic networking and manage security. Study points include restricting network access using firewalld and firewall-cmd, and setting enforcing and permissive modes for SELinux. You must also manually interrupt the boot process in order to gain access to a system, and install and remove Flatpak software packages. Read both official objective lists side by side before you choose an exam.
Is RHCSA harder than LFCS?
Red Hat says its certification is highly regarded due to its challenging nature, and that its exams are about performing hands-on tasks as opposed to multiple-choice questions. The LFCS is also performance-based, with items that simulate on-the-job tasks and scenarios faced by sysadmins in the real world.
Practise checking every mount, SELinux setting and firewall rule after a reboot, not only straight after you make the change. The LFCS competencies range from basic Git operations to configuring bridge and bonding devices and packet filtering, port redirection, and NAT. Pick the exam that matches the systems you run rather than the one you expect to be easier.
What do LFCS and RHCSA cost, and how long do they last?
The LFCS certification exam on its own costs $445 and includes two exam attempts and 12 months to schedule and take the exam. Once you pass, the LFCS certification is valid for 2 years. If you need the retake, you must complete it within 12 months of the original purchase date, and there is no enforced wait period.
How should I practise Linux administration tasks before a certification exam?
Practise on throwaway virtual machines, work from a written task list, and check each result again after a reboot. Turn each objective into a task, such as creating a logical volume or setting an SELinux mode, and solve it without notes. Once enrolled in the LFCS, you get two simulation attempts, each with 36 hours of access from the start of activation. That simulation includes 20 to 25 questions that are exactly the same for every attempt and every user, unlike the actual exam.
Practise finding options on the machine itself, in man pages and installed documentation, rather than in a web search. Installing packages is not required to complete LFCS tasks, but if you decide to, you will want to be familiar with standard package managers such as apt, dpkg, dnf and yum. Time yourself on full mock sessions, and keep the last part of each one for checking work rather than starting new tasks. Keep running real systems after you pass, since in our view no exam replaces production experience.
Free official resources
The Linux Foundation's Introduction to Linux (LFS101) is a free training course for a working knowledge of Linux, using both the graphical interface and command line across the major distribution families. Its course material includes hands-on labs and assignments. The official LFCS page lists its domains and competencies, from operations deployment to users and groups. Red Hat's EX200 page publishes the objectives as study points and offers a free assessment to find the course that best supports your preparation.
From our labs
In our RHCSA course, you tell a runtime change from a persistent one for mounts, services, firewall rules and SELinux modes, and check each the way the exam grader does: after the reboot. A later lab has you read an AVC denial and tell whether it needs a port label, a boolean or a file label.
