The Linux Foundation worked with industry experts and the project’s community to identify the core domains and the critical skills, knowledge and competencies applicable to each certification. Performance-based exams were then developed based on the competencies that were identified.
Exam Details & Resources
This exam is an online, proctored, performance-based test that requires solving multiple issues from a command line running Linux. Candidates have 2 hours to complete the tasks. Please review The Linux Foundation certification Policies and FAQ below.
About the LFCS
LFCS was developed by The Linux Foundation to help meet the increasing demand for Linux administration talent. The exam consists of performance-based items that simulate on-the-job tasks and scenarios faced by sysadmins in the real world. The exam is independent of distribution-specific tasks, therefore selecting a platform in the exam preparation checklist is no longer required.

Once enrolled you will receive access to an exam simulator, provided by Killer.sh, allowing you to experience the exam environment. You will have two simulation attempts (36 hours of access for each attempt from the start of activation). The simulation includes 20-25 questions that are exactly the same for every attempt and every user, unlike the actual exam. The simulation will provide graded results.

Prerequisites
There are no prerequisites for this exam.
Reviews
Feb 2025
I liked preparing for the exam. A wide range of Linux topics where covered that I had not normally encountered in my daily work, but it was valuable knowledge to have.

Linux Foundation is one of the best exams to test your skills, and advance your career. I was honored to have the opportunity to write a test, and it all went smoothly!
Feb 2024
It was challenging and pushed me to improve my skills. I find myself using these skills in my day-to-day work.
Mar 2024
I liked the hands-on approach to the exam. The exam is based on application of the different concepts rather than the theory behind it.
Dec 2023
A hands-on exam testing close to real-life scenarios. Every assignment runs in a different VM so one assignment doesn't affect another one, thereby reducing stress and testing course units individually.
Jul 2023
The exam is thorough and reaches beyond what you might see in related courses to make sure you know how to get around on a system you're familiar with but not fully knowledgeable of.
Sep 2023
It is like troubleshooting in real life. I liked the topics really seen on the course that were included in the exam.
