The Linux Foundation worked with industry experts and the Linux kernel 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 tasks from a command line running Kubernetes. Candidates have 2 hours to complete the tasks.


The exam is based on Kubernetes v1.34.
The CKA exam environment will be aligned with the most recent K8s minor version within approximately 4 to 8 weeks of the K8s release date.

About the CKA
The CKA was created by the Linux Foundation and the Cloud Native Computing Foundation (CNCF) as a part of their ongoing effort to help develop the Kubernetes ecosystem. The exam is online, proctored, performance-based test that requires solving multiple tasks from a command line running Kubernetes.


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). Each CKA simulator session has 17 questions, and you will receive a different set of questions (17 total) in each attempt. The simulation will provide graded results.

The practical, performance-based format of the CKA exam is a game changer for technical IT certifications. Unlike standard tests, it truly validates both theoretical understanding and hands-on skills. My Kubernetes proficiency improved drastically during my preparation. The experience was so valuable that, after discussing it with my coordinator, I will be leading a technical session for our entire DevOps team, to share the concepts I learned and my preparation journey. It was truly an excellent experience!
Dec 2025
It's as close to reality as an exam can get! Tough questions, but I loved it. These types of certificates are actually worth obtaining, as simply regurgitating some text will not get you through.
Dec 2025
Compared to taking the CKA exam years ago, the questions are far clearer than I can remember. There are tips for common questions, and commands/concepts that are likely out of scope. The ExamUI is nice in that it provides great detail, and makes all key information easily copyable, as well as quick to reference. I felt like it allowed me to focus on the core concepts and task at hand.
Oct 2025
The practical problem-solving exam is fantastic. I think preparing for this type of exam is a much better learning experience than preparing for multiple-choice exams.
Oct 2025
The exam itself does not test your memory, but it tests your understanding of Kubernetes which I think is great. It would definitely give all those who pass the certification exam a good reputation.
Aug 2025
Hands-on exam is the best. It is fun to study, fun to practice, and fun to do the exam. Because of this, preparing for the exam has given me invaluable experience on the subject matter, so whether I pass or not, embarking on this certification I feel much more prepared than before.
Aug 2025
It gave me a great opportunity to pause and dedicate time to learning new Kubernetes concepts, while strengthening my overall skills. As an expert, it’s easy to overlook this since you’re already working on related tasks day to day, but I believe sharpening your skills is essential.
Aug 2025
Practical, lab based exams beat multiple-choice hands down for depth of knowledge required. I feel that the certification you get from a lab based exam is worth more than a multiple-choice exam.
Aug 2025
The questions are realistic, and give you the confidence to handle real world issues with Kubernetes managed workloads.
Jul 2025
The hands-on nature of the exam pushes me to get proficient with the subject matter, which is not the same for other multi-choice exams that focus only on concepts. I love that about the CKA/AD/S exams.
Jul 2025
I love the lab style. I was able to clearly understand the problems, and how to apply real world fixing.
Jun 2025
The new version of the exam really helps towards studying cool, modern things about Kubernetes. I found a lot of things that I will definitely use in work projects, as well as answers to many questions. In addition, this exam is the only source of truth in terms of understanding how Kubernetes really works under the hood. No book, nor course will ever help you understand the whole Kubernetes core and ecosystem like this certification does.
Jun 2025
What I like the most about the CKA exam is the practical and real-world scenarios, cloud-native environment, coverage of Kubernetes concepts, encouraging command-line confidence, and boosting career value.
May 2025
I particularly appreciated the hands-on labs, which truly tested my practical Kubernetes skills. This exam format felt incredibly relevant and effective for validating real-world abilities.
May 2025
What I liked most was that the exam matched the topics they said it would cover, and the questions felt like real-world situations you’d actually run into when working with Kubernetes. It wasn’t just theory, it tested practical, useful skills.
Apr 2025
It's challenging, and gives you a feel of real-life situations. Someone who is certified definitely knows how to operate Kubernetes.
Apr 2025
I love that almost all the tasks are scenarios you could encounter in real life when working with Kubernetes. The multiple-choice questions are not just meaningless as in other exams.
Mar 2025
I like the availability, and the various date choices as to when our exam can be scheduled. The exam is well organized, and there are nice proctors, thank you!
Mar 2025
Depth of the material, and no multiple-choice questions, I wish all exams were like this.
Mar 2025
Although the exam was challenging, I appreciated the opportunity to work on real-world scenarios that tested my skills in Kubernetes, Service, and Networking. The exam covered a wide range of topics, which allowed me to demonstrate my understanding of different Kubernetes concepts and tools. Additionally, the use of practical tasks made the experience more hands-on, and reflective of real-life situations.
Feb 2025
I appreciated how the exam was well-structured and clearly aligned with what we learned. The questions were fair, and I liked that there was a good mix of conceptual and application-based problems. It really tested my understanding, rather than just memorization.
Jan 2025
I enjoyed the practical tasks. The skills tested are really in line with what I would expect from a holder of this certificate, and is good proof of understanding this topic I believe.
Jan 2025
Test environment was excellent, and very convenient, especially the question layout and important details highlighted for easy copy and paste, and relevant documentation links above every question. It's a pure test of knowledge, not how fast you can drag your mouse, or type away in the Kubernetes documents.
Jan 2025
The presented scenarios are great examples of how to test someone's skills. They are complex scenarios with simple solutions, that is, if you know what you're doing. If on the other hand you don't know, there is no way you can slip your way through with sheer luck. Good job on that.
Jan 2025
Great exam as a new Kubernetes beginner. The feeling of doing some tricky tasks with very limited time, reflecting real world work situations in an exam is what many other certification exams lack these days. I feel that the CKA certification exam needs to get much, much more recognition and aspiration.
Jan 2025
The questions were put up systematically, the hints were the important ones that help me get the tasks done quickly, the copy-paste mechanism lets me copy the words and the context of the question which is the best, this gives short info on the all-over task that needs to be performed.
Dec 2024
I really like how hands-on this course is, the certification is different to most in that regard. After completing this certification, I definitely feel confident walking into a job as a K8s Administrator, and to successfully do the job.
Dec 2024
The journey leading up to the exam was the most rewarding. I was forced to dive deep into the Kubernetes topics, and to truly master the material - this is not something that I have had to do for many other comparable certification exams.
Dec 2024
The CKA exam was a perfect combination of testing my knowledge of Kubernetes, my understanding of commands and how to issue them to get the desired results, and my understanding of the components of Kubernetes itself. Well thought-out and resourced exam in a great testing environment.
Dec 2024
The questions were very well laid out and clear, and definitely cover what a day-to-day cluster administration entails. Definitely a very valuable certification.
Nov 2024
Even though I am quite proficient in K8s, the limitation of only being able to use the documentation, and the breadth of the topics, forced me to look at some topics in more detail than I would in my daily work. I am sure this has broadened my understanding of K8s, and will come in handy one day.
Nov 2024
The hands-on nature of the exam and practical questions are refreshing for certifications. Along with the use of documentation, I feel that the exam is more "real world" than others I have seen.
Nov 2024
The exam is well-designed to guide you through key topics, encouraging a deeper understanding of the material. Each section is structured to reinforce specific concepts, ensuring candidates not only cover essential knowledge areas, but also internalize critical skills required for the field.
