What it validates, who it is written for, and the experience it assumes.
The Kubernetes and Cloud Native Associate (KCNA) certification is your entry point into the world of Kubernetes and cloud native technologies. It confirms your understanding of the fundamental concepts and principles that underpin modern cloud native ecosystems, from container orchestration to cloud native architecture. This certification is ideal for individuals starting their Kubernetes journey or those in non-technical roles who need a solid grasp of the cloud native landscape.
By earning the KCNA, you demonstrate to employers that you possess the foundational knowledge required to contribute effectively in cloud native environments. The exam covers key areas such as Kubernetes fundamentals, container orchestration, cloud native application delivery, and observability. As a vendor-neutral certification from The Linux Foundation, it provides a strong, unbiased foundation for career growth and flexibility, complementing other certifications you may hold.
The KCNA certification is designed for individuals who are new to Kubernetes and cloud native technologies, including students, developers, IT professionals, and those in adjacent roles like project managers or sales engineers. It is also suitable for professionals who want to validate their foundational knowledge before pursuing more advanced certifications like the CKA or CKAD. If you are looking to start a career in cloud native computing or need to understand Kubernetes concepts to better collaborate with technical teams, the KCNA provides a structured and recognized way to build and prove that knowledge.
While there are no mandatory prerequisites, The Linux Foundation recommends some familiarity with cloud native concepts and basic Linux command-line skills. The official KCNA learning path and free introductory courses can help you prepare. Basic understanding of cloud computing concepts; Familiarity with Linux command line and open source software; Interest in Kubernetes and containerization; Completion of the free Introduction to Kubernetes course or the Kubernetes and Cloud Native Essentials (LFS250) course is recommended

See how the coach worksThe KCNA is an entry-level certification that covers foundational Kubernetes and cloud native concepts. The CKA and CKAD are professional-level certifications that focus on hands-on administrative and application development skills. The KCNA can serve as a stepping stone to these more advanced certifications.
No, the CKA does not require the KCNA as a prerequisite. However, the KCNA can help you build the foundational knowledge needed to succeed in the CKA exam.
No, the KCNA exam is a multiple-choice exam. It tests theoretical knowledge of Kubernetes and cloud native concepts rather than practical, hands-on skills.
The KCNA exam includes one free retake. If you fail the exam on your first attempt, you can retake it once without additional cost. Further attempts may require purchasing a new exam voucher.
The KCNA is designed for individuals in roles such as cloud engineers, DevOps practitioners, site reliability engineers, and anyone working with cloud native technologies. It validates foundational knowledge that is valuable for roles that involve Kubernetes and containerized applications.
The KCNA certification is valid for two years. To renew, you must pass the current version of the KCNA exam or complete the renewal process defined by The Linux Foundation. Passing a higher-level exam like the CKA does not automatically renew the KCNA.
The official exam page lists the exam as available in English. For information about other language options, please refer to the official Linux Foundation website or contact their support team.

In front of every objective the practice pages are already there, free and without an account. This is one objective, opened.
60 questions on this objective, five to a page. Every range above is a real page, open now, with no account.
The curriculum tells you what is on the exam. Proving you know it is a different job — and it is the one the closed-book run does.
The whole bank is open. 5 questions to a page, every answer explained, and a discussion thread on each one.
Every objective, and every page range, is a link — so you can pick up exactly where you left off.
Short enough to finish, long enough to matter.
Not only which one is right — why the others are wrong.
Ask, answer, and vote. Every question has its own thread.
These are not trivia. Each one is written against a concept in the book, so when you get one wrong there is somewhere to go and find out why.

The pages shown here come from our AI-900 book — an example of how each concept is written in plain language and, where the idea needs one, drawn as a full page you can take in at a glance.

The look-alikes sit togetherThe pairs the exam tests are drawn side by side, so the difference is seen, not told.
Dual coding · PaivioYou are never asked to read a poster here — only to see how one is built. After that, every other page is legible at a glance.

This is the part that teaches. The illustration and the written explanation stay where they are while you work, so a scenario stops being a memory test and becomes something you can simply look at.

Where the exam is defined, scheduled and scored.
We link to them rather than repeat them, so nothing here goes stale behind them.
We build from the official skills outline, not from a summary of it — 13 objectives, 106 concepts written under them, and free questions against every one. When Linux Foundation changes the outline, this page changes with it.
That is the only question worth answering the night before, and no link answers it. You answer it by taking the questions with the book closed, and seeing what comes back.
