ExploreAbout this exam
The Kubernetes and Cloud Native Associate (KCNA) is CNCF's entry-level, vendor-neutral certification for people who want to prove they understand Kubernetes and the surrounding cloud native ecosystem before moving on to hands-on, role-based credentials. The source describes it as a pre-professional certification with no prerequisites and a beginner experience level, aimed at students, career changers and early-career engineers.
The exam is conceptual rather than performance-based: it is an online, proctored, multiple-choice test lasting 90 minutes. Weighting is Kubernetes Fundamentals 44%, Container Orchestration 28%, Cloud Native Application Delivery 16% and Cloud Native Architecture 12%. In practice that spans cluster architecture and core objects (pods, nodes, namespaces, the control plane, Deployments, Services, ConfigMaps), scheduling, networking, storage and troubleshooting, delivery concepts such as CI/CD and debugging, and architecture topics including observability, the CNCF project landscape and community collaboration.
Preparation options named in the source include the open-source curriculum CNCF publishes for the exam, a free Introduction to Kubernetes course, and the paid Kubernetes and Cloud Native Essentials (LFS250) course, which can be bundled with the exam. The exam costs $250 and includes one free retake.
What you'll study
About KCNA preparation
What is the exam format and how long do I get?
It is an online, proctored, multiple-choice exam with a duration of 90 minutes. There is no hands-on terminal or live cluster component, so you are answering knowledge questions rather than performing tasks under a time limit as you would on a practical exam.
How much does it cost and what does the fee include?
The cost is $250 and includes one free retake. That gives you two exam attempts in total, plus 12 months to schedule and take the exam. Bundles exist: exam plus the LFS250 course is listed at $299, and exam plus the THRIVE-ONE annual subscription at $495.
Are there any prerequisites?
No. The Linux Foundation page states plainly that there are no prerequisites for this exam, and it is listed at beginner experience level. Comfort with Linux command-line basics and container concepts helps you move faster, but nothing is formally required before you register.
How is the exam weighted across domains?
Kubernetes Fundamentals is 44%, Container Orchestration 28%, Cloud Native Application Delivery 16%, and Cloud Native Architecture 12%. Fundamentals alone is nearly half the score, so it deserves the most study time; architecture and delivery together still account for more than a quarter.
How long is the certification valid, and how long do I have to sit the exam?
You have 12 months to schedule and take the exam after purchase, and the certification itself is valid for two years once you pass. KCNA participates in the CARE program, which is CNCF's structure for simplifying certification maintenance and renewals.
How should I sequence my studying?
Start with Kubernetes architecture and core objects, since Fundamentals carries 44%. Move next to orchestration topics - networking, security, troubleshooting, storage - then delivery (CI/CD, debugging) and finally architecture (observability, the CNCF landscape, community). Front-loading the heaviest domain protects you if study time runs short.
Is the exam hard?
It is an entry-level conceptual exam, but published candidate reviews describe it as non-trivial: contributors with CKA or CKS experience report needing to re-read some questions. The challenge is breadth rather than depth - many topics, each tested at a foundational level. Surface-level memorization of a few kubectl commands is usually not enough.
What are the most common ways candidates underprepare?
Two recurring traps: treating it as a pure kubectl exam when it also covers the wider ecosystem, and skipping the non-Kubernetes projects. Candidates who come from a narrow operational background often lose points on the CNCF landscape and observability topics rather than on pods and Deployments.
What should I take after passing?
The source points to the Kubernetes and Cloud Native Security Associate (KCSA) for security-focused validation, or the Certified Kubernetes Administrator (CKA) as the next level. CKAD and CKS are also named as further CNCF credentials the KCNA is intended to prepare you for.
