KCNA vs CKA: which certification should you take first?
By Ibrahim Yesilay · Published · Updated
KCNA is a multiple-choice exam on Kubernetes and cloud native fundamentals; CKA is a hands-on exam where you administer real clusters in a terminal. New to the ecosystem, start with KCNA. Already running clusters, you can go straight to CKA. Neither lists a prerequisite for the other.

How KCNA and CKA differ
KCNA (Kubernetes and Cloud Native Associate) is a multiple-choice exam in the Kubestronaut core group of the Golden Kubestronaut program, and CKA (Certified Kubernetes Administrator) is a performance-based, hands-on exam in the Kubestronaut core group. They are tested in different ways, which changes how you prepare as much as what you study. KCNA: Multiple-choice exam on foundational knowledge of Kubernetes and the wider cloud native ecosystem. CKA: Performance-based exam on installing, configuring and troubleshooting Kubernetes clusters: storage, workloads and scheduling, cluster architecture, services and networking. The table above sets format, questions, duration, passing score, price, validity, prerequisites and the number of domains side by side, each value read from the official Linux Foundation pages and dated.
A multiple-choice exam rewards knowing the concepts and recognising the correct statement among plausible ones. A hands-on exam rewards doing the task in a live terminal within the time limit. Few people prepare for both in the same way.
What KCNA and CKA cover
KCNA is organised into 4 domains and CKA into 5. The heaviest KCNA domain is Kubernetes Fundamentals (44%), while the heaviest CKA domain is Troubleshooting (30%). Domain weights come straight from each official certification page and show where the Linux Foundation expects most of your preparation time to go. If your own work sits mainly in one heavy domain of an exam, that exam will feel closer to your daily job; if the heavy domains are unfamiliar, plan more study time for that exam. The lists below give every domain with its weight, checked against the official pages on the date shown at the top of this page.
- KCNA: Kubernetes Fundamentals, 44% of the exam
- KCNA: Container Orchestration, 28% of the exam
- KCNA: Cloud Native Application Delivery, 16% of the exam
- KCNA: Cloud Native Architecture, 12% of the exam
- CKA: Storage, 10% of the exam
- CKA: Troubleshooting, 30% of the exam
- CKA: Workloads & Scheduling, 15% of the exam
- CKA: Cluster Architecture, Installation & Configuration, 25% of the exam
- CKA: Services & Networking, 20% of the exam
Who should take KCNA
KCNA suits people who are new to Kubernetes or to the cloud native landscape and want a structured first target. It tests whether you understand what the pieces are and how they fit together, rather than whether you can fix a broken cluster under time pressure. It is a sensible first exam for developers, students, managers, and anyone moving from traditional infrastructure who needs the vocabulary and the big picture before touching production clusters. KCNA is a multiple-choice exam with 4 domains, led by Kubernetes Fundamentals (44%), and it sits in the Kubestronaut core group of the program. The table above gives its questions, duration, passing score, price and validity with their sources. Choosing is easier when you compare the domain list with the work you actually did in the last month, and the official certification page remains the place to confirm the current curriculum before you book.
- You are new to Kubernetes and want to learn the concepts before the commands.
- You work around cloud native teams and need to follow the architecture conversation.
- You want an early, lower-pressure certification toward Kubestronaut.
- You prefer a multiple-choice format over live terminal tasks.
Who should take CKA
CKA suits people who install, configure and troubleshoot Kubernetes clusters, or who want to be able to. The exam is a set of tasks performed in a live command-line environment, and its largest domain is troubleshooting. Preparation is mostly hands-on repetition: building clusters, working with storage and networking, and fixing faults quickly. It fits platform engineers, SREs and system administrators more than someone who has only read about Kubernetes. CKA is a performance-based, hands-on exam with 5 domains, led by Troubleshooting (30%), and it sits in the Kubestronaut core group of the program. The table above gives its questions, duration, passing score, price and validity with their sources. Choosing is easier when you compare the domain list with the work you actually did in the last month, and the official certification page remains the place to confirm the current curriculum before you book.
- You operate or plan to operate clusters in your job.
- You are comfortable in a Linux terminal and with YAML.
- You want proof of practical skill, not only conceptual knowledge.
- You are ready to practise tasks against a clock rather than read about them.
Can you take both, and in which order?
Yes, you can take both, and both are among the five core certifications of the Kubestronaut title. The Linux Foundation lists no prerequisite for either, so the order is your choice. Taking KCNA first is the gentler route: the concepts it covers are the same ones CKA assumes you understand. If you already work with clusters every day, the KCNA content will feel familiar and you can reasonably start with CKA. Prerequisites as published by the Linux Foundation: KCNA: None. CKA: None. Each is listed as its own certification in the program, so passing one never counts toward the other. Whichever you choose first, book the exam only when you can answer questions across every domain, not just the heaviest one.
A practical way to decide is to read the KCNA domain list in the table section and ask whether any of it is unfamiliar. If most of it is, take KCNA first and use it as a map for what to learn. If you could explain all of it already, put your preparation time into CKA, where terminal speed is what separates a pass from a retake.
How GoldenKube helps with KCNA and CKA
GoldenKube is a free practice app for the multiple-choice certifications in the Golden Kubestronaut program. KCNA has a live GoldenKube question bank: every question comes with an explanation, you get instant feedback, and questions you miss come back for review until you have mastered them. CKA is a hands-on exam. GoldenKube offers practice only for multiple-choice exams, so there is no CKA practice here; terminal labs are planned but not available. You get 10 free guest answers, then a free account; no credit card is needed. Practice does not replace the official curriculum, and passing practice questions does not guarantee a pass on the real exam.
Use KCNA practice to find which concepts you still miss, then carry that knowledge into your CKA terminal preparation. For CKA itself, use the official curriculum and a real cluster of your own.
Verdict: KCNA or CKA first?
Take KCNA first if you are new to Kubernetes or want a concept-level first win; take CKA first if you already administer clusters and can work comfortably in a terminal. There is no prerequisite between them, so the choice depends on your experience, not on the rules. Most people on the Kubestronaut path take both eventually.

Frequently asked questions
Should I take KCNA or CKA first?
If you are new to Kubernetes, take KCNA first: it is multiple-choice and covers the concepts CKA builds on. If you already administer clusters, you can start with CKA. The Linux Foundation lists no prerequisite between the two.
Is KCNA easier than CKA?
They test different things. KCNA tests understanding through multiple-choice questions; CKA tests doing, through tasks in a live terminal. Which feels harder depends on whether you are stronger at concepts or at hands-on work, so compare the format rows in the table rather than relying on a single label.
Does KCNA count toward CKA?
No. They are separate exams with separate fees. KCNA does not replace or reduce CKA, although the concepts it covers help you prepare. Both count toward the Kubestronaut title.
Can I practise CKA on GoldenKube?
No. GoldenKube offers practice only for multiple-choice exams, and CKA is performance-based. Terminal labs are planned but not available. KCNA practice questions are available now.
Do I need both for Golden Kubestronaut?
Yes. Golden Kubestronaut requires all certifications in the program, and both KCNA and CKA are in it. See the Golden Kubestronaut page for the full list and the suggested order.
Where do I register for the exams?
Only through the official Linux Foundation certification pages, linked in the sources of this page. GoldenKube is an independent practice app and does not sell or schedule exams.
