CKA study guide: how to prepare for a hands-on exam
The CKA is a 2-hour exam of 15–20 tasks performed in live Kubernetes clusters, with 66% needed to pass. Studying for it is less about reading and more about repetition at the command line. This CKA study guide turns the Linux Foundation’s official curriculum into a plan.

Start from the official curriculum
Everything in your plan should map to the five domains the Linux Foundation publishes, and to their weight. Troubleshooting alone is 30% of the exam — almost a third of your study time belongs there.
Check the version too. The exam is based on Kubernetes v1.35. Commands, API versions and defaults change between releases, so prefer material that names the version it was written for.
- Troubleshooting — 30%
- Cluster Architecture, Installation & Configuration — 25%
- Services & Networking — 20%
- Workloads & Scheduling — 15%
- Storage — 10%

Topics to cover, domain by domain
A useful checklist is the chapter list of the Linux Foundation’s own CKA preparation course, Kubernetes Fundamentals (LFS258), which the Linux Foundation says provides “the skills and knowledge also tested” by the CKA. Its chapters cover:
- Installation and configuration, and Kubernetes architecture
- APIs and access, and API objects
- Managing state with Deployments; Helm and Kustomize
- Volumes and data
- Services and Ingress
- Scheduling
- Logging and troubleshooting
- Custom Resource Definitions
- Security and high availability

Practise in a real cluster, not on paper
Every task on the exam is done on a designated host, and the grader checks the state of the cluster afterwards. The only preparation that transfers directly is doing the same kind of work: create objects, change them, break them on purpose and repair them.
Make troubleshooting a daily habit rather than a final chapter. Take a working setup, introduce a fault — a wrong label selector, a stopped component, a missing permission — and find it from the symptoms alone. That is the skill a 30% domain rewards.
Work through tasks completely. Because the exam scores outcomes, a half-finished task can cost its full value; practise finishing and verifying, not just starting.

Learn the documentation you are allowed to use
During the exam you may open the Kubernetes documentation, the Kubernetes blog, the Helm documentation and, for the CKA, the Gateway API documentation. You must not open external search results.
Study with the same restriction. Instead of searching the web when you are stuck, find the answer in kubernetes.io/docs, and learn where the example manifests for common objects live. On exam day, knowing where a page is saves minutes that reading it from scratch would cost.

Train for the clock
2 hours for 15–20 tasks means six to eight minutes per task on average. Build speed with kubectl — generating manifests from the command line instead of typing them, and moving to the designated host each task names without losing time.
In timed practice, skip a task that stalls you and come back later. A task left until the end costs less than three tasks you never reach.

Use the two simulator sessions deliberately
The exam registration includes two simulator sessions, each with 36 hours of access and a set of 17 questions. Use the first early, to see which domains you are weak in, and keep the second for the final week as a dress rehearsal under time pressure.

How long to study
The Linux Foundation’s sample curriculum path suggests that, depending on your experience, the certification can be earned in 3–6 months with its courses plus additional study and practice. It also notes that its courses are not required or prerequisites for the exam.
If you already administer clusters at work, your gap is likely exam technique and the domains you rarely touch. If you are new to Linux, budget extra time: the Linux Foundation recommends familiarity with Linux and the command line before its Kubernetes Fundamentals course.

Where knowledge questions fit
Reading and questions cannot replace hands-on practice for the CKA, but they help with the layer underneath: understanding why a Service does not route or what an etcd backup contains before you spend lab time on it.
In Certsqill’s CKA question bank, every question explains each answer option, weighted the way the Linux Foundation weights the exam.
CKA study guide: questions people ask
What should a CKA study guide cover?
The five official domains in proportion to their weight — troubleshooting 30%, cluster architecture and installation 25%, services and networking 20%, workloads and scheduling 15%, storage 10% — plus hands-on practice and time management. Source: Linux Foundation, checked 9 October 2026.
Can I pass the CKA by reading alone?
It is unlikely to be enough: the exam consists of tasks you perform in live clusters, scored on the result. Reading helps you understand; only practice builds the speed.
Which Kubernetes version should I study?
The one the exam uses — currently Kubernetes v1.35, according to the Linux Foundation, checked 9 October 2026.
Is an official course required before the CKA?
No. The CKA has no prerequisites, and the Linux Foundation states that its courses are not required to take the exam.
