I'm preparing for the Certified Kubernetes Administrator exam after completing a comprehensive course. I'm working through mock exams now and plan to move on to more advanced practice scenarios. I've heard that newer exam versions place more emphasis on Helm, Kustomize, custom resource definitions, Calico and Flannel, cluster installation and upgrades, CNIs, CRIs, and Gateway API. Some of these topics receive only limited coverage in the labs I've used, with Helm seeming especially common. What should I do to build stronger hands-on knowledge in these areas, and are there any other newer topics I should add to my study plan? I'm somewhat familiar with Gateway API but would appreciate suggestions for what to focus on.

The areas you listed can all show up, so it’s worth having at least a practical working knowledge of each. The most valuable preparation is being able to navigate the official Kubernetes documentation quickly, since finding the exact syntax under time pressure matters a lot. Gateway API deserves extra attention because its documentation is organized separately from the main Kubernetes docs. If you can complete realistic practice scenarios quickly and confidently, you should be in good shape.
The separate Gateway API documentation catches many people out. Knowing where to search, along with using Ctrl+F effectively, is almost as important as memorizing the commands. If you’re already moving through the practice labs comfortably, you’re probably on the right track.
That’s helpful, thanks. I’ll spend more time on the Gateway API documentation and practice finding the relevant pages quickly.
