It depends on your background and goals. If you are new to Kubernetes and cloud native concepts, an associate level certification like KCNA or a general cloud course can be a good starting point. If you already work with clusters, CKA is typically the first practitioner level exam, while CKAD is ideal if you focus on building and deploying applications. CKS is usually taken later by people who already hold CKA and want to specialise in security.
No, but it helps. You should be comfortable with the Linux command line, basic networking, and containers (for example Docker) before going too deep. Many learners build these fundamentals in parallel with Kubernetes by following a structured curriculum or bootcamp and doing lots of hands on labs.
You can learn most core concepts using local or temporary environments. Spin up a small cluster with tools like Minikube, Kind, or a free tier managed Kubernetes service. Then experiment with RBAC, network policies, Secrets, and image scanning on noncritical demo workloads. This gives you practical experience without risking real customer data or systems.
