KLCP case studies
KLCP · Put your knowledge to work in context.
The Kubernetes and Cloud Native Associate (KCNA) is an entry-level certification from the Cloud Native Computing Foundation (CNCF) that validates foundational knowledge of Kubernetes and the broader cloud native ecosystem. It suits developers, operations staff, students, and technical managers who need working literacy in containers and orchestration rather than deep hands-on cluster administration. The exam samples four areas: Kubernetes fundamentals (the largest share), container orchestration concepts, cloud native application delivery, and cloud native architecture. Expect conceptual multiple-choice and multiple-select items on pods, workloads, services, namespaces, scheduling basics, container runtimes, CI/CD and GitOps ideas, observability, and the CNCF project landscape. The KLCP case studies are 5 cases and about 2,514 words.
