Learn how to prepare for—and pass—the Kubernetes and Cloud Native Associate (KCNA) certification exam. This practical guide serves as both a study guide and point of entry for practitioners looking to explore and adopt cloud native technologies. Adrián González Sánchez and Jorge Valenzuela Jiménez teach you not only the core technology fundamentals, but also the community and industry that KCNA serves.

With the meteoric rise in cloud adoption, cloud native technologies such as Kubernetes have become the de facto industry standard. Other Kubernetes certifications—including KCSA, CKAD, CKA, and CKS—are all geared toward higher-level technical proficiency. The KCNA is the entry door to your cloud native journey, and the certification exam covers the cloud native environment generally as well as fundamental Kubernetes skills and knowledge.

KCNA is a multiple-choice, entry-level exam and offers everyone from students to those looking to make a career change a way to demonstrate the basic knowledge and skills of cloud native. KCNA will demonstrate a candidate’s basic knowledge of Kubernetes and cloud native technologies, including usage of API and kubectl commands, the high-level Kubernetes architecture, and understanding the ramifications of the cloud native landscape in domains such as security, storage, observability, GitOps, and service mesh. Overall, the exam is divided into five main parts covering Kubernetes and the wider cloud native landscape.

Kubernetes Fundamentals covers 46% of the questions and tests whether students understand the correlations among resources, such as containers, Pods, ReplicaSets, and Deployments. Additionally, this part of the exam explores how the scheduler works to create new replicas of an application, alongside top-level components of the Kubernetes architecture.

Finally, the last two exam parts explore the candidate’s knowledge of observability and application delivery tools. These sections highlight the usage of telemetry tooling such as Prometheus and OpenTelemetry, continuous integration and continuous delivery (CI/CD) fundamentals, GitOps functionalities with tools like ArgoCD, and cost management techniques.
