The ability to administer and monitor a Kubernetes cluster is in high demand today. To meet this need, the Cloud Native Computing Foundation developed a certification exam to establish a system administrator's credibility and value in the job market to confidently work in a Kubernetes environment. The Certified Kubernetes Administrator (CKA) certification exam is different from the typical multiple-choice format of other professional certifications. Instead, the CKA is a performance-based exam that requires deep knowledge of the tasks under immense time pressure.

Kubernetes, as a runtime and orchestration environment for microservices, is widely-used among start-ups and large enterprises alike. As your organization ramps up on the number of applications, managing the Kubernetes clusters becomes a full-time job. That’s the role of a Kubernetes administrator. The person responsible for this job ensures that the cluster is an operational state, scales up the cluster by onboarding nodes, upgrades the Kubernetes version of the nodes to incorporate patches and new features, and is in charge of a backup strategy for crucial cluster data. To help job seekers and employers have a standard means to demonstrate and evaluate proficiency in developing with a Kubernetes environment, the Cloud Native Computing Foundation (CNCF) developed the Certified Kubernetes Administrator (CKA) program. To achieve this certification, you need to pass an exam.

This study guide walks you through all the topics covered to fully prepare you for the exam. Author Benjamin Muschko also shares his personal experience with preparing for all aspects of the exam.
