The CKS was created by the Linux Foundation and the Cloud Native Computing Foundation (CNCF) as a part of their ongoing effort to help develop the Kubernetes ecosystem. The exam is online, proctored, performance-based test that requires solving multiple tasks from a command line running Kubernetes.

Once enrolled you will receive access to an exam simulator, provided by Killer.sh, allowing you to experience the exam environment. You will have two simulation attempts (36 hours of access for each attempt from the start of activation). The simulation includes 20-25 questions that are exactly the same for every attempt and every user, unlike the actual exam. The simulation will provide graded results.
