CKA Exam Details: What to Expect
Let's get down to the nitty-gritty of the CKA exam. The exam is performance-based, meaning you'll be given a set of tasks that you need to complete in a live Kubernetes cluster. You'll need to use your knowledge of Kubernetes concepts and command-line tools to solve these tasks within the given time. The exam consists of approximately 15-20 tasks and you'll have 2 hours to complete them. This is a timed exam, so time management is crucial. The tasks cover a wide range of Kubernetes topics, including: core concepts, like pods, deployments, services, and namespaces; scheduling and resource management, including node selection, resource quotas, and limits; networking, including ingress, service discovery, and network policies; storage, including persistent volumes, persistent volume claims, and storage classes; troubleshooting and debugging, including logging, monitoring, and debugging tools; application lifecycle management, including deployments, upgrades, and rollbacks; security, including role-based access control (RBAC), security contexts, and network policies. You'll be using a command-line interface (CLI) and a text editor during the exam, so you'll need to be proficient with these tools. The passing score for the CKA exam is 74%. This means you need to get a significant portion of the tasks correct to pass. And, of course, the exam is proctored online, so you'll need a stable internet connection, a webcam, and a quiet environment. Before you can schedule the exam, you need to purchase a voucher from the CNCF. The voucher includes one exam attempt and access to the official Kubernetes documentation. Make sure to review the exam curriculum and objectives before you start preparing. This will help you focus your studies and ensure that you cover all the necessary topics. Getting familiar with the exam environment is also important. This means getting comfortable with the command-line interface, text editor, and the Kubernetes documentation. You are allowed to use the official Kubernetes documentation during the exam, which can be a lifesaver.
