Certified Kubernetes Application Developer (CKAD)

The CKAD is a completely practical, performance-based exam that tests your ability to deploy and configure Kubernetes applications using the command line. Rather than taking a standard multiple-choice test, candidates have two hours to complete roughly 15-19 tasks inside a live Linux terminal.

No, you are restricted to using a command-line terminal within the exam environment, meaning you must be highly proficient with kubectl. You cannot rely on any web-based dashboards, though you are allowed to open one tab to reference the official Kubernetes documentation.

While the Certified Kubernetes Administrator (CKA) exam focuses heavily on installing, maintaining, and troubleshooting the cluster infrastructure, the CKAD focuses strictly on application deployment. The CKAD tests your ability to define network policies, configure persistent storage for apps, and manage scale and rolling updates.

You do not need to write complex YAML files from scratch, as you will have access to the official Kubernetes documentation during the exam. However, you must memorize how to use `kubectl` commands to generate YAML templates quickly, as time management is the biggest hurdle.
