How hard is CKAD?
Linux Foundation / CNCF classifies CKAD at the intermediate level. It is hands-on tasks against live clusters, open book against the kubernetes docs, sat in 120 minutes. No invented pass rates anywhere on this page.
The short answer
Certified Kubernetes Application Developer is a mid-level exam. It assumes working familiarity with the field it covers, and candidates coming from adjacent roles usually need to close real gaps rather than review. Linux Foundation / CNCF classifies it at the intermediate level, and the format is hands-on tasks against live clusters, open book against the kubernetes docs, sat in 120 minutes.
With a year or two of hands-on exposure to the subject area, preparation is mostly structured review plus practice under time pressure. Coming in cold, plan for meaningfully more study time and lean on the objectives to find what you have never touched.
What actually makes it hard
Interactive items, not just multiple choice.
Entirely hands-on: tasks in a terminal against live clusters, open book against the Kubernetes documentation. No multiple choice at all. These take longer than multiple-choice questions and punish rote memorization, because you have to do the task rather than recognize an answer.
Breadth across domains.
The blueprint spans 5 domains, and the heaviest, Application Environment, Configuration and Security, is 25% of the exam. You cannot skip a domain and rely on the rest; the weighting reaches everything.
The clock.
15 to 20 hands-on tasks questions in 120 minutes leaves little room to dwell. Time pressure is a skill of its own, and it is the one thing reading can never prepare you for. Timed practice can.
Where the weight sits
Difficulty is not spread evenly. Linux Foundation / CNCF publishes the domain weightings, and they tell you where your study time buys the most points:
- Application Environment, Configuration and Security25%
- Application Design and Build20%
- Application Deployment20%
- Services and Networking20%
- Application Observability and Maintenance15%
