Free CKAD - Certified Kubernetes Application Developer Exam Questions and Answers
CKAD is unlike almost every other exam in this catalogue: there are no multiple-choice questions at all. It is 15 to 20 performance-based tasks solved at a real command line on a remote Linux desktop, remotely proctored, in 120 minutes at 66% to pass — a true percentage, though tasks carry different point values. It costs $445, which includes a free retake and two attempts at the Killer.sh simulator. The exam environment tracks Kubernetes closely, currently v1.35, and is updated within weeks of each release. Weighting is application environment, configuration and security 25%, then design and build, deployment, and services and networking at 20% each, with observability and maintenance 15%. The certification lasts two years.
