In response, the Cloud Native Computing Foundation (CNCF) developed the Certified Kubernetes Application Developer (CKAD) program to establish credibility and value in the job market. The exam is different from the typical multiple choice format of other certifications. It’s completely performance based, under immense time pressure, and requires deep knowledge of the tasks.
