Where from can I get a list of differences between CKA and CKAD ?
The main difference between these two exams is that CKA tests not only require knowledge of Kubernetes API primitives. The CKA exam also has things related to Kubernetes internals such as etcd, tls bootstrap, and kubelet. While CKAD is solely dedicated to concepts such as Deployments, DaemonSets, Pods, and other API primitives, we can consider it as a lightweight version of a CKA exam.
