CKA certification is a problem-solving exam, meaning you don’t have any questions but instead have a number of scenarios to troubleshoot.
The idea behind this approach is that you’re meant to have a certain level of understanding the Kubernetes components in order to successfully navigate and troubleshoot the k8s environment.
I like this approach. If I remember correctly, something similar needed to be done for an RHCSA exam I one did - instead of just learning a bunch of standard questions and answers, you were actually required to understand the RHEL operating system on quite a deep level.
Really enjoyed getting ready for the exam - the preparation course on A Cloud Guru came in really handy. Thanks to a combination of quizes and practice labs, you really get to test multiple aspects of understanding Kubernetes.
