The problem-solving exercises were great, but I also liked how the lecture content was organized to show the relationships between Kubernetes components at a glance. I think it will be a great reference not just for the exam, but also when using Kubernetes in practice. For now, I highly recommend this to anyone planning to take the CKA exam. I feel like I missed about two questions in the actual exam. · There were definitely parts (questions) where I got stuck while solving them. I should have clearly identified the cause of why that happened and known the solution. Example: The reason why a Pod wouldn't enter the running state even though there seemed to be no issues with the YAML script when adding a sidecar container. · I should have studied the related concepts and content broadly, not just the methods for solving the problems. Example: Troubleshooting the failure of kube-apiserver due to an etcd URL mismatch. It is good to learn extensively about the content and roles of each configuration item for Kubernetes elements, in addition to just the solutions. I will have to learn more about the areas I lacked while using Kubernetes in the field. Stay calm, study hard, and I hope you get a high score.
