The new CKA 2020 for Kubernetes v1.19 blueprint has an objective to, “Use Kubeadm to install a basic cluster.” While I haven’t taken the CKA v1.19 exam yet, based on the exam environment from Linux Foundation (image below), it doesn’t appear that creating a brand new cluster will be necessary in the exam. Instead, cluster ik8s is missing a node and I assume the task will involve gathering the information to add the node to the cluster.
