Cluster-Upgrade — Certified Kubernetes Administrator (CKA) Practice Questions

Cluster upgrades involve incrementally updating Kubernetes components, starting with the control plane and then the worker nodes, to a newer version. The CKA exam tests candidates on using kubeadm to perform in-place upgrades, including draining nodes, applying the upgrade, and uncordoning nodes afterward. Understanding the version skew policy, which limits how far apart control plane and node versions can be, is critical to performing safe upgrades without breaking cluster functionality.
