Node Maintenance — Certified Kubernetes Administrator (CKA) Practice Questions
Node maintenance in Kubernetes involves safely taking a node out of service so that workloads are migrated before the node is patched, upgraded, or replaced. The primary tools are the cordon command, which marks a node unschedulable, and the drain command, which evicts all pods while respecting PodDisruptionBudgets. CKA candidates are tested on the correct sequence of steps to perform maintenance without causing application downtime, including how to return a node to service afterward with the uncordon command.
