Before OKE terminates or recycles a managed worker so Pods can move safely, what sequence does the platform use?
Select an answer to reveal the explanation.
Short Explanation
Cordon is the “closed” sign; drain is the orderly exit. OKE marks the node unschedulable, moves Pods elsewhere within the eviction grace period, then recycles—especially useful when cycling a pool for a new Kubernetes version.
Full Explanation
Official OKE node operations cordon a managed node (no new Pods) and then drain it (evict existing Pods to other workers) subject to an eviction grace period before termination or recycle. Enhanced clusters can cycle an entire node pool this way to pick up a new Kubernetes version or node property. Abrupt pool deletion, cluster-wide scale-to-zero, or deleting PVCs are not the documented safe replace path.
