1Z0-1072-26 Compute Practice Question
You are managing a Kubernetes cluster on OCI (OKE) and need to upgrade the Kubernetes control plane version. What happens to the existing worker nodes when you perform a control plane upgrade?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Worker nodes continue to run workloads, but you must manually or via node pool upgrades bring them to the matching version.
When you upgrade the control plane in OKE, the worker nodes continue running workloads normally, but they should eventually be upgraded to remain within supported version skew limits.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The cluster becomes completely inaccessible, and all pods are evicted permanently.
Why it's wrong here
Control plane upgrades in managed Kubernetes services maintain control plane availability and do not destroy pods.
- ✗
Control plane upgrades are blocked until all worker nodes are upgraded first.
Why it's wrong here
Control plane is upgraded independently before worker nodes.
- ✗
All worker nodes are automatically terminated and recreated with the new version.
Why it's wrong here
Worker nodes are not automatically terminated during a control plane-only upgrade.
- ✓
Worker nodes continue to run workloads, but you must manually or via node pool upgrades bring them to the matching version.
Why this is correct
Control plane and worker node upgrades are decoupled in OKE; worker nodes must be upgraded separately.
