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
✓
Multiple node pools with multiple nodes
Horizontal Pod Autoscaler (HPA) scales pods based on metrics. Node pools with multiple nodes provide redundancy. Cluster auto-scaling adds nodes as needed. StatefulSets are for stateful apps, not high availability by themselves. Regional clusters provide multi-zone HA.
