A team is creating an HPA for a Deployment that is part of a StatefulSet. The StatefulSet has 3 replicas. The team wants the HPA to manage the number of replicas. What is the correct target for the HPA?

The Service that fronts the StatefulSet

The ReplicaSet created by the StatefulSet

In an HPA, what is the purpose of the stabilization window (stabilizationWindowSeconds)?

To set the minimum number of replicas that must be running.

To prevent frequent scaling changes by waiting before applying a new scale decision.

To specify how often the HPA checks metrics.

To define the maximum number of replicas that can be created.

Which kubectl command deletes a HorizontalPodAutoscaler named 'web-hpa'?

kubectl delete autoscaler web-hpa

kubectl delete deployment web-hpa
