An HPA is not scaling up a Deployment even though CPU usage is high. 'kubectl describe hpa' shows the condition 'ScalingActive' is 'False'. What does this condition indicate?

The HPA is scaling, but the Deployment is not updating its replicas.

The HPA has reached its maximum replica count and cannot scale further.

The HPA is paused and will not scale until it is resumed.

The HPA is unable to fetch metrics, so it cannot calculate the desired replica count.

Which HPA field allows you to control the maximum number of replicas that can be added in a single scale-up event?

spec.behavior.scaleDown.stabilizationWindowSeconds

spec.metrics[].resource.target.averageUtilization

spec.behavior.scaleUp.policies[].value

An HPA is configured to use a custom metric. The HPA is not scaling, and 'kubectl describe hpa' shows the event 'FailedGetPodsMetric'. What is the most likely cause?

The custom metrics API server is not reachable or is not returning the expected metric.

The Deployment's pods do not have resource requests defined.

The Deployment is not exposing the metric on the correct port.

The HPA's maxReplicas is set too low.

Which field in a HorizontalPodAutoscaler manifest defines the target CPU utilization percentage that triggers scaling?

spec.metrics[].resource.target.averageUtilization

spec.behavior.scaleUp.stabilizationWindowSeconds
