An HPA has been created for a Deployment, but the number of replicas is not changing even under heavy load. The team suspects the HPA cannot read metrics. Which command should be used first to check the HPA's status and recent events?

kubectl get events --all-namespaces

An HPA is configured with a scaleUp policy of 'Pods' with a value of 4 and a periodSeconds of 60. The current replica count is 2, and the HPA calculates that it needs 10 replicas to meet the target. How many replicas will the HPA add in the first scale-up action?

2 replicas, bringing the total to 4

10 replicas, bringing the total to 12

8 replicas, bringing the total to 10

4 replicas, bringing the total to 6
