Scaling — Certified Kubernetes Administrator (CKA) Practice Questions
Scaling in Kubernetes refers to adjusting the number of Pod replicas for a workload, either manually through kubectl scale or automatically through the Horizontal Pod Autoscaler (HPA). The CKA exam tests candidates on scaling Deployments and ReplicaSets, understanding how the scheduler places new Pods across nodes, and recognizing conditions such as insufficient resources that prevent scaling from succeeding. Knowing how to configure resource requests and limits is closely tied to scaling because the scheduler uses requests to determine Pod placement.
