Replicas — Certified Kubernetes Administrator (CKA) Practice Questions
Replicas refers to the number of identical pod instances that a controller such as a Deployment or ReplicaSet should maintain running at any given time to satisfy availability and load requirements. The ReplicaSet controller continuously reconciles the actual running pod count against the desired replica count, creating or deleting pods as needed. CKA candidates must know how to scale workloads both imperatively and declaratively, understand how the Horizontal Pod Autoscaler can adjust replica counts based on metrics, and recognize the interaction between replica counts and PodDisruptionBudgets during disruption events.
