A team runs a CPU-intensive application. They want to ensure that the application gets a guaranteed amount of CPU and is not throttled below that amount, but they also want to allow it to burst above that amount if the node has spare capacity. Which resource configuration should they set?

Set a CPU request but no CPU limit

Set both CPU request and limit to the same value

Set neither CPU request nor limit

Set a CPU limit but no CPU request

A team runs a web service on a Deployment with 3 replicas. They want to automatically scale the number of replicas based on CPU utilization. They have set CPU requests on the containers. Which Kubernetes resource should they create to achieve this?

A ClusterRole and ClusterRoleBinding
