Infosys Devops Engineer interview questions

They asked about kubernetes and docker

You need to migrate a running application from one EKS cluster to another without downtime. How would you achieve this? Your GKE cluster is running out of resources due to high CPU utilization. How do you troubleshoot and scale it properly? A new developer needs access to view logs and pod details in a specific namespace. How do you configure RBAC for this? You have multiple workloads in a cluster, and some need to run on nodes with SSDs while others can run on standard disks. How do you enforce this using Kubernetes?
