You have an application running on a GKE cluster. Your application has a stateless web frontend, and has a high-availability requirement. Your cluster is set to automatically upgrade, and some of your nodes need to be drained. You need to ensure that the application has a serving capacity of 10% of the Pods prior to the drain. What should you do?

A. Configure a Vertical Pod Autoscaler (VPA) to increase the memory and CPU by 10% and set the updateMode to Auto. B. Configure the Pod replica count to be 10% more than the current replica count. C. Configure a Pod Disruption Budget (PDB) value to have a minAvailable value of 10%. D. Configure the Horizontal Pod Autoscaler (HPA) maxReplicas value to 10% more than the current replica count.
