Your existing application running in Google Kubernetes Engine (GKE) consists of multiple pods running on four GKE n1-standard-2 nodes. You need to deploy additional pods requiring n2-highmem-16 nodes without any downtime. What should you do?

A. Use gcloud container clusters upgrade. Deploy the new services. B. Create a new Node Pool and specify machine type n2-highmem-16. Deploy the new pods. C. Create a new cluster with n2-highmem-16 nodes. Redeploy the pods and delete the old cluster. D. Create a new cluster with both n1-standard-2 and n2-highmem-16 nodes. Redeploy the pods and delete the old cluster.
