You have a Kubernetes Deployment manifest but no infrastructure. What should you do to deploy the application?

To deploy a Kubernetes application when no infrastructure exists, you first need to provision a Kubernetes cluster. The gcloud command-line tool is used for interacting with Google Cloud resources, including creating Google Kubernetes Engine (GKE) clusters. Once the cluster is operational, kubectl is the standard command-line tool for interacting with Kubernetes clusters, including creating, updating, and deleting Kubernetes objects like Deployments, Services, and Pods from a manifest file. The incorrect options propose using kubectl to create a Kubernetes cluster, which is not its function; kubectl manages resources within a cluster, not the cluster itself. Similarly, Deployment Manager is used for templated infrastructure deployments on Google Cloud, not for deploying Kubernetes application manifests directly.
