   A media company has a legacy video-processing application that runs on a single large VM. The application is difficult to update because a small change requires a full redeployment, and the company wants to adopt a more modular approach. The team wants to improve deployment speed and enable independent scaling of different processing stages. What is the most effective modernization strategy?

   • AContainerize the entire application as a single container and deploy it to Cloud Run.
   • BUse a configuration management tool to automate the deployment of the application on the existing VM.
   • CBreak the application into microservices, package each as a container, and orchestrate them with GKE.
   • DMove the application to a larger VM to handle increased processing demand.

   A company runs a legacy application on a VM. The application is monolithic and has not been updated in years. The team is considering containerizing the application to improve deployment speed and resource utilization. What is a key challenge they should consider when moving from VMs to containers?

   • AContainers are less portable than VMs.
   • BThe application may have dependencies on the VM's operating system that are not captured in a container image.
   • CContainers require more memory than VMs because they include a full operating system.
   • DContainers cannot be used for monolithic applications.

   A company is running a stateful application that requires persistent storage. The application is currently running on a single VM, and the team wants to migrate it to GKE to improve scalability and reduce operational overhead. However, they are concerned about the complexity of managing stateful workloads in Kubernetes. What is the most appropriate approach?

   • AUse Cloud Run to run the stateful application.
   • BUse GKE with StatefulSets and persistent volumes to manage the stateful application.
   • CUse GKE but run the application as a single replica to simplify state management.
   • DKeep the application on the VM and do not migrate to GKE.

   A financial services company is modernizing a customer-facing web application. The development team wants to ensure that the application runs identically on a developer's laptop and in the production environment in Google Cloud. They also want to automate the deployment process to reduce the risk of human error. What should they do?

   • ACreate a VM image of the production environment and distribute it to developers.
   • BCreate a container image for the application and use GKE to manage deployments and rollouts.
   • CUse a configuration management tool to synchronize the production environment with developer laptops.
   • DDeploy the application directly from the source code repository to production using a CI/CD pipeline.

   In terms of resource usage, how do containers typically compare to virtual machines?

   • AContainers use more memory because they duplicate the operating system for each instance
   • BContainers and VMs have identical resource usage
   • CContainers require more storage because they include a hypervisor
   • DContainers are more lightweight because they do not include a full guest operating system
