Câu 29: Google Cloud Professional Cloud Network Engineer

Your company's web server administrator is migrating on-premises backend servers for an application to GCP. Libraries and configurations differ significantly across these backend servers. The migration to GCP will be lift-and-shift, and all requests to the servers will be served by a single network load balancer frontend. You want to use a GCP-native solution when possible. How should you deploy this service in GCP?

1. A. Create a managed instance group from one of the images of the on-premises servers, and link this instance group to a target pool behind your load balancer.
2. B. Create a target pool, add all backend instances to this target pool, and deploy the target pool behind your load balancer. — đáp án hiện tại
