You're migrating an on-premises application to Google Cloud. The application uses a component that requires a licensing server. The license server has the IP address 10.28.0.10. You want to deploy the application without making any changes to the code or configuration. How should you go about deploying the application?

A. Create a subnet with a CIDR range of 10.28.0.0/28. Reserve a static internal IP address of 10.28.0.10. Assign the static address to the license server instance. B. Create a subnet with a CIDR range of 10.28.0.0/28. Reserve a static external IP address of 10.28.0.10. Assign the static address to the license server instance. C. Create a subnet with a CIDR range of 10.28.0.0/28. Reserve an ephemeral internal IP address of 10.28.0.10. Assign the static address to the license server instance. D. Create a subnet with a CIDR range of 10.28.0.0/28. Reserve an ephemeral external IP address of 10.28.0.10. Assign the static address to the license server instance.
