Answer: Reserve a static internal IP address of 10.28.0.10 within a subnet that has a CIDR range of 10.28.0.0/28, and assign this static address to the license server instance.
The correct answer is **A** because the IP address in question is internal and can be reserved using a static internal IP address. This action prevents the address from being allocated to other resources. Static internal IPs allow you to reserve addresses from the private RFC 1918 IP range configured in the subnet, ensuring that the same IP address can be used for the same resource even after deletion and recreation. Options **B** and **D** are incorrect as the IP address must be internal, not external. Option **C** is incorrect because ephemeral internal IP addresses are released back into the network pool when the VM instance is stopped and restarted or terminated, which does not meet the requirement for a persistent IP address.

You are migrating an on-premises application to Google Cloud. This application includes a component that requires a licensing server with the IP address 10.28.0.10. Your goal is to deploy the application without altering its code or configuration. What is the best approach to deploy the application under these conditions?
A
Reserve a static internal IP address of 10.28.0.10 within a subnet that has a CIDR range of 10.28.0.0/28, and assign this static address to the license server instance.
B
Reserve a static external IP address of 10.28.0.10 within a subnet that has a CIDR range of 10.28.0.0/28, and assign this static address to the license server instance.
C
Reserve an ephemeral internal IP address of 10.28.0.10 within a subnet that has a CIDR range of 10.28.0.0/28, and assign this static address to the license server instance.
D
Reserve an ephemeral external IP address of 10.28.0.10 within a subnet that has a CIDR range of 10.28.0.0/28, and assign this static address to the license server instance.
