As the founder of a stock trading app serving millions, your app communicates with a licensing server at IP 10.194.3.41 to verify its authenticity. You're migrating the server to Compute Engine without changing the app's configuration, ensuring it can still reach the server at the same IP. What's the best approach?
A
Use the IP 10.194.3.41 as a custom ephemeral IP address and assign it to the licensing server.
B
Reserve the IP 10.194.3.41 as a static public IP address using gcloud and assign it to the licensing server.
C
Reserve the IP 10.194.3.41 as a static internal IP address using gcloud and assign it to the licensing server.
D
Use the licensing server with an automatic ephemeral IP address and then promote it to a static internal IP address.
