What should you do?

You created a Google Cloud Platform project with an App Engine application inside the project. You initially configured the application to be served from the us-central region. Now you want the application to be served from the asia-northeast1 region.

What should you do?
A . Change the default region property setting in the existing GCP project to asia-northeast1.
B . Change the region property setting in the existing App Engine application from us-central to asia-northeast1.
C . Create a second App Engine application in the existing GCP project and specify asia-northeast1 as the region to serve your application.
D . Create a new GCP project and create an App Engine application inside this new project.
Specify asia-northeast1 as the region to serve your application.

Answer: D

Explanation:

https://cloud.google.com/appengine/docs/flexible/managing-projects-apps-billing#:~:text=Each%20Cloud%20project%20can%20contain%20only%20a%20single%20App%20Engine%20application%2C%20and%20once%20created%20you%20cannot%20change%20the%20location%20of%20your%20App%20Engine%20application.

Two App engine can’t be running on the same project: you can check this easy diagram for more info: https://cloud.google.com/appengine/docs/standard/an-overview-of-app-engine#components_of_an_application

And you can’t change location after setting it for your app Engine.

App Engine is regional and you cannot change an apps region after you set it. Therefore, the only way to have an app run in another region is by creating a new project and targeting the app engine to run in the required region (asia-northeast1 in our case).
