ASSOCIATE-CLOUD-ENGINEER practice question 14 of 35

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?

Answer options

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. Correct answer

Correct Answer:

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.

Explanation

The location of a Google App Engine application is a permanent setting chosen during its initial creation within a Google Cloud project. This location cannot be changed after the application is created. Furthermore, a single Google Cloud project can contain only one App Engine application. Therefore, to deploy the application in a new region (asia-northeast1), you must create an entirely new Google Cloud project. Within this new project, you can then create a new App Engine application and specify asia-northeast1 as its serving location during the setup process.

Why Incorrect

A. The project's default region setting primarily affects services like Compute Engine and does not alter the immutable location of an existing App Engine application.
B. The region of an App Engine application is an immutable property. It is set once at creation and cannot be modified later.
C. A Google Cloud project is limited to a single App Engine application. It is not possible to create a second one within the same project.
