Google Cloud Professional Cloud Developer — Question 209

You are in the final stage of migrating an on-premises data center to Google Cloud. You are quickly approaching your deadline, and discover that a web API is running on a server slated for decommissioning. You need to recommend a solution to modernize this API while migrating to Google Cloud. The modernized web API must meet the following requirements:

• Autoscales during high traffic periods at the end of each month
• Written in Python 3.x
• Developers must be able to rapidly deploy new versions in response to frequent code changes

You want to minimize cost, effort, and operational overhead of this migration. What should you do?

Answer options

• A. Modernize and deploy the code on App Engine flexible environment.
• B. Modernize and deploy the code on App Engine standard environment.
• C. Deploy the modernized application to an n1-standard-1 Compute Engine instance.
• D. Ask the development team to re-write the application to run as a Docker container on Google Kubernetes Engine.

Correct answer: B

Explanation

The correct answer is B because the App Engine standard environment supports auto-scaling, is optimized for Python 3.x, and allows for rapid deployment of application updates. Option A, while also a valid choice, incurs higher costs and operational overhead compared to the standard environment. Options C and D do not provide the same level of simplicity and rapid deployment capabilities as App Engine standard environment, making them less suitable for this scenario.
