Google Cloud Associate Cloud Engineer — Question 218

You have an on-premises data analytics set of binaries that processes data files in memory for about 45 minutes every midnight. The sizes of those data files range from 1 gigabyte to 16 gigabytes. You want to migrate this application to Google Cloud with minimal effort and cost. What should you do?

Answer options

• A. Create a container for the set of binaries. Use Cloud Scheduler to start a Cloud Run job for the container.
• B. Create a container for the set of binaries. Deploy the container to Google Kubernetes Engine (GKE) and use the Kubernetes scheduler to start the application.
• C. Upload the code to Cloud Functions. Use Cloud Scheduler to start the application.
• D. Lift and shift to a VM on Compute Engine. Use an instance schedule to start and stop the instance.

Correct answer: D

Explanation

The correct answer is D because lifting and shifting to a VM allows you to run the existing binaries with minimal changes, making it the easiest option for migration. Other options like using Cloud Run or GKE would require additional effort for containerization and orchestration, while Cloud Functions is unsuitable for long-running processes like this one.
