Question

You have a data processing pipeline that uses Cloud Dataproc to load data into BigQuery. A team of analysts works with the data using a Business Intelligence (BI) tool running on Windows Virtual Machines (VMs) in Compute Engine. The BI tool is in use 24 hours a day, 7 days a week, and will be used increasingly over the coming years. The BI tool communicates to BigQuery only. Cloud Dataproc nodes are the main part of the GCP cost of this application. You want to reduce the cost without affecting the performance. What should you do?

Explanation

A is correct. This will ensure that the BI Tool is as cheap as possible on Compute Engine, and the ephemeral usage of Cloud Dataproc will also reduce costs. B is incorrect. The Committed Use Discount for the Cloud Dataproc nodes will result in a recurring charge, even when the cluster has been deleted. C is incorrect. This will not be enough. Further cost reduction can be achieved. D is incorrect. This will not be enough. Further cost reduction can be achieved. https://cloud.google.com/compute/docs/instances/signing-up-committed-use-discounts
