Google Cloud Associate Cloud Engineer — Question 222

Your company is running a three-tier web application on virtual machines that use a MySQL database. You need to create an estimated total cost of cloud infrastructure to run this application on Google Cloud instances and Cloud SQL. What should you do?

Answer options

• A. Create a Google spreadsheet with multiple Google Cloud resource combinations. On a separate sheet, import the current Google Cloud prices and use these prices for the calculations within formulas.
• B. Use the Google Cloud Pricing Calculator and select the Cloud Operations template to define your web application with as much detail as possible.
• C. Implement a similar architecture on Google Cloud, and run a reasonable load test on a smaller scale. Check the billing information, and calculate the estimated costs based on the real load your system usually handles.
• D. Use the Google Cloud Pricing Calculator to determine the cost of every Google Cloud resource you expect to use. Use similar size instances for the web server, and use your current on-premises machines as a comparison for Cloud SQL.

Correct answer: D

Explanation

The correct answer is D because it involves directly calculating costs for each Google Cloud resource using the Pricing Calculator, which provides the most accurate estimate. Other options like spreadsheets or load testing may not yield precise cost estimates as they rely on indirect methods or assumptions rather than specific pricing data.
