Google Cloud Professional Cloud DevOps Engineer — Question 25

You need to run a business-critical workload on a fixed set of Compute Engine instances for several months. The workload is stable with the exact amount of resources allocated to it. You want to lower the costs for this workload without any performance implications. What should you do?

Answer options

• A. Purchase Committed Use Discounts.
• B. Migrate the instances to a Managed Instance Group.
• C. Convert the instances to preemptible virtual machines.
• D. Create an Unmanaged Instance Group for the instances used to run the workload.

Correct answer: A

Explanation

The correct answer is A because Committed Use Discounts provide cost savings for long-term workloads with stable resource needs. Options B and D do not inherently reduce costs, and option C could lead to performance issues due to the temporary nature of preemptible VMs.
