ExpertGCP PCA · Question 33 · Cost Optimization
A startup is running a stateless web application on Compute Engine. The traffic is highly unpredictable, with sudden spikes and long periods of low usage. They want to minimize compute costs but cannot commit to a 1-year or 3-year contract because their architecture might change next month. Which cost optimization strategy is most appropriate?

Answer options:
Purchase 1-year Committed Use Discounts (CUDs) for the peak capacity.
Use a Managed Instance Group with autoscaling enabled, and rely on Sustained Use Discounts (SUDs) for the baseline instances.
Run the entire application on Preemptible/Spot VMs.
Provision the maximum required instances statically to ensure performance, and use Custom Machine Types to save money.
