Your company operates nationally and plans to use GCP for multiple batch workloads, including some that are not time-critical. You also need to use GCP services that are HIPAA-certified and manage service costs. How should you design to meet Google best practices?

The correct answer leverages preemptible VMs for cost savings on non-time-critical batch workloads, which is a Google best practice for such use cases. It also correctly emphasizes disabling and then discontinuing non-HIPAA-compliant services. Simply discontinuing without disabling first might leave resources active and incurring costs. Standard VMs are more expensive and not ideal for cost-sensitive, fault-tolerant batch jobs. Placing VMs in the same region is a good practice for latency and data locality but doesn't directly address the cost-saving potential of preemptible VMs or the HIPAA compliance requirement as effectively as the correct option.
