To minimize service costs with the fewest steps, you need to turn off all configured services in an existing GCP project. What should you do?

To turn off all services and minimize costs in a GCP project, shutting down the project is the most efficient method. This action stops all billing and deletes all resources within the project. The Project Owner IAM role is required to perform this operation. You can initiate the shutdown process from the Cloud Console by navigating to the project settings, selecting "Shut down," and confirming with the project ID. The other options are incorrect because: Deleting resources individually is more time-consuming and prone to missing services, potentially incurring ongoing costs. The Organization Administrator role is not necessary for shutting down a single project; the Project Owner role is sufficient and adheres to the principle of least privilege.
