Turn Off Configured Services in GCP Project: Best Practices

C.

The answer to this question is A: "Verify that you are assigned the Project Owners IAM role for this project. Locate the project in the GCP console, click Shut down and then enter the project ID."

Explanation:

To reduce the GCP service costs for a division of your company, you need to turn off all configured services in an existing GCP project. The following steps can be taken to achieve this:

1. Verify that you are assigned the Project Owners IAM role for this project: In order to modify project settings and shut down a project, you must have the appropriate IAM role assigned to your user account. In this case, you need to have the Project Owners IAM role in the project to shut down the configured services.

2. Locate the project in the GCP console and shut it down: In the GCP console, search for the project ID or navigate to it in the Project selector drop-down menu. Then, click on the "Project info" button located at the top of the console. From here, click on the "Shut down" button and enter the project ID to confirm the shutdown.

Note that shutting down a project in GCP will disable all resources associated with the project, including Compute Engine instances, Cloud Storage buckets, Cloud SQL databases, etc. It is important to ensure that you have backed up any necessary data before shutting down the project. Additionally, the shutdown process cannot be undone, so be certain that this is the desired action before proceeding.

Option B is incorrect because deleting resources individually can be time-consuming, and it may not be immediately clear which resources are configured for the project.

Option C and D are also incorrect because the Organizational Administrator IAM role is not required to shut down a GCP project. The Project Owners IAM role provides sufficient permissions to shut down the project.
