A VM in project corp-iot-insights generates daily reports. Team in project corp-aggregate-reports needs a copy in bucket corp-aggregate-reports-storage. Use minimum steps and Google-recommended practices. What should you do?

Granting the VM's service account the Storage Object Creator role on the corp-aggregate-reports-storage bucket is the most secure and efficient method. This follows the principle of least privilege, giving the VM only the necessary permissions to write to the target bucket without over-provisioning access. Moving projects under the same folder is unnecessary for this task and doesn't directly address the permission requirement. Creating a Shared VPC is for network connectivity, not for granting Cloud Storage object creation permissions. Making the bucket public is a significant security risk and should be avoided, especially for sensitive data.
