An engineer must create multiple host projects across folders and share subnets with service projects. To allow them to complete this with the fewest steps, which IAM role and scope do you grant?

Granting the Compute Shared VPC Admin role at the organization level provides the necessary permissions to manage Shared VPC configurations across all projects and folders within the organization. This includes enabling Shared VPC, attaching service projects, and managing host projects. This single grant minimizes steps by centralizing control. Granting at the folder level would require multiple grants if host projects are in different folders. Adding Project IAM Admin is unnecessary as Compute Shared VPC Admin already includes permissions to manage Shared VPC-related IAM policies.
