You are managing access to a GCP project. You need to grant 15 developers the ability to view Compute Engine instances. The development team frequently has members joining and leaving.

What is the MOST efficient way to manage their access?

Grant the Compute Viewer role to each developer's individual Google account.

Create a Google Group, add the developers to the group, and grant the Compute Viewer role to the group.

Create a Service Account, grant it the Compute Viewer role, and share the Service Account keys with the developers.

Grant the primitive Viewer role to the entire project for all developers.
