GCP Associate Cloud Engineer Practice Question

Your company runs dozens of Linux virtual machines on Compute Engine across several projects. Security policy states that:

  • Each SSH key must be linked to an individual Google Cloud IAM identity.
  • VM administrators must never edit instance or project metadata manually to add or remove keys.
  • When an employee's IAM account is disabled, the employee must instantly lose SSH access to every VM.

Which approach satisfies all of these requirements with the least operational overhead?

  • Store each engineer's public key in project-wide metadata under the ssh-keys field and instruct administrators to remove keys when employees leave.

  • Enable OS Login on every project and grant each engineer the IAM role roles/compute.osLogin (or roles/compute.osAdminLogin). Engineers add their own public key to their OS Login profile and connect with gcloud compute ssh.

  • Create a dedicated service account that holds a single SSH key, grant it the compute.instanceAdmin IAM role, and share the key with all engineers.

  • Ask administrators to append each engineer's key directly to /home/username/.ssh/authorized_keys on every VM using a configuration-management script.
