GCP Associate Cloud Engineer Practice Question

Your security team wants to replace instance-level SSH keys with an IAM-based mechanism on all new Compute Engine VMs. Linux administrators must still be able to run sudo after logging in. You need to implement this with the fewest possible steps before the next VM is created. What should you do?

  • Create a startup script that writes each administrator's public key to /home/$/.ssh/authorized_keys on every VM.

  • Enable IAP for TCP forwarding on the project and grant the administrators group roles/iap.tunnelResourceAccessor.

  • Add the metadata key enable-oslogin=TRUE at the project level and grant the administrators group the IAM role roles/compute.osAdminLogin.

  • Add the metadata key block-project-ssh-keys=TRUE at the project level and grant the administrators group roles/compute.instanceAdmin.v1.
