Domain 3.1: Deploying and implementing Compute Engine resources — GCP ACE Practice Question 21

How to approach this question

Understand how metadata-based SSH keys work in GCP (public key on server, formatted with username).

Full Answer

Format the public key with the contractor's username., Add the public key to the instance metadata of 'db-admin-vm'.

To grant SSH access via metadata (without OS Login), you must format the public SSH key to include the username. Then, you add this formatted public key to the instance-level metadata of the specific VM. The GCP guest environment agent will read this metadata and provision the local user account and authorized_keys file on the VM.

Common mistakes

Selecting project-level metadata, which would grant access to all VMs in the project.
