GCP Associate Cloud Engineer Practice Question

Your Shared VPC contains a bastion host whose VM service account is [email protected]. Backend instances that must be reached only through this bastion are labeled with the network tag internal-app. You need a single firewall configuration that permits SSH traffic from the bastion to the back-end VMs and blocks SSH from every other source. Which approach satisfies the requirement while minimizing ongoing administration effort?

  • Create an ingress rule that allows tcp:22 from the VPC's entire RFC 1918 range and targets the internal-app tag.

  • Add an egress rule on the bastion host that allows tcp:22 to the internal-app tag; rely on the default ingress rules for the rest.

  • Create one ingress firewall rule that allows tcp:22 with the bastion service account as the source and the target network tag internal-app.

  • Assign the network tag bastion to the bastion host and create an ingress rule that allows tcp:22 from the bastion tag to the internal-app tag.
