GCP Associate Cloud Engineer Practice Question

Your company runs a regional managed instance group with virtual machines in zones us-central1-a and us-central1-b. For security, the VMs are created without external IP addresses, yet they must regularly retrieve operating-system updates from public repositories on the internet. Management wants a solution that provides high availability across zones while keeping operational effort to a minimum. Which approach should you take?

  • Reserve a regional external IPv4 address for every VM and attach it as a secondary interface so the instances can reach the internet directly.

  • Deploy two Cloud NAT gateways, one in each zone, use manual NAT IP allocation, and add custom routes so each VM uses the gateway in its own zone.

  • Launch a pair of third-party VM-based NAT appliances behind an internal load balancer and configure the VMs to forward all outbound traffic through the appliances.

  • Create a single regional Cloud NAT gateway on a Cloud Router in us-central1 and let it automatically allocate external IP addresses.
