Question

You recently deployed Compute Engine instances in regions us-west1 and us-east1 in a Virtual Private Cloud (VPC) with default routing configurations. Your company security policy mandates that virtual machines (VMs) must not have public IP addresses attached to them. You need to allow your instances to fetch updates from the internet while preventing external access. What should you do?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Create a Cloud NAT gateway and Cloud Router in both us-west1 and us-east1. Cloud NAT lets private instances reach the internet for outbound traffic without external IPs.
