Q: 15
You decide to set up Cloud NAT. After completing the configuration, you find that one of your instances is not using the Cloud NAT for outbound NAT. What is the most likely cause of this problem?

B . If you assign an external IP to the instance, it won't use Cloud NAT for egress.
Had something like this in a mock. B is correct since if the VM has its own external IP, it bypasses Cloud NAT and sends outbound traffic directly.
Don’t think it’s A, since extra interfaces wouldn’t force direct outbound traffic. B is the catch-external IP lets the instance skip Cloud NAT. Seen this tripping people up before on similar practice tests.
