Question #: 50

Your end users are located in close proximity to us-east1 and europe-west1. Their workloads need to communicate with each other. You want to minimize cost and increase network efficiency.

How should you design this topology?

Show Suggested Answer Hide Answer
Suggested Answer: D

https://cloud.google.com/vpc/docs/using-vpc#create-auto-network

We create one VPC network in auto mode that creates one subnet in each Google Cloud region automatically. So, region us-east1 and europe-west1 are in the same network and they can communicate using their internal IP address even though they are in different Regions. They take advantage of Google's global fiber network.

A VPN setup in A could add unnecessary complexity.

Wait, can we really use just one VPC for both regions? Sounds risky.

Using private IPs in D is definitely the way to go!

I disagree, I think C with a global load balancer is better for scalability.

I’m leaning towards option B, but using external IPs seems risky for security. I need to think more about the implications of that choice.

I feel like option C could work too, but I'm uncertain about the global load balancer aspect. Is it really necessary for this scenario?

I remember practicing a similar question where using private IPs was emphasized for cost efficiency. Maybe option D is the way to go?

I think option A might be a good choice since it uses VPN gateways, but I'm not sure if that's the most cost-effective solution.

This looks like a tricky one. I'll need to carefully read through the requirements and think about the different workflow configuration options.

I'm a bit confused on this one. Let me think through the MLAG setup process again to determine the correct answer.

I remember something about Layer 3 mode handling packets, but I can't recall if it processes or drops them in this case.
