Option C is interesting, but peering VPCs seems like overkill for a simple web app. Plus, a CNAME record feels a bit outdated. I'd stick with Option B.

Why do we need to create a CNAME record in Cloud DNS? Wouldn't an A record be better since we have a static IP address for the load balancer?

I'm not sure about using Cloud Armor on the load balancer. Isn't that more for security than availability? I'd probably go with Option D instead.

I think Cloud Armor is more for security, not availability.

I think the answer is A because it mentions creating regional network load balancers in each region, which is recommended by Google.
