Option A sounds like a solid choice to me. Asynchronous replication over dual data centers via DWDM is the way to go. It's fast, reliable, and you can't beat that dual data center setup. Plus, the name 'DWDM' just sounds cool, doesn't it?

I'm all about that low latency life, so I'm going with option C - synchronous replication over dual data centers via Metro Ethernet. It may not be as geographically dispersed, but the speed and reliability will be top-notch.

Hold on, aren't we forgetting the cost factor here? Synchronous replication can be pretty pricey. I'm leaning towards option D - asynchronous replication over geographically dispersed dual data centers via CWDM. It may not be as fast, but it's more budget-friendly.

Wow, an RTO and RPO close to zero? That's a tall order! I'd say option B - synchronous replication over geographically dispersed dual data centers via MPLS is the way to go. It's the most robust solution to ensure minimal data loss and downtime.

But MPLS provides better reliability and lower latency, which is important for achieving zero RTO and RPO.
