Synchronous replication, you say? I hope the CTO has deep pockets, because that's going to cost them an arm and a leg. But hey, at least they'll have the data to reattach those limbs!

I heard the CTO wants the RTO and RPO to be as close to zero as possible. That's like asking for a unicorn to deliver the data via telepathy. Good luck with that!

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.
