An architect receives a business requirement from a CTO that states the RTO and RPO for a new system should be as close as possible to zero. Which replication method and data center technology…

The correct answer is C. synchronous replication over dual data centers via Metro Ethernet. Metro Ethernet is a high-speed, low-latency network technology that enables synchronous replication between data centers that are relatively close geographically, minimising the impact of latency on system performance and helping to maintain a low RTO.
