A company has a requirement of an active/active datacenter and wants to implement synchronous replication for all its storage services. The company is doing a proof of concept with a datacenter provider that has two datacenters 200mi (322km) apart that utilize MPLS. Each time the company starts synchronous replication, it fails. All network connectivity has been established and is functioning correctly. Which of the following is the MOST likely cause?
A) Latency between datacenters
B) Applications are latency tolerant
C) Link bandwidth between datacenters
D) Link between datacenters is not fiber

Latency between datacenters is the most likely cause of synchronous replication failure. Synchronous replication requires that data be written to both datacenters at the same time, and latency can cause data to be written to one datacenter before the other, resulting in a failure.
