I operate = 5 nodes cluster (3.11.0) in a single data center with SimpleSnitch, = SimpleStrategy and all client policy RoundRobin.

At this point, I am going to create = clusters of the same size in different data centers.

I think these two = documents are appropriate, but there is confusion because they are = referenced to each other.

Anyone who can clearly guide the order? Currently RF is = 2 and I want to have only one replica in the = NetworkTopologyStrategy.
A little data loss is = okay.

Thank = you in advanced..
