Subject Active / Active Data Center and RF

When in active/active data center how to decide right replication factor?
Client may connect and request for the information from either data center
so if locally it's RF=3 then in multiple data center should it be RF=6 in

Or what happens if it's RF=3 with network toplogy and 2 copies are stored in
Site A and 1 copy in Site B data center. Now client for some reason is
directed to Site B data center and does a write, now would Site B have 2
copies and Site A one (or still 2)? It's getting confusing slowly :) I have
several more questions but will start with understanding this first.
