The Marketing Department for CSM Tech Publishing is busy producing videos and print materials (stored in PDF format) for distribution and use by the Sales Department. With new products being introduced and a good bit of marketing testing, marketing materials change often, and there's often a substantial delay before the Sales Department gets access to these changes. The Sales Department is in another site and wants access to the marketing materials, but given the size of files and the number of updates, you're reluctant to give the Sales Department direct access to files across the WAN link. What DFS replication group configuration could you consider for replication and frequency of access?
