The Administering Windows Server Hybrid Core Infrastru cture materials explain that BranchCache reduces WAN utilization by caching content that clients request from a remote content server. There are two modes : Hosted Cache and Distributed Cache . Hosted Cache “requires a server in the branch office configured as a hosted cache server,” while Distributed Cache “uses a peer-to-peer cache among Windows clients and does not require any servers in the branch .” For SMB shares, the content server (the file server at the main site) must have the “BranchCache for Networ k Files” role service installed so that it can advertise hashes and support BranchCache for file content. Client computers in the branch are then configured to Enable BranchCache in Distributed Cache mode so they can cache and retrieve content from each ot her, minimizing repeated downloads across the WAN.

In this scenario, Montreal has no servers , so Hosted Cache is not suitable. Installing BranchCache for Network Files on Server1 (the Boston file server hosting \\Server1\Apps ) and enabling Distributed Cach e on the 20 Windows 10 clients in Montreal meets the requirement to reduce WAN saturation during the LOB app deployment and subsequent updates while requiring no additional branch infrastructure .
