Your companys network includes a main office and several branch offices. The branch offices are connected to the main office by high-latency links. All client computers run Windows 7 Enterprise, and all servers run Windows Server 2008 R2. Servers are located in each of the branch offices. Client computers in the branch offices frequently access a specific group of files on a file server named Server1. These access requests consume significant amounts of bandwidth and reduce the speed of higher-priority traffic. You need to reduce the bandwidth that is consumed by requests for frequently accessed files. What should you do?
A.
Configure BranchCache in Hosted Cache mode on client computers in the main office and the branch offices.
B.
Configure BranchCache in Distributed Cache mode on client computers in the main office and the branch offices.
C.
Enable the BranchCache For Network Files role service on Server1. Configure BranchCache in Distributed Cache mode on a server computer in only the branch offices.
D.
Enable the BranchCache For Network Files role service on Server1. Configure BranchCache in Hosted Cache mode on a server computer in only the branch offices.
If you have a server at a location, use hosted mode. – So shouldn’t the answer be D?

Yes, it should be D not C!

I think it is C, the reason being that Distributed Cache mode at the branch sites actually does reduce the most traffic. There may be a lot of duplication between the file servers, but that’s not part of the question. The question is how do you reduce the most bandwidth, and by setting up two additional DCM servers, there is zero request traffic between the branch and main office, while in an HCM server, you would still be requesting resource pointers, which is still a form of access request, which you’re trying to eliminate.
No one in their right mind would actually setup file distribution this way, but that’s why it’s a Microsoft question.
