Your company’s 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.
Explanation:
BranchCache is designed to reduce WAN link utilization and improve application responsiveness for branch
office workers who access content from servers in remote locations.
Branch office client computers use a locally maintained cache of data to reduce traffic over a WAN link. The
cache can be distributed across client computers (Distributed Cache mode) or can be hosted on a serverin the
branch (Hosted Cache mode).
Distributed Cache mode
If client computers are configured to use Distributed Cache mode, the cached content is distributed among
client computers on the branch office network. No infrastructure or services are required in the branch office
beyond client computers running Windows 7.
Hosted Cache mode
In hosted cache mode, cached content is maintained on a computer running Windows Server 2008 R2 on the
branch office network.
