You have a deployment of System Center Configuration Manager (Current Branch).
Your company has a main office and a branch office. The branch office has five users. Some users use laptops and some use desktop computers.
All the servers for the company are located in the main office. The branch office connects to the main office by using a VPN over a DSL connection to the main office.
You need to minimize the bandwidth used to deploy updates to branch office clients over the VPN connection. The solution must minimize costs.
A. a pull-distribution point
B. a cloud management gateway
C. BranchCache
D. a cloud-based distribution point
Minimize cost would be branchcache.
All other solutions would mean extra servers or other configurations at the branch office, since there are not servers there.
But yes, its doubt question
Not sure if it is C – there is no information about versions and editions of operating systems on those machines. I would rather go with A.
