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.
