You are the company administrator. The company plans to open a new branch office. The new branch office will operate using a 56 Kbps connection to the main office until high-speed internet can be installed in about three months. A server will be deployed to the new office that will function as an RODC, file server, and infrastructure server. Users at the new branch office will frequently need to access policy files located on servers at the main office. These policy files are created and maintained by users at the main office. Company regulations prohibit policy files from being permanently stored in any location other than on the file servers in the main office. You need to recommend a solution for users in the new branch office to optimize access to files in the main office. What should you include in the recommendation?
