You have three users who travel to four branch offices often and need to log on to the RODCs at these offices. The branch offices are connected to the main office with slow WAN links. You don't want domain controllers at the main office to authenticate these three users when they log on at the branch offices. What should you do that requires the least administrative effort yet adheres to best practices?

Why were most movies from the late 1890s until the early 1930s only filmed in black and white? there were only a few people who could afford the technology to produce color motion pictures back then. audiences did not want color motion pictures until later. the film used to make color motion pictures often overheated, which was a safety hazard, so it was generally not allowed. color films had to be hand-colored, frame by frame.
