A. BITS provides several useful features, particularly the checkpoint-restart capabilities, which apply when an application is configured as download and execute (i.e., the applications files are downloaded to the client before installation). If a client is downloading files from an SMS distribution point and the process is interrupted, the client can continue downloading the files without starting from the first file. If the download is interrupted mid-file and the client reconnects to the same distribution point, the download will continue from the point in the file where the interruption occurred. For example, if the client had downloaded 50MB of a 100MB file when the interruption occurred, the client would reconnect and the download would start from 50MB. If the client connects to a different distribution point, then the download will restart from the beginning of that file
