Which task would be most appropriate for moving data from one server to another in DTS?

The most appropriate task for moving data from one server to another in DTS is the File Transfer Task. This task is specifically designed for transferring files, which can include data files, from one server to another. It effectively manages the movement of files between different locations, making it ideal for scenarios where the intention is to transfer data in file form from one server environment to another.

The other tasks listed have different primary functions. The Data Mapper is used primarily for transforming data between different formats or structures, but it does not directly handle the movement of data between servers. The Bulk Insert Task is geared toward efficiently loading large amounts of data into a database from a file, rather than transferring files or data between servers. The Execute SQL Task is designed to execute SQL statements against a database, which can include queries, updates, and other operations, but it does not facilitate the movement of data files across servers.

In summary, since the File Transfer Task focuses on file-based data movement specifically, it is the most appropriate choice for transferring data between servers in a DTS environment.
