Hi SherriLynn,
The statement in the course is correct, as far as it goes. When using a linked table in Access 2007, you can make changes to the data without changing the linked file. However, when the linked file is changed, any conflicting changes made in Access will be overwritten. For more information on linked tables, please see http://office.microsoft.com/en-us/access/HP010950951033.aspx.
Hope this resolves your query.
