C. Online access controls
D. Before and after image reporting
Answers
Answer: B

A reasonableness check is a data validation edit and control, used to ensure that data conforms to predetermined criteria. Before and after image reporting is a control over data files that makes it possible to trace changes. Online access controls are designed to prevent unauthorized access to the system and data. A hash total is a total of any numeric data field or series of data elements in a data file. This total is checked against a control total of the same field or fields to ensure completeness of processing.   Your Comment
