To verify that the correct version of a data file was used for a production run, an IS auditor should
review:

A.
operator problem reports.

B.
operator work schedules.

C.
system logs.

D.
output distribution reports.

Explanation:
System logs are automated reports which identify most of the activities performed on the computer.
Programs that analyze the system log have been developed to report on specifically defined items.
The auditor can then carry out tests to ensure that the correct file version was used for a production
run. Operator problem reports are used by operators to log computer operation problems. Operator
work schedules are maintained to assist in human resources planning. Output distribution reports
identify all application reports generated and their distribution.
