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.
