A. B. C. D.B.
Of the four options given, the report that would best assist an IS auditor evaluating the effectiveness of preventive maintenance is option D, Activity.
Preventive maintenance is a proactive approach to maintaining IT systems, hardware, and software to minimize downtime, ensure reliability, and extend the life of the systems. To evaluate the effectiveness of preventive maintenance, an IS auditor needs to examine reports that provide information on the activities performed in the preventive maintenance process.
The activity report would provide information on the work performed, such as the types of preventive maintenance activities carried out, their frequency, and the resources used in executing them. This information is critical in assessing the effectiveness of preventive maintenance, as it helps identify if the maintenance activities are aligned with the maintenance plan and if they are being executed adequately.
Downtime and Help desk reports would not provide a comprehensive view of preventive maintenance effectiveness. The downtime report would only provide information on the amount of time the system was unavailable, while the Help desk report would only show issues that users reported. These reports do not provide an insight into the preventive maintenance activities that were conducted to prevent system downtime or issues.
The violation report would only indicate instances of security violations, and while these incidents may be caused by insufficient preventive maintenance, they do not directly provide information on the effectiveness of preventive maintenance.
In summary, the Activity report would provide the best information for an IS auditor to evaluate the effectiveness of preventive maintenance.
