A. B. C. D.A.
When exceptions in the batch mode of an online sales booking system cause some transactions to not get posted, the IS auditor should review the error detection and handling procedures to identify the root cause of the problem and make recommendations for improving the system's resilience. Therefore, the correct answer is A.
Here's why the other options are not as important as A:
B. Changes to the scheduling program: Changes to the scheduling program may be important, but they are unlikely to be the root cause of the problem identified by the IS auditor.
C. The vulnerability of source code and parameters configured: The vulnerability of the source code and parameters configured may be important, but it is unlikely to be the cause of the problem unless there is evidence of a security breach.
D. The nature and frequency of network connection failures: The nature and frequency of network connection failures may be important to identify, but they are unlikely to be the root cause of the problem identified by the IS auditor.
Overall, the IS auditor should focus on reviewing the error detection and handling procedures to identify the root cause of the problem and recommend solutions to prevent future occurrences.
