Exam CISA topic 1 question 505 discussion

C is the most critical because it proves the spreadsheet’s results are correct

reconciliation - supports data accuracy and completeness

While reviewing the formulas within macros (option B) is also important for understanding the logic and functionality of the macros, it may not provide a complete assessment of the accuracy of the spreadsheet's calculations. Reconciliation of key calculations offers a more comprehensive approach by validating the outputs produced by the macros against independent calculations or external data sources. Therefore, it is the MOST important aspect for an IS auditor to review when evaluating the accuracy of a spreadsheet containing macros.

An IS auditor should carefully review the logic and functionality of the macros, focusing on the formulas used within them The Answer B

MOST important aspect for an IS auditor to review is: C. Reconciliation of key calculations. While all options are relevant to assessing the accuracy and reliability of the spreadsheet, reconciliation of key calculations is crucial because it ensures that the results produced by the macros align with the expected outcomes. Reviewing the reconciliation process helps verify the integrity of the data and the correctness of the calculations performed by the macros.

For accuracy, use formula. Answer is B. For Completeness, use Reconciliation

When evaluating the accuracy of a spreadsheet that contains several macros, both the version history and reconciliation of key calculations are important. However, the **reconciliation of key calculations** is generally considered **more crucial**. This is because it directly verifies the accuracy of the calculations performed by the macros. While version history can provide information about the changes made to the spreadsheet over time, it does not necessarily ensure the accuracy of the current calculations. Therefore, an IS auditor should prioritize reviewing the reconciliation of key calculations.

B. Formulas within macros. The Question is about Accuracy and not completeness. Reconciliation would be done to verify the completeness rather than accuracy.

why not B?

C. Reconciliation of key calculations
