Which of the following is the MOST appropriate testing approach when auditing a daily data flow between two systems via an automated interface to confirm that it is complete and accurate?
To confirm that the daily data flow between two systems via an automated interface is complete and accurate, the most appropriate testing approach is to perform data reconciliation for a representative sample, such as 25 days. This method allows for a comprehensive assessment by comparing data in both systems over a period, ensuring consistency and identifying any discrepancies that may indicate issues with data integrity or completeness. This approach directly addresses the requirement of completeness and accuracy in the data flow.
Data reconciliation involves comparing data from one system with data from another system to ensure consistency and accuracy. By performing data reconciliation for a sample of 25 days, auditors can verify the completeness and accuracy of the daily data flow between the two systems over a representative period. This approach provides a comprehensive assessment of the automated interface's performance and allows auditors to identify any discrepancies or anomalies that may indicate issues with data integrity or completeness. Additionally, it offers insights into the reliability of the automated data transfer process and helps ensure that the systems are functioning as intended.
Question asks to confirm that data flow is "complete". This means full data must be examined. "Example output" would not be enough.
I think that option B (Inspect interface configurations and an example output of the systems.) is the correct answer. It directly addresses the completeness and accuracy of the data flow between the systems.
D is right.
