Which function do application controls perform as transactions pass through the system?

• A. Prevent, detect, and correct errors and irregularities
• B. Log all transactions for audit
• C. Schedule backups
• D. Approve budgets automatically

Answer: (A)

Application controls built into the software that processes transactions are designed to protect data as it flows through the system by ensuring accuracy, validity, and completeness. As a transaction passes through, these controls prevent bad data from entering (for example, through input validation that checks required fields, formats, and permissible values), detect problems that arise during processing (such as mismatches or calculation errors using checks, reconciliations, or batch totals), and prompt correction or remediation when issues are found (through error handling and exception workflows). This combination—preventing errors, catching them when they occur, and enabling fixes—directly supports reliable and trustworthy transaction processing, which is why it is the best description of what application controls do. Logging all transactions for audit is useful for traceability but is not the core function of processing controls. Scheduling backups relates to data availability and recovery rather than the integrity of each transaction as it moves through the system. Automatically approving budgets is not a typical function of application controls in the processing path.
