Which tool is MOST effective for monitoring transactions that exceed predetermined thresholds?

Generalized audit software is the most effective tool for monitoring transactions that exceed predetermined thresholds because it is specifically designed to analyze large volumes of data and detect anomalies. This type of software can perform detailed audits, allowing auditors to define specific parameters or thresholds for transactions that may be considered unusual or suspicious.

By setting these predetermined thresholds, the software can automate the process of identifying transactions that exceed these limits, enabling more efficient detection of potential fraud or operational issues. This capability is particularly beneficial in environments with large transaction volumes where manual monitoring would be impractical.

On the other hand, integrated test facilities are used for testing system changes within a live environment, regression tests focus on ensuring that new software updates do not negatively affect existing functionalities, and transaction snapshots involve capturing the state of transactions at a moment in time. While these other tools have their respective uses, they are not tailored for ongoing monitoring of transactions against specific thresholds like generalized audit software is.
