One way to track activity in a system is a...

• A. GANTT chart
• B. An audit trail
• C. A data backup
• D. Biometrics

Answer: (B)

Tracking system activity relies on recording what happens, when, and by whom. An audit trail is exactly that kind of log: it captures events, the user or process responsible, timestamps, and the data affected. This creates accountability and a traceable history that can be reviewed for troubleshooting, security investigations, and compliance checks. The other options don’t serve this purpose: a GANTT chart outlines planned project tasks and timelines rather than actual system actions; a data backup is a preserved copy of data for recovery, not a record of activity; biometrics is about verifying identity to grant access, not logging what actions were taken. So the best choice for tracking activity is an audit trail.
