Which of the following is an example of proactive problem management?

Automated detection of faults via event or alert tools is a function of event management and incident detection, not an activity of problem management.

When a technical support group analyzes an incident and reveals an underlying problem, this represents proactive problem management - the team is not merely closing the incident but investigating the root cause to prevent future occurrences. This technical-level investigation, initiated by the support group rather than by the service desk reacting to a report, is the defining characteristic of the proactive approach.

Detection or suspicion of a cause by the service desk is reactive problem management, as it is directly triggered by an incoming incident report rather than independent technical investigation.

Trending of historical incident records is an analytical technique used within problem management but describes a statistical review activity rather than the active technical investigation that characterizes proactive problem management.
