Which of the following describes a root cause analysis?

Root cause analysis focuses on determining the underlying event or condition that triggered the problem, not just addressing its symptoms. Identifying the circumstances that initiated the problem allows IT staff to implement a permanent fix and prevent recurrence rather than repeatedly treating surface-level effects.

Replicating the problem in a test environment is part of the troubleshooting and verification phase, not the definition of root cause analysis itself.

Listing corrective actions describes the remediation phase of problem management, which occurs after the root cause has already been identified.

Confirming the theory of probable cause is a distinct step within structured troubleshooting methodology, not the definition of root cause analysis.
