During troubleshooting, which outcomes are supported by data collection?

• A. Baselines
• B. Trend analysis
• C. Verification of root cause and effectiveness of fix
• D. All of the above

Answer: (D)

Data collection during troubleshooting provides concrete evidence you can rely on to anchor decisions, monitor changes, and confirm improvements.

Baselines come from recording normal operating metrics so you have a reference point to compare against when issues occur. This helps you recognize when something is off and quantify the deviation.

Trend analysis comes from gathering data over time. It reveals patterns, directions, or cycles in performance, letting you see whether problems are developing, persisting, or resolving, and it informs preventative actions.

Verification of root cause and effectiveness of the fix comes from post-change data. After implementing a solution, continued measurements show whether the issue has truly been resolved and whether the fix had the intended impact without introducing new problems.

Because data collection supports establishing baselines, enabling trend analysis, and validating the fix, all of these outcomes are supported.
