CompTIA Data+ DA0-002 (V2) Practice Question

After today's automated refresh, a retail sales dashboard suddenly shows a Gross Profit Margin of 215 %, yet a manual SQL check of the ERP system still returns the expected 20 % range. No ETL errors were logged and other visuals appear normal. Before involving the data-engineering team, which review technique should the analyst apply first to efficiently locate the problem inside the report?

  • Examine the report's measures and aggregation formulas to verify that the profit-margin calculation logic is correct.

  • Perform a detailed line-by-line code review of the overnight ETL and SQL extraction scripts that populate the model.

  • Ask a colleague to conduct a peer review focused on the dashboard's visual design and storytelling elements.

  • Configure an automated alert that emails the analyst whenever the profit-margin card exceeds a predefined threshold.
