CompTIA Data+ DA0-002 (V2) Practice Question

A cloud retailer relies on a BI dashboard fed by an hourly incremental ETL job from the transactional system. During a walk-through you notice that the dashboard's revenue totals have been identical for the past three hours, yet the ETL job status page shows the most recent run succeeded. As the analyst assigned to validate the report, which action will best determine whether stale data in the underlying dataset is the root cause?

  • Recalculate the revenue KPI using a different aggregation method to rule out formula errors.

  • Reduce the dashboard's auto-refresh interval from 15 to 5 minutes in the BI tool settings.

  • Clear the browser cache and reload the dashboard to eliminate client-side caching.

  • Query the warehouse table that feeds the dashboard and compare its row count and latest updated_at timestamp with the corresponding source table.
