CompTIA Data+ DA0-002 (V2) Practice Question

A data analyst is reviewing a quarterly sales dashboard and notices that the total revenue for the 'East' region is 50% lower than the previous quarter, which is highly unusual. Stakeholders have confirmed this does not align with their operational activities. The dashboard's data is sourced from a production sales database. The analyst suspects an issue with the data being pulled for the report. What is the most effective initial step to validate the integrity of the source data?

  • Review the dashboard's interactive filters to ensure the analyst has not accidentally excluded a key product category.

  • Submit the dashboard's underlying code and calculations for a peer review to identify logical errors.

  • Run a separate, simple query directly against the production sales database to sum the revenue for the 'East' region and compare it to the dashboard's figure.

  • Check the report server's monitoring alerts to determine if a slow refresh rate is causing stale data to be displayed.
