CompTIA Data+ DA0-002 (V2) Practice Question

A scheduled refresh of a Power BI sales dashboard fails with this message:

Expression.Error: The column 'SalesAmount' of the table wasn't found.

The data-warehouse team confirms that the column was recently renamed to Total_Sales in the source view that the dataset imports. To restore the dashboard with the least disruption, which validation action should the analyst take first?

  • Refresh the dataset's schema and remap the missing field to the new Total_Sales column in the data model.

  • Delete and recreate the on-premises data gateway connection for the dataset.

  • Rebuild indexes on the source table to improve query performance.

  • Extend the scheduled refresh time-out so the query has more time to run.
