CompTIA Data+ DA0-002 (V2) Practice Question

After last night's refresh, the ecommerce dashboard is showing every order three times, so the total revenue KPI has tripled. The visualization uses a live connection to the company's Snowflake data warehouse, and the ETL job's execution log reported no errors. No changes were published to the dashboard itself. Which action should the data analyst take first to determine whether the duplication originates in the visualization layer or in the warehouse?

  • Post a question to the BI vendor's community forum to ask about duplicate-row rendering defects.

  • Run a SQL query on the warehouse table to count rows per unique order ID and check for duplicates.

  • Clear the dashboard's cache and republish the workbook.

  • Increase the BI server's memory allocation to handle larger result sets.
