Microsoft Power BI Data Analyst Practice Question

You are a data analyst managing a Power BI report. Users have reported that a specific matrix visual, which contains several DAX measures, is rendering very slowly. You need to determine which specific DAX query associated with the visual is the primary cause of the slow performance. What is the most effective initial step to take within Power BI Desktop to diagnose this issue?

  • Use the Performance Analyzer pane to record the visual's rendering and inspect the 'DAX query' duration.

  • In the Model view, review all relationships and ensure the cross-filter direction is set to 'Single'.

  • Reduce the number of rows in the source tables by applying filters in the Power Query Editor.

  • Connect to the data model using DAX Studio and enable Server Timings to trace all queries.
