Microsoft Power BI Data Analyst Practice Question

A Power BI Desktop model currently imports 120 million detailed transaction rows from Azure SQL Database. Report visuals summarize revenue at day level and never expose individual transactions. To decrease in-memory model size and accelerate DAX queries while keeping calculation results unchanged, which action should you take before the data is loaded into the model?

  • Change the table's storage mode from Import to DirectQuery.

  • Enable column profiling and column quality options in Power Query.

  • Use Power Query Group By to pre-aggregate the transactions to one row per day before loading.

  • Set all relationships that involve the transaction table to single cross-filter direction.
