Microsoft Fabric Data Engineer Associate DP-700 Practice Question

You manage a Microsoft Fabric lakehouse that receives continuous IoT telemetry. The streaming job appends thousands of small Parquet files to a Delta table named SensorEvents every hour. Data analysts report that interactive queries against SensorEvents have become significantly slower over time. You must improve query performance without changing the existing ingestion process or creating a duplicate copy of the data. Which action should you perform on the table?

  • Execute an OPTIMIZE operation on SensorEvents to compact small files into larger files.

  • Run ANALYZE TABLE SensorEvents COMPUTE STATISTICS to refresh query optimizer statistics.

  • Export SensorEvents to a new table partitioned by ingestion hour and point reports to the new table.

  • Create row-level indexes on the most frequently filtered columns in SensorEvents.
