Microsoft Fabric Data Engineer Associate DP-700 Practice Question

You run analytics queries against a Delta table stored in a Microsoft Fabric lakehouse. After weeks of streaming upserts, you discover the table path now contains thousands of small Parquet files, and scan latency has noticeably increased when filtering on the OrderDate column. You need to consolidate the files and improve data-skipping without rewriting the ingestion pipeline. Which action should you take?

  • Enable Change Data Feed (CDF) on the table to reduce query latency.

  • Run VACUUM on the table with a zero-hour retention period to delete all old files.

  • Create a clustered columnstore index on the table to accelerate scans on OrderDate.

  • Execute an OPTIMIZE statement on the table with a ZORDER BY (OrderDate) clause to compact and co-locate data.
