Microsoft Fabric Data Engineer Associate DP-700 Practice Question

You manage a lakehouse in Microsoft Fabric. The Delta table named Sales is appended to every few minutes, creating thousands of small data files. Business analysts report that queries which filter on the ProductCategory column are increasingly slow. You must improve scan performance and reduce file fragmentation without changing the ingestion pipeline design. Which action should you perform?

  • Export the Sales table to a single compressed CSV file and query that file instead of the Delta table.

  • Run VACUUM Sales RETAIN 0 HOURS to delete obsolete small files.

  • Run the command OPTIMIZE Sales ZORDER BY (ProductCategory) from a Fabric notebook.

  • Create a columnstore index on the ProductCategory column.
