Microsoft Fabric Data Engineer Associate DP-700 Practice Question

You manage a Fabric Eventstream that ingests 100,000 telemetry events per second from IoT devices into an Eventhouse table named Telemetry. Analysts complain that KQL queries filtered to the most recent hour take several seconds to return. Investigation shows that ingestion generates thousands of small extents (<50 MB). Without provisioning additional capacity, which configuration change is most likely to improve both ingestion efficiency and query performance?

  • Reduce the table data retention period from 30 days to 7 days.

  • Enable delta ingestion mode on the Eventstream output to the Telemetry table.

  • Increase the target extent size by editing the ingestion batching policy for the Telemetry table.

  • Create a materialized view that summarizes the Telemetry table every five minutes.
