Microsoft Fabric Data Engineer Associate DP-700 Practice Question
You manage a Microsoft Fabric workspace that includes a Lakehouse for enterprise reporting. IoT devices publish JSON-encoded telemetry to an Azure Event Hubs namespace at about 5,000 events per second. You need a streaming ingestion pattern that
lands raw events in near real time to a Bronze Delta table in the Lakehouse,
automatically adapts to evolving JSON schemas without manual column mapping, and
guarantees at-least-once delivery even after service restarts. Which Fabric component should you use?
Ingest the data into a Real-Time Analytics KQL database and configure continuous export to a Lakehouse Delta table.
Enable mirroring on the Event Hubs namespace and surface the mirrored data as a Lakehouse table.
Create an Eventstream that reads from the Event Hubs namespace and writes directly to a Delta table in the Lakehouse.
Build a Fabric pipeline with a Copy activity that polls Event Hubs every minute and writes to the Lakehouse.
Ingesting events from Azure Event Hubs into a Real-Time Analytics KQL database and enabling continuous export to a Lakehouse Delta table meets all requirements. Real-Time Analytics provides durable, at-least-once ingestion and stores data in OneLake. When continuous export to a Lakehouse table is enabled, the system automatically keeps the Delta table's schema in sync with the KQL table, so new JSON fields are added without manual intervention. Eventstream and pipeline Copy activities require manual schema updates for Delta sinks, while mirroring is not intended for Event Hubs ingestion.
