A company using Microsoft Fabric wants its warehouses, lakehouses, and reports to read the same underlying files without copying data between silos. Which component provides that shared storage layer?
Show answer and explanation
Answer: D
OneLake is the single logical data lake that underpins every Microsoft Fabric workload. Lakehouses, warehouses, and other items store their data there, so different experiences can read the same files without duplicating them. It is built on Azure Data Lake Storage Gen2 technology. Premium capacity supplies compute, Event Hubs ingests event streams, and notebook runtimes execute code rather than storing data.
Why the other options are wrong
- A. A Power BI Premium capacity supplies compute and feature licensing for reports and models. It does not provide the shared file storage layer.
- B. Azure Event Hubs ingests high-volume event streams. It is a messaging service and not a shared storage layer for Fabric items.
- C. Notebook runtimes execute Spark or Python code against data. They consume storage but do not provide it.
Exam tip. One copy of data shared across Fabric workloads is OneLake.
