Which statement describes the Fabric lakehouse architecture?

• A. A pure relational database engine.
• B. A hierarchical folder structure only.
• C. It combines file storage flexibility of a data lake with SQL-based query capabilities of a data warehouse.
• D. It is a real-time messaging system.

Answer: (C)

The idea being tested is that a lakehouse blends the flexibility of a data lake with the query power of a data warehouse. In Fabric, data lives in a data-lake-style storage of files, while a metadata layer, governance, and optimized query engines enable fast SQL queries, ACID transactions, and structured analytics on that data. This lets you run BI and SQL workloads over both structured and semi-structured data without moving it into a separate warehouse.

This isn’t just a pure relational database engine, and it isn’t merely a hierarchical folder structure. It provides SQL access directly over lake-stored data with warehouse-like capabilities. It also isn’t a real-time messaging system.
