Where are lakehouse Delta tables stored?

• A. On OneLake storage
• B. In a separate cloud provider's storage
• C. In local on-premises storage only
• D. In memory

Answer: (A)

Delta tables for a lakehouse are stored in OneLake storage, Microsoft Fabric’s unified data lake. The actual data files and the Delta transaction log reside in OneLake, giving a durable, centrally managed storage layer that Fabric compute engines access. They aren’t kept in memory, on-premises only, or in a separate cloud provider’s storage—the OneLake storage location is the single home for lakehouse data across Fabric workloads.
