In Fabric, what concept allows referencing schema without binding to a specific provider until read time?

• A. Early binding schema.
• B. Late-bound schema.
• C. Hardened schema.
• D. Static schema.

Answer: (B)

Late-bound schema means you reference the data’s structure without fixing it to a specific provider or storage format upfront. The schema is declared in your query or semantic model, but the actual binding to a data source happens only at read time. When you read, the Fabric runtime resolves the real data source and applies the schema on the fly, returning data in the expected shape.

This approach offers flexibility across heterogeneous sources and supports schema evolution because the binding occurs when data is read, not when you define the schema. It’s different from tying the schema to a particular provider at design time, which reduces adaptability and cross-source querying.
