Question 1 of 6

A retail company wants Spark engineers, SQL analysts and Power BI developers to work on the same data without creating duplicate copies. Which architecture best aligns with Microsoft Fabric best practices?

Question 2 of 6

A partner tells a prospect that Copilot in Fabric only becomes available from an F64 capacity onward, based on what applied back during preview. Is that still accurate, and what should the partner actually check now?

Question 3 of 6

After a good demo, an architect wants to bring all of a manufacturer's data sources into Fabric via Mirroring, including the SAP ERP and the EDI and CSV files on SFTP. Why can you not adopt that as-is for either source?

Question 4 of 6

Five multi-tenant customers share a Spark transformation capacity. The team relies on row-level security defined on the SQL analytics endpoint for tenant isolation. Why does that not protect the tenants once an engineer with workspace access works in a notebook?

Question 5 of 6

A Fabric report built on a Direct Lake semantic model suddenly becomes much slower after the underlying Delta tables grow well beyond their original size. What is the most likely explanation?

Question 6 of 6

A team manages Dev, Test and Prod Fabric workspaces connected through Git integration and deployment pipelines. Connection strings and lakehouse IDs differ per environment. What is the recommended way to manage these differences?
