Implementing Analytics Solutions Using Microsoft Fabric — Question 12

You have a Fabric tenant that contains a warehouse. The warehouse uses row-level security (RLS).
You create a Direct Lake semantic model that uses the Delta tables and RLS of the warehouse.
When users interact with a report built from the model, which mode will be used by the DAX queries?

Answer options

• A. DirectQuery
• B. Dual
• C. Direct Lake
• D. Import

Correct answer: A

Explanation

The correct answer is A, DirectQuery, because when using row-level security in conjunction with a Direct Lake model, DAX queries must operate in real-time to enforce the security rules. Options B (Dual) and D (Import) do not support the immediate enforcement of RLS, while C (Direct Lake) is the model type, not a query mode.
