Implementing Analytics Solutions Using Microsoft Fabric — Question 26

You have a Fabric tenant that contains 30 CSV files in OneLake. The files are updated daily.
You create a Microsoft Power BI semantic model named Model1 that uses the CSV files as a data source. You configure incremental refresh for Model1 and publish the model to a Premium capacity in the Fabric tenant.
When you initiate a refresh of Model1, the refresh fails after running out of resources.
What is a possible cause of the failure?

Answer options

• A. Query folding is occurring.
• B. Only refresh complete days is selected.
• C. XMLA Endpoint is set to Read Only.
• D. Query folding is NOT occurring.
• E. The delta type of the column used to partition the data has changed.

Correct answer: D

Explanation

The correct answer is D because if query folding is not occurring, the entire data is processed instead of being optimized, which can lead to resource exhaustion during refresh. The other options either imply correct configurations or are not directly related to the resource issue during the refresh process.
