What is a possible cause of the failure?

You have a Fabric tenant that contains 30 CSV files in OneLake. The files are updated daily.

You create a Microsoft Power Bl semantic model named Modell that uses the CSV files as a data source. You configure incremental refresh for Model 1 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?
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 data type of the column used to partition the data has changed.

Answer: E

Explanation:

A possible cause for the failure is that query folding is NOT occurring (D). Query folding helps optimize refresh by pushing down the query logic to the source system, reducing the amount of data processed and transferred, hence conserving resources.
