Microsoft Fabric Data Engineer Associate DP-700 Practice Question

A Dataflow Gen2 in Microsoft Fabric ingests daily CSV exports from a supplier into a lakehouse and performs several Power Query transformations. Last night the supplier renamed the source column ProductKey to ProductID. The next scheduled refresh failed with the message: "Expression.Error: The column 'ProductKey' of the table wasn't found." You must restore successful refresh as quickly as possible while keeping all downstream transformation logic unchanged. What should you do?

  • Delete and recreate the dataflow using the updated source schema, then re-publish all dependent reports.

  • Drop the destination lakehouse table so the dataflow can create it again during the next refresh.

  • Insert a Power Query step that renames the ProductID column back to ProductKey before the existing steps run, then refresh the dataflow.

  • Edit each subsequent transformation step to reference ProductID instead of ProductKey, then refresh the dataflow.
