Exam Preparation Quiz

Explanations for each answer:

• Create a transformation dataflow that will apply all the necessary data transformations is incorrect. Transformation dataflows may involve complex processing that increases refresh time and risk of failure, making them unsuitable when source access is limited to a short window.
• Create a linked table that will reference the data from another dataflow is incorrect. A linked table only reuses data already extracted, it doesn’t help with initial extraction from a source with a restricted time window
• Create a shared dataset that can be reused by multiple Power BI reports is incorrect. Shared datasets support reuse at the reporting layer but do not extract or stage source data, and they still require scheduled refresh that may fall outside the limited access window.
• Create a staging dataflow that will only copy the data from the source as-is is correct.
