Question

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You have an on-premises data gateway. You need to reduce the amount of data sent through the gateway by semantic models that run in Import storage mode. Solution: You create aggregations to summarize results. Does this meet the goal?

Why each option

Creating aggregations to summarize results effectively reduces the amount of data sent through an on-premises data gateway for Power BI semantic models in Import storage mode.

AYesCorrect

Aggregations summarize detailed data into a smaller, pre-calculated dataset, meaning only this reduced dataset needs to be fetched from the on-premises source through the data gateway for Import mode semantic models. This significantly lowers the volume of data transferred, meeting the goal of reducing gateway traffic.
