Dashboard tile cache frequency has no bearing on gateway data transfer

Short answer

B No, the dashboard tile cache lives in the service and never touches the gateway, so its frequency changes nothing on the wire.

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 decrease the dashboard cache update frequency. Does this meet the goal?
  1. Yes
  2. No Correct Answer

Key Takeaways

Dashboard tile caching happens inside the Power BI service between datasets and dashboard visuals — it neither pulls from on-premises sources nor participates in Import refresh traffic, so its frequency cannot change gateway volume.

In the same gateway scenario, the proposed solution decreases the dashboard cache update frequency to reduce the data sent through the gateway by Import-mode semantic models.

Common mistake: Assuming anything named 'refresh' touches the gateway — the tile cache is a service-side rendering layer fed from the already-loaded dataset, entirely downstream of the on-premises connection.

Expert Analysis

Why the Answer Is Correct

Dashboard tiles are served from a cache that Power BI service updates periodically by querying the underlying (already imported) dataset — a process wholly inside the cloud service. The on-premises data gateway is only exercised during dataset refresh or live DirectQuery connections. Changing how often tile caches update therefore alters service-internal query load against the dataset, but the amount of data crossing the gateway during Import refreshes remains exactly the same. The solution does not meet the goal.

Why the Other Options Are Wrong

Answering Yes would require the tile cache pipeline to reach back through the gateway to the on-premises source, which it does not: tiles read from the imported dataset, not the source. Even reducing cache updates only changes how often the service reads from its own dataset — no bytes on the on-premises-to-cloud path are saved either way.

Community Comment Notes

A commenter notes that adjusting dashboard cache frequency does not directly reduce data sent through the gateway by Import-mode semantic models, matching the documented separation between tile caching and gateway refresh. The Yes camp's reasoning asserts a gateway connection during cache updates that does not exist.

    Chat GPT: The dashboard cache update frequency determines how often Power BI refreshes the dashboard visuals from the dataset. Adjusting this frequency does not directly reduce the amount of data sent through the on-premises data gateway for semantic models in Import storage mode.

    Decreasing the dashboard cache update frequency might not directly reduce the amount of data sent through the gateway by semantic models in Import storage mode.

    The answer is A-YES because: To reduce the amount of data sent through the gateway by semantic models in Import storage mode, decreasing the dashboard cache update frequency is a valid solution because it means the gateway will need to fetch updated data from the source less often, minimizing the data transfer volume.
