F5 or Tile cache?
I need help understanding in what scenario it's a page refresh and in what scenario it's only a tile refresh. The answer is D but majority are saying B.
I have tried F5 for a dashboard linked to a report published from PowerBI Desktop, though it is not directly connecting to the SQL data source. It does show the refresh time, and the data changes are reflected.
Can someone make the explanation more comprehensive?

Query caching instructs Power BI Premium or Power BI Embedded capacity to use its local caching service to maintain query results, thereby avoiding the need to have the underlying data source compute those results. Caching is performed the first time a user opens a report. The service performs query caching only for the initial page on which they land. In other words, no queries are cached when you interact with the report. Cached query results are specific to the user and semantic model context and always follow security rules. When Power BI performs a semantic model refresh, the query cache is flushed. When the query cache is flushed, Power BI must run a query against the underlying data model to get the latest results.
Pressing F5 will refresh the entire web page using the browser's cache. This means that it reloads the page and any data already cached in the browser. f5 refresh is limited to the browser and does not update the underlying data model.

It's an imported dataset. The signal for a rerendering of the tiles would have to come from a (successful) refresh of the underlying semantic model. You as the dashboard user have no control over that.
So it should be the tile cache right? Also, pressing F5 would just refresh the page and show: Refresh Now?
No. It's D and E (model refresh completed).
There's no E. This is a PL300 question.
When you said the user have no control over the refresh of an underlying semantic model... how does it do the refresh? Scheduled? Auto?
