It should be dataset, because the case states there is already a report published and the datamodel contains measures. therefore and to be able to use the measures in the datamodel you should connect to the existing dataset (which was created when you plublished the report) instead of starting from scratch with the files in the SharePoint folder.

Dataset has been renamed to semantic model, so PBI dataset should be equivalent to PBI Semantic model. https://learn.microsoft.com/en-us/power-bi/connect-data/service-datasets-rename Back to the question, for the purpose of minimizing development effort, by using an existing semantic model may save time from clear, transform and load the data source.

After reading the question multiple times, the biggest takeaway is that its asking directly for data. A SharePoint folder HOLDS data, but it is not data itself. I agree with this and think its the existing dataset

The question is confusing because it doesn't tell clearly that there are two reports. So the second report can reuse the dataset of the first one.

I think the question is clear: Publish the first report, and then create the second report from dataset of the first report

The question also implies that there is a report already created, so using the PBI dataset will include the calculated metrics

The correct answer should be Dataset. A connection with the Share folder was initiated for the first report. After publishing the report a Power BI dataset was created and by connecting with it we minimize the development.

Agree with Nomios! Answer I am going with: Existing Dataset bc the qs clearly states that the report is already published and the data model of that published report contains measures. Therefore, to be able to use those measures in the already published dataset, use: Existing dataset)

The question is: "Which type of data source should you use?" The Power BI dataset is NOT a data source. https://learn.microsoft.com/en-us/power-bi/connect-data/desktop-data-sources Thus, since it should have minimal developing impact, it should be answer B "Sharepoint folder".
