Answer options:

A.You can use only one dataset for the report
B.You can create a dashboard with one and more pages
C.You can view the dashboard data
D.You can share both a report and a dashboard

Correct Answers: A and D 
You can create reports in both Power BI Service and Power BI Desktop applications. But you can create dashboards in Power BI Service only. A dashboard is a single page that has tiles. Tiles are rectangular areas that contain data visualizations from the reports or the real-time datasets. Dashboards can contain multi-page reports users can access. On the dashboards, you can mix your tiles with the tiles from other dashboards.
Option A is correct because the report’s data source can be only one dataset.
Option D is correct because you can share both a report and a dashboard.
Option B is incorrect because a dashboard has only one page. But a dashboard can include reports with one and more pages.
Option C is incorrect because there is no dashboard data. A report has data. You can view the data of the report that is included in a dashboard.
