Question 3

What is the minimum number of Power BI datasets needed to support the reports? 


  1. two importeddatasets 
  2. a single DirectQuerydataset 
  3. two DirectQuerydatasets 
  4. a single importeddataset  
Correct answer: A
Explanation:
Scenario: Data and Sources Data for the reports comes from three sources. Detailed revenue, cost, and expense data comes from an Azure SQL database. Summary balance sheet data comes from Microsoft Dynamics 365 Business Central. The balance sheet data is not related to the profit and loss results, other than they both relate dates.  Monthly revenue and expense projections for the next quarter come from a Microsoft SharePoint Online list. Quarterly projections relate to the profit and loss results by using the following shared dimensions: date, business unit, department, and product category.  Reference: https://docs.microsoft.com/en-us/power-bi/connect-data/service-datasets-understand
