Explanation:
Scenario: Data and SourcesData 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 Scenario: Data and Sources

Question 3
You have the following three versions of an Azure SQL database:
- Test
- Production
- Development
You have a dataset that uses the development database as a data source.
You need to configure the dataset so that you can easily change the data source between the development, test, and production database servers from powerbi.com.
Which should you do?
- Create a JSON file that contains the database server names. Import the JSON file to the dataset.
- Create a parameter and update the queries to use the parameter.
- Create a query for each database server and hide the development tables.
- Set the data source privacy level to Organizational and use the ReplaceValue Power Query M function.
Correct answer: D
Explanation:
With privacy level settings, you can specify an isolation level that defines the degree that one data source must be isolated from other data sources.An Organizational data source limits the visibility of a data source to a trusted group of people. An Organizational data source is isolated from all Public data sources, but is visible to other Organizational data sources.Reference:https://docs.microsoft.com/en-us/power-bi/admin/desktop-privacy-levels With privacy level settings, you can specify an isolation level that defines the degree that one data source must be isolated from other data sources.
