Modifying the Developer Settings within PowerBI settings will not prevent User1 from exporting data from visualizations in Contoso Workspace. Developer settings are intended for configuring Apps and APIs, not for managing user permissions related to data export. The correct way to prevent data export would involve adjusting the settings under Export and Sharing in the Admin Portal or modifying the user permissions directly in PowerBI or Office 365 settings.

Based on the information provided, Visual 1 cannot be embedded into a public website due to the use of row-level security (RLS). Visual 3 is excluded because it's from a report shared to your user account, which is not supported for public embedding. Visual 5 is also not supported as it uses a dataset from an on-premises Microsoft SQL Server Analysis Services (SSAS) database. Custom visuals, as indicated by Visual 4, can be embedded, and Visual 2 is stored in Microsoft OneDrive for Business, which is compatible. Therefore, the correct visualizations to embed would be Visuals 2 and 4.
To ensure that users can find data on the dashboard by using natural language queries, you need to enable the Q&A settings specifically for the dashboard. This is done by modifying the Q&A settings from the properties of the dashboard, which will allow users to enter natural language queries directly on the dashboard itself.


To ensure that a sales team can view only data that has a CountryRegionName value of 'United States' and a ProductCategory value of 'Clothing', you should create a new role in Power BI Desktop with the appropriate filters applied to each table. This role should use the filters [CountryRegionName] = 'United States' for the Sales table and [ProductCategory] = 'Clothing' for the Products table. This approach leverages Row-Level Security (RLS), which restricts data visibility at the dataset level based on specific criteria, ensuring that users only see the data relevant to their role.
