What should you do to write the results of a Stream Analytics query to a table in Power BI?

To write the results of a Stream Analytics query to a table in Power BI, creating only the workspace is sufficient because Power BI is designed to be user-friendly, enabling users to interact with their data easily. When you configure an output in Stream Analytics to send data to Power BI, the necessary components—namely the dataset and table—are created automatically within the specified workspace.

This automatic creation occurs because Stream Analytics integrates directly with Power BI, understanding the structure needed for reporting. This integration allows for a seamless flow of data and simplifies the process for users, who may not have extensive experience in manually setting up datasets or tables.

In contrast, options that suggest creating both a dataset and table beforehand are unnecessary since Power BI's automatic functions take care of that once the workspace is established. Additionally, attempting to create outputs without the workspace would not be viable, as the workspace provides the needed context and environment for organizing and managing the data outputs.
