If you want your data to automatically refresh as you interact with visualizations in Power BI, which option should you select?

• A. Import
• B. DirectQuery
• C. Live Connection
• D. Dataflow

Answer: (B)

The option that allows your data to automatically refresh as you interact with visualizations in Power BI is DirectQuery. When using DirectQuery, Power BI directly queries the underlying data source in real-time every time you interact with visual elements on your report. This means that if your data changes in the source system, you will see those updates reflected in your reports and dashboards immediately, without needing to perform any manual refreshes. With DirectQuery, the data is not stored within Power BI; instead, queries are sent directly to the data source each time a user interacts with the visualization. This ensures that users are always seeing the most current data available, which is particularly important for scenarios where timely data is critical, such as in operations or monitoring contexts. In contrast, the Import option involves bringing a snapshot of the data into Power BI, which requires manual refreshes to update any changes from the source. A Live Connection also provides real-time updates, but it is specifically designed for connecting to some data sources like SQL Server Analysis Services, which may not be suitable for all scenarios. Dataflow, while useful for data preparation and ETL processes, does not inherently provide real-time interactivity with visualizations like DirectQuery does.
