For a Power BI report showing real-time sales data, which data connectivity mode is most appropriate?

• A. Import Data
• B. DirectQuery
• C. Live Connection
• D. Scheduled Refresh

Answer: (B)

The most appropriate data connectivity mode for a Power BI report showing real-time sales data is DirectQuery. This mode allows Power BI to directly query the underlying data source rather than importing the data into the Power BI model. Since real-time sales data is subject to frequent changes, using DirectQuery ensures that users see the most current data as it is fetched live from the data source each time a report is accessed or interacted with. DirectQuery is particularly beneficial for scenarios where up-to-the-minute data is crucial, such as monitoring sales. It enables reporting on large datasets without the need for data import, ensuring that users are always working with the latest information, which is essential in a dynamic sales environment. In contrast, the Import Data mode involves loading data into Power BI and thus requires a refresh to show updated data, making it unsuitable for real-time reporting needs. Live Connection, while also real-time in nature, is typically used with specific sources like SQL Server Analysis Services and may come with its limitations regarding the transformations and calculations that can be implemented. Scheduled Refresh is focused on periodically updating the imported data but would not provide the real-time insights that DirectQuery allows.
