Does a live connection store data within Power BI?

Does a live connection store data within Power BI?

• A. Yes, it stores the data locally
• B. No, it does not store data
• C. Yes, but only for temporary periods
• D. No, only for certain datasets

Answer: (B)

When working with a live connection in Power BI, the data is not stored within Power BI itself. Instead, a live connection allows Power BI to query the data source in real-time, retrieving data directly from the source whenever a report is accessed or interacted with. This means that users are always looking at the most up-to-date information as it reflects the current state of the data source without any local replication. In this context, it’s important to understand that while Power BI offers various data connection modes (such as Import mode, where data is stored locally within the Power BI file), a live connection is specifically designed to enable direct queries to sources like SQL Server Analysis Services (SSAS) or other compatible sources. This design is beneficial for scenarios where data freshness is critical, as it reduces the need for data refresh operations. The other options propose scenarios that misrepresent how live connections function, suggesting that data might be temporarily stored or selectively stored, which is not the case for live connections in Power BI.
