Microsoft Power BI Data Analyst Practice Question

The correct answer is 'Change detection'. This type of automatic page refresh is designed for this exact scenario. It uses a specific DAX measure to poll the DirectQuery source at a set interval. The full page of visuals will only refresh if the value of that measure has changed, indicating new data has arrived. This is more efficient than a 'Fixed interval' refresh, which would query all visuals on the page at every interval, regardless of whether the data has changed. 'Scheduled refresh' applies to the entire dataset (typically for Import mode) and does not provide real-time page updates. 'Enable personalized visuals' is an unrelated feature that allows end-users to change the visuals they see on a report.
