Quick Answer
The answer is DirectQuery mode, because it enables Power BI to query the Azure SQL Database live for each visual, ensuring the dashboard reflects the latest sales data without manual intervention. When combined with the Automatic page refresh setting, DirectQuery sends T-SQL queries to the database on a timer—such as every 10 minutes—making it ideal for near-real-time dashboards. On the Microsoft Azure Data Fundamentals DP-900 exam, this scenario tests your understanding of connectivity modes: Import stores a snapshot and requires scheduled refreshes, while DirectQuery queries the source directly, avoiding storage overhead. A common trap is choosing Import because it’s more familiar, but the requirement for updates every 10 minutes without manual refresh points to DirectQuery’s auto page refresh capability. Memory tip: “DirectQuery = Direct Live Access” — if the data must stay live and refresh automatically, think DirectQuery, not Import.
This DP-900 practice question tests your understanding of describe an analytics workload on azure. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A data analyst needs to create a real-time dashboard in Power BI that displays sales data from an Azure SQL Database. The dashboard must update every 10 minutes without manual refresh. Which Power BI feature should they use?
DirectQuery mode
DirectQuery queries the source directly, enabling near real-time updates.
Scheduled refresh with Import mode
Why wrong: Import mode requires scheduled refresh, not real-time updates.
Streaming datasets
Why wrong: Streaming datasets are for real-time data from sources like Azure Stream Analytics, not SQL Database.
Paginated reports
Why wrong: Paginated reports are for formatted, print-ready reports, not live dashboards.

Correct answer & explanation
DirectQuery mode
DirectQuery mode is correct because it allows Power BI to query the Azure SQL Database directly for each visual interaction, ensuring the dashboard reflects the latest data without requiring a manual refresh. Since the requirement is for updates every 10 minutes, DirectQuery can be configured to auto-refresh at that interval via the 'Automatic page refresh' setting, which sends T-SQL queries to the database on a timer. This avoids the latency and storage overhead of importing data, making it ideal for near-real-time monitoring.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Scheduled refresh with Import mode
Why it's wrong here
Import mode requires scheduled refresh, not real-time updates.
Streaming datasets
Why it's wrong here
Streaming datasets are for real-time data from sources like Azure Stream Analytics, not SQL Database.
Paginated reports
Why it's wrong here
Paginated reports are for formatted, print-ready reports, not live dashboards.
Common exam traps
The trap here is that candidates confuse 'real-time dashboard' with 'streaming datasets' (Option C), but streaming datasets require a push-based architecture, not a pull from an existing database like Azure SQL Database, which DirectQuery handles natively.
Detailed technical explanation
Under the hood, DirectQuery translates Power BI DAX queries into native SQL queries sent to Azure SQL Database via the Tabular Data Stream (TDS) protocol, leveraging the database's query engine for computation. A subtle behavior is that DirectQuery has a default query timeout of 225 seconds and imposes limitations on DAX functions (e.g., no time intelligence), which can impact complex measures. In a real-world scenario, if the database has heavy transactional load, DirectQuery with 10-minute auto-refresh could cause performance degradation, so indexing and query optimization are critical.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
