Question 431 of 966
Which Data Sources Support DirectQuery in Power BI?
This PL-300 practice question tests your understanding of prepare the data. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which TWO of the following are valid data source types in Power BI that support DirectQuery? (Select TWO.)

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Snowflake
Snowflake is a cloud-based data warehouse that supports DirectQuery in Power BI, allowing queries to be sent directly to Snowflake without importing data into Power BI's in-memory engine. This is possible because Snowflake provides a SQL-based interface that Power BI can connect to via its native connector, enabling real-time querying of large datasets.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse file-based or list-based data sources (like Excel, JSON, or SharePoint) as being DirectQuery-capable because they can be connected to Power BI, but DirectQuery is strictly limited to relational databases and data warehouses that support live query execution.
Detailed technical explanation
How to think about this question
DirectQuery in Power BI translates report visuals into native SQL queries sent to the source database, bypassing the VertiPaq in-memory engine. For Snowflake and Azure Synapse Analytics, this leverages their MPP (Massively Parallel Processing) architectures to handle large-scale queries efficiently, but it also imposes limitations such as no support for time intelligence functions and slower performance compared to Import mode due to network latency and query execution overhead.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which TWO data sources can be used with DirectQuery mode in Power BI? (Choose two.)
easy- A.Excel workbook
- ✓ B.SQL Server
- ✓ C.Azure SQL Database
- D.CSV file
- E.SharePoint list
Why B: SQL Server is correct because it is a relational database that supports DirectQuery mode in Power BI, allowing queries to be sent directly to the source without importing data. This enables real-time access to large datasets while leveraging SQL Server's query processing capabilities.
