Correct answer & explanation
✓
MySQL database (on-premises)
Power BI Desktop provides native connectors for a wide range of data sources, including many on-premises databases. Both MySQL and Oracle databases have dedicated native connectors that allow direct connection from Power BI Desktop without requiring a gateway. This is a common point of confusion because the Power BI Service requires a gateway for on-premises data, but Desktop connections are direct.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap is that candidates often think native connectors are only available for cloud-based or Microsoft-specific services, but Power BI Desktop includes native connectors for many popular on-premises databases like MySQL and Oracle.
Detailed technical explanation
How to think about this question
Native connectors in Power BI Desktop are built using the Power Query M language and directly integrate with cloud services like Azure Blob Storage and Dataverse via REST APIs or OData endpoints, bypassing the need for on-premises data gateways. For Azure Blob Storage, the connector supports anonymous, account key, and SAS token authentication, and can handle large datasets by partitioning blob reads. Dataverse uses the OData v4 protocol, enabling real-time querying of tables and views with support for incremental refresh.
KKey Concepts to Remember

- Power BI Desktop Direct Connection
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
Native Connector
Real-world example
How this comes up in practice
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.
