What does row-level security do in Power BI?

Row-level security in Power BI is a powerful feature that ensures that users can only view the data they are authorized to see, based on their roles. This mechanism allows for personalized data experiences by applying security filters at the data level. When a report is consumed, row-level security checks the user's role and filters the data accordingly, ensuring that sensitive or confidential information is not exposed to unauthorized users.

With row-level security, organizations can set up user roles within their Power BI datasets, defining which data each role can access. This is particularly important in scenarios where multiple departments or user groups share the same report but require access to different subsets of data. By utilizing this feature, organizations can enhance data governance, comply with regulations, and maintain data integrity while still allowing collaborative insights across the organization.

The other options, while related to data management and security, do not accurately describe the primary function of row-level security in Power BI. Row-level security specifically focuses on access constraints based on user roles, distinguishing it clearly from encryption, data backup, or dataset management functions.
