What does Row-Level Security (RLS) do in Power BI?

Row-Level Security (RLS) in Power BI is a feature that allows for the implementation of security measures at the row level in datasets. This means that RLS is specifically designed to restrict data access for individual users based on certain conditions or filters applied to the data. For instance, an organization may want to ensure that sales representatives can only view data pertinent to their own territories or product lines. By defining RLS rules, administrators can control what data specific users or groups can see, enhancing data privacy and compliance with data governance policies.

The other options are not aligned with the purpose of RLS. Generating summary reports pertains to data aggregation and visualization rather than user-specific access, modifying layout of visuals is related to design and presentation aspects of reports, and turning off data alerts temporarily concerns notifications rather than data accessibility.
