Which of the following options allows for a better management of user access in Power BI?

Row-Level Security is the correct choice for better management of user access in Power BI because it enables granular control over data visibility on a per-user basis. This means that different users can see different data when they view the same report or dashboard, based on predefined security rules. For example, a sales manager can access sales figures for their region, while another user might only see figures for their specific location. This helps ensure that sensitive data is protected and that users only access the information relevant to their role.

In contrast, other options like Column-Level Security provide a percentage of data protection but do not offer the same depth of customization as Row-Level Security. Dashboard Sharing and Report Subscription are more about sharing content and delivering reports, rather than controlling user access based on data confidentiality. Therefore, Row-Level Security stands out as the most effective option for managing user access in a secure and controlled manner.
