Which TWO features can be used to secure data in Power BI?
⚠ Common exam trap
Many exam-takers confuse features for data exploration or navigation (Q&A, bookmarks, drill-through) with actual security controls, leading them to select options that enhance user experience rather than protect data.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Row-level security (RLS)
Row-level security (RLS) [CORRECT] is a Power BI security feature that restricts data access for given users by applying DAX filter expressions to roles defined in the dataset, so users only see the rows they are permitted to view. Sensitivity labels [CORRECT] are Microsoft Purview Information Protection labels applied to Power BI items (datasets, reports, dashboards) that classify and protect data, enforcing encryption and access policies even when content is exported to Excel, PowerPoint, or PDF. The other options are not security features: Q&A visuals let users ask natural-language questions of data, Bookmarks capture a saved view state of a report page, and Drill-through navigates to a filtered detail page — all are interactive/reporting capabilities, not data-protection mechanisms.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Q&A visuals
Why it's wrong here
Q&A visuals let users query data using natural language; they apply no permission filtering and can expose values a user should not see. They are tempting because they restrict what is displayed through query phrasing, but they would be correct when building conversational exploration, not for enforcing row-level security.
- ✗
Bookmarks
Why it's wrong here
Bookmarks capture saved filter and visibility states for report navigation; they are cosmetic and bypassable, enforcing no identity-based restriction. They are tempting because they hide visuals from view, but they would be the right choice when guiding report storytelling, not for securing data by role or row.
- ✗
Drill-through
Why it's wrong here
Drill-through navigates from a summary to detail pages; it enforces no row-level or object-level access control. It is tempting because it controls what a report consumer can view, but it would be the right choice when designing interactive report navigation, not for restricting data by user identity or role.
- ✓
Row-level security (RLS)
Why this is correct
Row-level security in Power BI restricts data at query time by evaluating DAX filter expressions against each user's identity, so recipients see only permitted rows. It satisfies the requirement to secure data by enforcing access within a single semantic model, using Microsoft Entra ID or workspace roles to scope visibility.
- ✓
Sensitivity labels
Why this is correct
Sensitivity labels apply Microsoft Purview classification metadata directly to Power BI datasets, reports and dashboards, enforcing encryption and access restrictions even when content is exported to Excel or PDF. This satisfies the stem's requirement to secure data, extending protection beyond workspace permissions to the data itself.
