Quick Answer
The correct answer is SQL Server row-level security with the USER_NAME() function because this approach directly filters data at the database level by matching the current user’s identity to region-specific rows in the SQL Server table. When Power Apps passes the authenticated user context, SQL Server’s security predicate evaluates the USER_NAME() function to restrict which records each user can view or update, ensuring that a sales rep from the West region only sees West-region customers. On the PL-900 exam, this question tests your understanding of where data security boundaries lie—many candidates mistakenly choose Dataverse security roles, but those only apply to Dataverse tables, not SQL Server. A common trap is confusing app-level permissions (Power Apps security groups) with row-level data filtering, which must happen in the database itself. Remember the memory tip: “SQL filters rows by user; Dataverse roles by table; app groups by access.”
This PL-900 practice question tests your understanding of demonstrate the capabilities of power apps. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You need to design a Power App that allows users to view and update customer records from a SQL Server database. The app must enforce row-level security based on the user's region. What should you use?
Power Apps security groups
Why wrong: Controls access to the app, not data within the app.
Dataverse security roles
Why wrong: Only applies to Dataverse tables, not SQL Server.
Environment security
Why wrong: Controls access to the environment, not row-level data.
SQL Server row-level security with the USER_NAME() function
SQL Server RLS filters rows based on the user executing the query.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
SQL Server row-level security with the USER_NAME() function
Option A is correct because row-level security can be implemented in SQL Server by filtering data based on user context passed from Power Apps. Option B is wrong because security roles in Dataverse are for Dataverse tables, not SQL Server. Option C is wrong because Power Apps security groups control app access, not data filtering. Option D is wrong because environment security restricts environment access, not row-level data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Power Apps security groups
Why it's wrong here
Controls access to the app, not data within the app.
Dataverse security roles
Why it's wrong here
Only applies to Dataverse tables, not SQL Server.
Environment security
Why it's wrong here
Controls access to the environment, not row-level data.
SQL Server row-level security with the USER_NAME() function
Why this is correct
SQL Server RLS filters rows based on the user executing the query.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
