DP-600 Maintain a Data Analytics Solution Practice Question
You are maintaining a data analytics solution that requires Row-Level Security (RLS) on a semantic model. You need to ensure that the RLS rules continue to function correctly even when the model is switched to Direct Lake mode. What is a key requirement for maintaining RLS in this scenario?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The RLS roles must be defined in the semantic model using DAX filter expressions.
Maintaining security in Direct Lake mode requires careful consideration of how RLS is applied. Because Direct Lake bypasses the SQL endpoint and reads Parquet files directly, RLS must be defined within the semantic model itself. Understanding these requirements ensures that sensitive data remains protected regardless of the storage mode or the performance optimizations being applied to the data solution.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
RLS must be configured at the Lakehouse level using SQL Views instead of in the model.
Why it's wrong here
Configuring RLS only at the Lakehouse level via SQL views will cause the semantic model to fall back to DirectQuery mode. To maintain Direct Lake performance, the security logic must be defined within the semantic model using DAX. Lakehouse-level security is a separate layer that does not automatically propagate to the Direct Lake in-memory engine.
- ✓
The RLS roles must be defined in the semantic model using DAX filter expressions.
Why this is correct
For Direct Lake models, RLS is maintained and enforced by the Power BI engine using DAX. This allows the model to leverage high-performance in-memory processing while still restricting data access based on user identity. It is the standard way to ensure that security is consistent with traditional Import mode models while gaining the benefits of Fabric.
- ✗
Single Sign-On (SSO) must be disabled for the Lakehouse connection to support RLS.
Why it's wrong here
Disabling SSO is not a requirement for RLS and can actually complicate security maintenance by requiring fixed credentials. SSO is often used to ensure that the identity of the user viewing the report is passed through to the underlying data source. RLS in the semantic model functions independently of whether SSO is enabled for the connection.
- ✗
The semantic model must be moved to a Pro capacity to support Direct Lake RLS.
Why it's wrong here
Direct Lake mode is a feature specifically for Fabric (F) and Power BI Premium (P) capacities. It is not available on standard Pro capacities. Therefore, moving the model to a Pro capacity would not only fail to support Direct Lake RLS but would also make the Direct Lake storage mode itself unavailable for the semantic model.
