DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
You are designing a data processing solution in Azure Databricks that uses Unity Catalog. The security team requires that all users authenticate using Microsoft Entra ID and that access to tables is governed by attribute-based access control (ABAC) using table tags. Which feature should you enable?
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
✓
Table tags with access control lists (ACLs) in Unity Catalog. [CORRECT]
In Unity Catalog, attribute-based access control (ABAC) is implemented through table tags combined with access control lists (ACLs). Table tags allow data to be classified, and ACLs can then be configured based on those tags to enforce attribute-based access. This directly satisfies the requirement of using table tags for ABAC. Option B (dynamic views with user context functions) can provide similar controls but does not inherently leverage table tags and is not the dedicated ABAC feature in Unity Catalog.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Column-level security masks. [wrong]
Why it's wrong here
Column-level security masks are used to mask sensitive data at the column level, not for ABAC with tags.
- ✗
Dynamic views with user context functions. [wrong]
Why it's wrong here
Dynamic views with user context functions enable ABAC by filtering data based on the user's attributes, such as group membership or identity, which can be mapped to table tags.
- ✗
Row-level security filters. [wrong]
Why it's wrong here
Row-level security filters restrict rows based on conditions, but they do not directly provide ABAC using table tags in Unity Catalog.
- ✓
Table tags with access control lists (ACLs) in Unity Catalog. [CORRECT]
Why this is correct
Table tags with ACLs in Unity Catalog provide role-based access control (RBAC), not attribute-based access control (ABAC). ABAC requires dynamic views with user context functions.

Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
