Question 683 of 760
DP-203 Develop data processing Practice Question
You are developing a data processing solution in Azure Synapse Analytics. The solution must use a serverless SQL pool to query Parquet files stored in Azure Data Lake Storage Gen2. Which authentication method should you use to ensure that the queries use the identity of the caller and adhere to Azure role-based access control (RBAC) permissions?
⚠ Common exam trap
A common mix-up: candidates confuse 'service principal' (a fixed identity) with 'user identity' and select option D, not realizing that pass-through authentication is the only method that preserves the caller's individual RBAC permissions.
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
✓
Microsoft Entra ID pass-through authentication.
Microsoft Entra ID pass-through authentication (option A) is correct because it allows the serverless SQL pool to use the caller's identity when accessing Azure Data Lake Storage Gen2. This ensures that Azure RBAC permissions (e.g., Storage Blob Data Reader) assigned to the user are evaluated for each query, providing fine-grained access control without exposing storage account keys or tokens.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Microsoft Entra ID pass-through authentication.
Why this is correct
Microsoft Entra ID pass-through uses the caller's identity and enforces RBAC permissions.
- ✗
Storage account key.
Why it's wrong here
Storage account keys provide full access and do not support granular permissions.
- ✗
Shared access signature (SAS) token.
Why it's wrong here
SAS tokens are static and do not enforce per-user RBAC permissions.
- ✗
Service principal with a secret.
Why it's wrong here
Service principal does not represent the caller's identity.
Quick reference
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 |
