- A
Enable Microsoft Entra ID authentication and grant users permissions via Azure RBAC on the storage account.
Microsoft Entra ID pass-through authentication allows users to authenticate with their Azure AD identities, and RBAC controls access to storage, minimizing overhead.
- B
Use managed identities for the serverless SQL pool.
Why wrong: Managed identities are for Azure resources, not for individual user authentication.
- C
Use storage account access keys for authentication.
Why wrong: Storage account keys grant full access to the storage account and are not identity-based, leading to security risks and high overhead.
- D
Use shared access signatures (SAS) tokens generated for each user.
Why wrong: SAS tokens require token generation and rotation, increasing administrative overhead and not leveraging existing identities.
Azure Synapse Serverless SQL Pool Access Control: Entra ID and Azure RBAC
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Your organization uses Azure Synapse Analytics serverless SQL pools to query data in Azure Data Lake Storage Gen2. You need to ensure that only authorized users can access the data via the serverless SQL endpoint, while minimizing administrative overhead. What should you use?
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
Enable Microsoft Entra ID authentication and grant users permissions via Azure RBAC on the storage account.
Option A is correct because Microsoft Entra ID authentication allows users to authenticate with their existing identities, and Azure RBAC on the storage account provides granular, identity-based access control without managing separate SQL logins or credentials, minimizing administrative overhead. Option B is incorrect because managed identities are designed for service-to-service authentication, not for individual users. Option C is incorrect because storage account access keys provide broad, shared access that does not support per-user identity and auditing. Option D is incorrect because SAS tokens require token generation and management per user, adding overhead.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
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 |

Same concept, more angles
2 more ways this is tested on DP-203
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Your organization uses Azure Synapse Analytics serverless SQL pools to query data in Azure Data Lake Storage Gen2. You need to ensure that only users with specific Microsoft Entra ID roles can query the data. What should you configure?
medium- ✓ A.Assign the Storage Blob Data Contributor role to the users on the Azure Data Lake Storage Gen2 account.
- B.Generate a shared access signature (SAS) token for the storage account and include it in the external table definition.
- C.Configure an IP firewall rule on the storage account to allow only the SQL pool's outbound IP addresses.
- D.Create a managed identity for the SQL pool and grant it access to the storage account.
Why A: Option A is correct because Azure Synapse Analytics serverless SQL pools rely on Microsoft Entra ID tokens and RBAC roles to authorize access to data in Azure Data Lake Storage Gen2. The Storage Blob Data Contributor role grants read and write access to data. Option B is wrong because SAS tokens are shared secrets, not tied to user identity. Option C is wrong because firewall rules control network access, not user-level authorization. Option D is wrong because managed identity is not suitable for per-user authorization.
Variation 2. Your organization uses Azure Synapse Analytics with serverless SQL pools. You need to ensure that only users with specific Microsoft Entra ID roles can query external tables referencing Azure Data Lake Storage Gen2. What should you configure?
medium- A.Assign a managed identity to the serverless SQL pool and grant it Storage Blob Data Reader on the storage account.
- B.Use Azure RBAC to assign Storage Blob Data Reader role to the users on the storage account.
- C.Configure a storage account firewall to allow only the Synapse workspace IP range.
- ✓ D.Grant SELECT permission on the external table to specific Microsoft Entra ID users or groups.
Why D: Option D is correct because granting SELECT permission on the external table directly controls which Microsoft Entra ID users or groups can query the data via the serverless SQL pool. This approach uses Azure AD authentication to restrict access at the query level, not at the storage layer. Option A is incorrect because assigning a managed identity to the serverless pool provides a service identity, but it does not restrict access per user. Option B is incorrect because Azure RBAC on the storage account grants data access at the storage level, not through the Synapse SQL engine, and does not limit querying via external tables. Option C is incorrect because the storage account firewall controls network access, not user identity, and does not prevent authorized users from other networks from querying.
