- A
Grant the Microsoft Entra ID group the Storage Blob Data Reader role on the storage account
Why wrong: This grants storage access but does not control SQL pool access.
- B
Grant the Microsoft Entra ID group CONNECT permission on the serverless SQL pool and configure ACLs on the storage to allow read access for the group
Both SQL permissions and storage ACLs are needed.
- C
Configure a firewall rule to allow only the Microsoft Entra ID group IP ranges
Why wrong: Firewall rules control network access, not user identity.
- D
Use a shared access signature (SAS) token with the SQL pool and distribute it to users
Why wrong: SAS tokens are not user-specific and are less secure.

DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 have an Azure Synapse Analytics serverless SQL pool that queries data in Azure Data Lake Storage Gen2. You need to ensure that only users with specific Microsoft Entra ID groups can access the data through the serverless SQL pool. What should you configure?
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
✓
Grant the Microsoft Entra ID group CONNECT permission on the serverless SQL pool and configure ACLs on the storage to allow read access for the group
Controlling access involves two layers: the serverless SQL pool and the underlying storage. Users must have both CONNECT permission on the SQL pool to query and appropriate ACLs on the storage to read the data. Granting the Microsoft Entra ID group CONNECT permission and configuring ACLs on the storage account to allow read access for the group ensures that only those users can access data through the serverless SQL pool. Option A is incorrect because the Storage Blob Data Reader role alone does not grant SQL-level permissions. Option C is incorrect because firewall rules are network-level and do not provide granular user access. Option D is incorrect because SAS tokens are not recommended for user-level access and bypass Entra ID permissions.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Grant the Microsoft Entra ID group the Storage Blob Data Reader role on the storage account
Why it's wrong here
This grants storage access but does not control SQL pool access.
- ✓
Grant the Microsoft Entra ID group CONNECT permission on the serverless SQL pool and configure ACLs on the storage to allow read access for the group
Why this is correct
Both SQL permissions and storage ACLs are needed.
Related concept
Standard ACLs match source addresses.
- ✗
Configure a firewall rule to allow only the Microsoft Entra ID group IP ranges
Why it's wrong here
Firewall rules control network access, not user identity.
- ✗
Use a shared access signature (SAS) token with the SQL pool and distribute it to users
Why it's wrong here
SAS tokens are not user-specific and are less secure.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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.

What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related DP-203 ACL questions on filtering logic and placement.
