- A
Use Azure RBAC with Microsoft Entra ID and enable diagnostic settings for Azure Storage
Azure RBAC with Microsoft Entra ID provides fine-grained access control to Azure Data Lake Storage Gen2, ensuring only authorized users can access data. Diagnostic settings capture read, write, and delete operations for auditing. This combination meets both authorization and auditing requirements.
- B
Use Azure managed identities to access the storage account
Why wrong: Managed identities provide authentication for Azure services, not user-level authorization or auditing. They do not meet the requirement for controlling which users can access data or for auditing user actions.
- C
Use shared access signatures (SAS) with stored access policies
Why wrong: Shared access signatures (SAS) with stored access policies grant time-limited access but do not provide per-user auditing or fine-grained RBAC. They are typically used for delegated access, not for user authorization and auditing.
- D
Configure the storage account firewall to allow only Azure Databricks IP addresses
Why wrong: Storage account firewall restricts network access, but does not control which users can access data or provide audit logs of user operations. It is not sufficient for the stated requirements.
DP-203 Design and implement data storage Practice Question
This DP-203 practice question tests your understanding of design and implement data storage. 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 team uses Azure Databricks to process data stored in Azure Data Lake Storage Gen2. You need to ensure that only authorized users can access the data and that access is audited. What should you implement?
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
Use Azure RBAC with Microsoft Entra ID and enable diagnostic settings for Azure Storage
Azure RBAC with Microsoft Entra ID (formerly Azure AD) provides fine-grained access control to Azure Data Lake Storage Gen2, ensuring only authorized users can access data. Enabling diagnostic settings for Azure Storage captures read, write, and delete operations, which are sent to a Log Analytics workspace, storage account, or event hub for auditing. This combination meets both the authorization and auditing requirements specified in the question. Option A is correct.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Managed identities provide authentication for Azure services, not user-level authorization or auditing. They do not meet the requirement for controlling which users can access data or for auditing user actions.
- ✗
Use shared access signatures (SAS) with stored access policies
Why it's wrong here

Why it's wrong here
Storage account firewall restricts network access, but does not control which users can access data or provide audit logs of user operations. It is not sufficient for the stated requirements.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse authentication (managed identities) with authorization and auditing, or they assume network-level controls (firewall) are sufficient for access control and auditing, when in fact Azure RBAC with diagnostic settings is required for user-level authorization and audit trails.
Detailed technical explanation
How to think about this question
Azure RBAC for Data Lake Storage Gen2 uses the `Storage Blob Data Owner`, `Storage Blob Data Contributor`, and `Storage Blob Data Reader` roles, which are mapped to POSIX-style ACLs at the file and directory level. Diagnostic settings capture storage logs in the `StorageRead`, `StorageWrite`, and `StorageDelete` categories, which include the OAuth authentication details (e.g., user principal name) when using Microsoft Entra ID. In a real-world scenario, a data engineer might use Azure RBAC to grant a team member read-only access to a specific container while enabling diagnostic logs to track which files were accessed and by whom, satisfying compliance requirements like GDPR or SOC 2.
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.
TExam Day Tips
- 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 |
