DP-203 Practice Question: Designing data security for an Azure Data Lake…
You are designing data security for an Azure Data Lake Storage Gen2 account that stores sensitive customer data. You need to ensure that only authorized users can access the data and that access can be audited. Which TWO actions should you implement?
⚠ Common exam trap
A common mix-up: candidates confuse 'allowing access from all Azure services' (Option D) with a secure configuration, but it actually bypasses authentication and auditing, making it a security risk rather than a control.
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
✓
Configure diagnostic settings to send logs to a Log Analytics workspace.
Configuring diagnostic settings to send logs to a Log Analytics workspace enables auditing of data access events, such as read, write, and delete operations, which is essential for compliance and security monitoring. Option E is correct because Azure AD authentication provides fine-grained access control using role-based access control (RBAC) and eliminates the need for shared keys, aligning with the principle of least privilege.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure diagnostic settings to send logs to a Log Analytics workspace.
Why this is correct
Diagnostic settings enable auditing of access.
- ✗
Use storage account access keys (Shared Key) for authentication.
Why it's wrong here
Shared Key does not provide per-user auditing and is less secure.
- ✗
Generate shared access signatures (SAS) with a long expiry time.
Why it's wrong here
Long-lived SAS tokens increase security risk.
- ✗
Configure a firewall to allow access from all Azure services.
Why it's wrong here
Allowing all Azure services may grant unintended access.
- ✓
Enable Azure Active Directory (Azure AD) authentication for the storage account.
Why this is correct
Azure AD provides identity-based access control.
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 |
