DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
Your organization uses Azure Data Lake Storage Gen2 to store parquet files. You need to secure the data at rest and control access. Which THREE methods 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
✓
Set POSIX-like ACLs on directories and files.
Options A, B, and D are correct. Encryption at rest is done by Azure Storage Service Encryption. Access control is via RBAC and ACLs. Option C is wrong because firewall restricts network access, not data at rest. Option E is wrong because soft delete is for data recovery, not security.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set POSIX-like ACLs on directories and files.
Why this is correct
ACLs provide fine-grained access control.
- ✓
Configure RBAC roles to control access to storage accounts.
Why this is correct
RBAC provides coarse-grained access control.
- ✗
Configure Azure Storage Firewall to allow only trusted IPs.
Why it's wrong here
Firewall controls network access, not data encryption.
- ✓
Enable Azure Storage Service Encryption (SSE) for data at rest.
Why this is correct
SSE encrypts data at rest by default.
- ✗
Enable soft delete for blobs.
Why it's wrong here
Soft delete is for recovery, not security.
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
1 more way 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. Which TWO security features should be implemented to protect data in Azure Data Lake Storage Gen2?
medium- ✓ A.Role-based access control (RBAC)
- B.Azure Policy
- C.Azure Active Directory (Microsoft Entra ID) integration
- ✓ D.Firewall and virtual network rules
- E.Azure Monitor alerts
Why A: (RBAC) is correct because it provides coarse-grained access control for Azure Data Lake Storage Gen2. Option D (Firewall and virtual network rules) is correct because it restricts network access to the storage account. Option B (Azure Policy) is incorrect because it is used for governance and compliance, not directly for data protection. Option C (Azure Active Directory integration) is incorrect because while it provides authentication, it is not a security feature specific to data protection in ADLS Gen2; it is a prerequisite for RBAC. Option E (Azure Monitor alerts) is incorrect because it is for monitoring and alerting, not for implementing security controls.
