- A
Enable Azure Storage Service Encryption (SSE) for data at rest
SSE encrypts all data at rest automatically.
- B
Enable diagnostic settings to audit access
Why wrong: Auditing logs access, does not encrypt data.
- C
Configure firewall rules to restrict network access
Why wrong: Firewall rules secure data in transit/network, not at rest.
- D
Enable soft delete for blobs
Why wrong: Soft delete protects against accidental deletion, not encryption.
- E
Use Azure RBAC to grant least privilege access to storage accounts
RBAC controls access, a key security principle.

How to Secure Data at Rest in Azure Data Lake Storage Using SSE and 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.

Correct answer & explanation
✓
Enable Azure Storage Service Encryption (SSE) for data at rest
To secure data at rest in Azure Data Lake Storage Gen2, enable Azure Storage Service Encryption (SSE) for automatic encryption of stored data, and use Azure RBAC to enforce least privilege access to the storage account. SSE protects data at rest at the storage layer, while RBAC controls who can access the data, preventing unauthorized access. Option B (diagnostic settings) is for auditing, not encryption. Option C (firewall rules) is network-level security. Option D (soft delete) is for recovery, not data-at-rest protection. Thus, the correct answers are A and E.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Why this is correct
RBAC controls access, a key security principle.
Related concept
Authentication checks who the user is.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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 |
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related DP-203 questions on access control and AAA configuration.

Same concept, more angles
1 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. Which TWO actions should you take to secure data at rest in Azure Data Lake Storage Gen2? (Choose TWO)
medium- ✓ A.Use Azure RBAC to grant least-privilege access to the storage account.
- B.Apply dynamic data masking to sensitive columns.
- ✓ C.Enable Azure Storage Service Encryption (SSE) for data at rest.
- D.Configure firewall rules to restrict network access.
- E.Enable audit logging for the storage account.
Why A: Correct answers: A and C. A: Use Azure RBAC to grant least-privilege access to the storage account—this ensures only authorized users can access data. C: Enable Azure Storage Service Encryption (SSE) for data at rest—this encrypts data automatically at the storage level. B is incorrect because dynamic data masking is used for databases, not for Azure Data Lake Storage Gen2. D is incorrect because firewall rules control network access, not data at rest. E is incorrect because audit logging is for monitoring, not securing data at rest.
