The correct actions are to enable Azure Storage Service Encryption (SSE) for data at rest and to use Azure RBAC to control access to the storage account. SSE, which is enabled by default in Azure Data Lake Storage Gen2, automatically encrypts all data written to the account using 256-bit AES encryption, ensuring that your data at rest is protected without any additional configuration or performance overhead. Azure RBAC complements this by restricting which users or applications can access the storage account, preventing unauthorized retrieval of encrypted data. On the DP-203 exam, this question tests your understanding that encryption at rest is a built-in, default feature of Azure Storage, not an optional add-on, and that access control via RBAC is a separate but equally critical security layer. A common trap is confusing data masking or firewall rules with encryption—remember, encryption scrambles the data itself, while firewalls control network traffic. Memory tip: SSE is always on, so focus on RBAC for the second action.
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. 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.
Which TWO actions should you take to secure data at rest in Azure Data Lake Storage Gen2? (Choose TWO)
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 to grant least-privilege access to the storage account.
Correct answers: A and D. A: Enable encryption at rest using Azure Storage Service Encryption (SSE) which is enabled by default. D: Use Azure RBAC to control access to the storage account. B is wrong because data masking is for databases, not storage. C is wrong because firewall rules secure network access, not data at rest. E is wrong because audit logging is for monitoring, not encryption.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Use Azure RBAC to grant least-privilege access to the storage account.
Why this is correct
RBAC controls access, a security measure for data at rest.
Related concept
Authentication checks who the user is.
✗
Apply dynamic data masking to sensitive columns.
Why it's wrong here
Data masking is a database feature, not for Data Lake Storage.
✓
Enable Azure Storage Service Encryption (SSE) for data at rest.
Configure firewall rules to restrict network access.
Why it's wrong here
Firewall rules secure network access, not data at rest.
✗
Enable audit logging for the storage account.
Why it's wrong here
Audit logging is for monitoring, not encryption.
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.

Variation 1. Which TWO actions should you take to secure data at rest in Azure Data Lake Storage Gen2?
medium
✓ A.Enable Azure Storage Service Encryption (SSE) for data at rest
B.Enable diagnostic settings to audit access
C.Configure firewall rules to restrict network access
D.Enable soft delete for blobs
✓ E.Use Azure RBAC to grant least privilege access to storage accounts
Why A: Enabling encryption at rest (Azure Storage Service Encryption) and using Azure RBAC to control access are both security best practices. Option C is wrong because firewall rules are network-level, not data-at-rest. Option D is wrong because soft delete is for recovery, not security. Option E is wrong because diagnostic settings are for auditing, not encryption.
