DP-203 Develop data processing Practice Question
You are designing a data processing solution for a large e-commerce company. The data includes sensitive customer information that must be encrypted at rest and in transit. The solution uses Azure Data Lake Storage Gen2 and Azure Databricks. Compliance requires that all access to the data is logged and monitored. Which combination of security features 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
✓
Enable Azure Storage encryption at rest, enforce HTTPS, and configure diagnostic settings to log all read/write operations.
It covers encryption at rest (Azure Storage encryption), encryption in transit (HTTPS), and logging via diagnostic settings for read/write operations. Option A is incorrect because Azure RBAC does not log access details; it only controls permissions. Option B is incorrect because Azure Firewall restricts network traffic but does not provide logging of data access or encryption. Option D is incorrect because Transparent Data Encryption (TDE) is a feature for Azure SQL databases, not for Azure Data Lake Storage Gen2.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable Azure RBAC for storage and use Azure AD authentication.
Why it's wrong here
Does not provide access logging.
- ✗
Use Azure Firewall to restrict access and enable Azure AD Authentication for Databricks.
Why it's wrong here
Firewall does not log data access.
- ✓
Enable Azure Storage encryption at rest, enforce HTTPS, and configure diagnostic settings to log all read/write operations.
Why this is correct
Meets all requirements.
- ✗
Enable transparent data encryption (TDE) on the storage account and use service endpoints.
Why it's wrong here
TDE is for SQL, not Data Lake.

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 |
