- A
Azure Data Lake Storage (encrypted at rest), Azure Synapse Analytics (TDE and SSL), and Microsoft Purview
Azure Storage provides encryption at rest; Synapse supports TDE for at-rest and SSL for in-transit; Purview provides data lineage and auditing.
- B
Azure Blob Storage (encrypted at rest), Azure HDInsight, and Azure Log Analytics
Why wrong: Log Analytics is for monitoring, not data governance and auditing of data access.
- C
Azure SQL Database (TDE and SSL), Azure Analysis Services, and Microsoft Purview
Why wrong: Analysis Services is for analytical models, not data processing, and may not be the best choice for large-scale data processing.
- D
Azure Data Lake Storage (encrypted at rest), Microsoft Fabric, and Azure Monitor
Why wrong: Azure Monitor logs activity but does not provide the data governance and cataloging features of Purview.
Quick Answer
The correct combination is Azure Data Lake Storage, Azure Synapse Analytics, and Microsoft Purview because this trio addresses the full scope of data encryption at rest and in transit with auditing using Azure Purview. Azure Data Lake Storage automatically encrypts data at rest via Storage Service Encryption (SSE) with 256-bit AES, while Azure Synapse Analytics enforces Transparent Data Encryption (TDE) for at-rest protection and SSL/TLS for data in transit, ensuring end-to-end encryption for sensitive financial data. Microsoft Purview then provides the auditing layer by capturing data lineage, classification, and access activity logs, which is critical for compliance in regulated industries. On the DP-203 exam, this question tests your ability to map specific Azure services to layered security requirements—a common trap is choosing a single service like Azure SQL Database without considering the need for a separate auditing and governance tool. Remember the mnemonic “LSP” for Lake, Synapse, Purview: each handles a distinct pillar—storage encryption, compute encryption, and audit governance.
DP-203 Develop data processing Practice Question
This DP-203 practice question tests your understanding of develop 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.
You are designing a data processing solution for a financial services company. The solution must process sensitive customer data from multiple sources. You need to ensure that the data is encrypted at rest and in transit, and that access to the data is audited. Which combination of Azure services should you use?
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
Azure Data Lake Storage (encrypted at rest), Azure Synapse Analytics (TDE and SSL), and Microsoft Purview
Option A is correct because Azure Data Lake Storage provides encryption at rest using Azure Storage Service Encryption (SSE) with 256-bit AES, and Azure Synapse Analytics supports Transparent Data Encryption (TDE) for at-rest encryption and SSL/TLS for in-transit encryption. Microsoft Purview enables data governance and auditing by capturing lineage, classification, and access activity logs, meeting the compliance requirements for sensitive financial data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure Data Lake Storage (encrypted at rest), Azure Synapse Analytics (TDE and SSL), and Microsoft Purview
- ✗
Azure Blob Storage (encrypted at rest), Azure HDInsight, and Azure Log Analytics
Why it's wrong here
Log Analytics is for monitoring, not data governance and auditing of data access.
- ✗
Azure SQL Database (TDE and SSL), Azure Analysis Services, and Microsoft Purview
Why it's wrong here
Analysis Services is for analytical models, not data processing, and may not be the best choice for large-scale data processing.
- ✗
Azure Data Lake Storage (encrypted at rest), Microsoft Fabric, and Azure Monitor
Why it's wrong here
Azure Monitor logs activity but does not provide the data governance and cataloging features of Purview.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Monitor or Log Analytics with Microsoft Purview for auditing, but Microsoft Purview is the dedicated service for data governance, classification, and access auditing, while Azure Monitor is for operational monitoring and does not provide data-level audit trails.
Detailed technical explanation
How to think about this question
Azure Data Lake Storage Gen2 uses Azure Blob Storage's SSE with customer-managed keys (CMK) or Microsoft-managed keys, ensuring data at rest is encrypted with AES-256. Azure Synapse Analytics enforces TLS 1.2 for all connections and supports TDE for encrypting data files at rest, which is critical for financial compliance under regulations like PCI DSS. Microsoft Purview integrates with Azure Synapse to capture audit logs via Azure Monitor and provides a unified data catalog with lineage tracking, enabling full audit trails for sensitive data access.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
