The answer is enabling diagnostic settings for the storage account and sending logs to Azure Sentinel. This is correct because Microsoft Defender for Cloud, specifically Azure Defender for Storage, provides built-in security threat detection for ADLS Gen2 by continuously analyzing storage telemetry and applying machine learning to identify anomalies, malware, and suspicious activities like unauthorized access or data exfiltration. On the DP-203 exam, this concept tests your understanding of how to operationalize threat detection through log integration rather than relying solely on native alerts; a common trap is confusing enabling diagnostic settings with simply turning on logging in the portal. Remember that Azure Sentinel acts as the SIEM where logs are aggregated for advanced hunting and incident response, while Defender for Cloud provides the initial detection layer. A useful memory tip: think of Defender for Cloud as the “detective” and Sentinel as the “case file” — both are needed for complete threat monitoring.
DP-203 Practice Question: Monitor and optimize data storage and processing
This DP-203 practice question tests your understanding of monitor and optimize data storage and 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 when monitoring Azure Data Lake Storage Gen2 to detect security threats?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Azure Security Center and Azure Defender for Storage.
Azure Security Center (now Microsoft Defender for Cloud) with Azure Defender for Storage provides built-in threat detection for Azure Data Lake Storage Gen2, including anomaly detection, malware scanning, and alerts for suspicious activities like unauthorized access or data exfiltration. This is a primary action for detecting security threats because it continuously monitors storage telemetry and applies machine learning to identify potential security incidents.
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.
✓
Use Azure Security Center and Azure Defender for Storage.
Why this is correct
Azure Defender provides threat detection and alerts for storage accounts.
Related concept
Read the scenario before looking for a memorised answer.
✓
Enable diagnostic settings for the storage account and send logs to Azure Sentinel.
Why this is correct
Diagnostic logs capture operations and can be analyzed for security events.
Related concept
Read the scenario before looking for a memorised answer.
✗
Enable soft delete for blobs to recover from accidental deletions.
Why it's wrong here
Soft delete is a recovery feature, not a threat detection mechanism.
✗
Configure firewall and virtual network service endpoints.
Why it's wrong here
Network restrictions reduce exposure but do not detect threats.
✗
Set up alerting on the 'Transactions' metric.
Why it's wrong here
Metrics alone do not detect security threats; they measure performance.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse data protection features (like soft delete) or network controls (like firewalls) with active threat detection, overlooking that only dedicated security monitoring tools (Azure Security Center/Defender and Sentinel) can identify and alert on security threats in real time.
Detailed technical explanation
How to think about this question
Azure Defender for Storage uses behavioral analytics and threat intelligence feeds to detect anomalies such as unusual access patterns, suspicious IP addresses, or attempts to access sensitive data. When enabled, it analyzes storage telemetry (e.g., read/write operations, authentication failures) and can trigger security alerts in Azure Sentinel for further investigation. For Data Lake Storage Gen2, this includes monitoring hierarchical namespace operations and ACL changes, which are critical for detecting privilege escalation or data tampering.

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.
