The answer is Microsoft Purview Information Protection with auto-labeling policies for Azure Blob Storage. This service uses content scanning and machine learning to inspect blobs for protected health information, then automatically applies sensitivity labels that enforce restrictions like preventing external sharing, directly meeting the compliance requirement for PHI data. On the Microsoft Azure Security Engineer Associate AZ-500 exam, this question tests your ability to distinguish between services that enforce rules (Azure Policy), detect threats (Defender for Storage), or aggregate logs (Sentinel) versus those that actually inspect and label content. A common trap is confusing Microsoft Sentinel, a SIEM, with Purview’s labeling capabilities, or assuming Azure Policy can scan blob contents. Remember the memory tip: “Purview peeks at content, Policy only checks compliance.”
AZ-500 Secure compute, storage, and databases Practice Question
This AZ-500 practice question tests your understanding of secure compute, storage, and databases. 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 the security engineer for a healthcare company that uses Azure to store electronic health records (EHR) in Azure Blob Storage. Compliance requires that all data be encrypted at rest with customer-managed keys stored in a hardware security module (HSM), that the storage account be accessible only from a specific virtual network, and that all access to the storage account be logged and sent to a central security information and event management (SIEM) system. Additionally, you must ensure that any blobs containing protected health information (PHI) are automatically labeled with a sensitivity label that prevents them from being shared externally. You have decided to use Azure Key Vault Managed HSM for key storage, Azure Private Endpoint for network access, and Azure Monitor for logging. However, you are unsure how to automatically apply sensitivity labels to blobs based on content inspection. Which service should you use to achieve automatic labeling of PHI data in Azure Blob Storage?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Purview Information Protection with auto-labeling policies for Azure Blob Storage
Microsoft Purview Information Protection can automatically classify and label sensitive data in Azure Blob Storage using content scanning and machine learning. Option C is correct. Option A is incorrect because Azure Policy enforces rules but does not inspect content for labeling. Option B is incorrect because Microsoft Sentinel is a SIEM, not a labeling service. Option D is incorrect because Microsoft Defender for Storage provides threat detection but does not apply sensitivity labels.
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.
✗
Microsoft Defender for Storage with sensitivity labeling integration
Why it's wrong here
Defender for Storage detects threats but does not classify or label data.
✗
Azure Policy with custom policies to tag blobs containing PHI
Why it's wrong here
Azure Policy does not inspect blob content; it only evaluates metadata and configurations.
✓
Microsoft Purview Information Protection with auto-labeling policies for Azure Blob Storage
Why this is correct
Purview can scan blob content and automatically apply sensitivity labels based on data classification.

✗
Microsoft Sentinel with analytics rules to detect PHI and apply labels via automation
Why it's wrong here
Sentinel is for security monitoring, not content classification and labeling.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
