The answer is Microsoft Purview Data Map and Sensitivity Labels. Purview Data Map automatically discovers and classifies sensitive data in Azure Blob Storage by scanning for patterns like credit card numbers or health records, while Sensitivity Labels then enforce protection by applying encryption or access restrictions directly to the blobs. On the Microsoft Cybersecurity Architect exam, this pairing tests your understanding of how classification and protection work as separate but complementary layers—a common trap is confusing Purview’s classification role with Azure Policy or DLP, which handle governance and endpoint security respectively. Remember the mnemonic “Map then Label” to recall that discovery must precede protection, and that Blob Storage classification relies on Purview’s native scanning, not Microsoft 365 tools.
SC-100 Practice Question: Design security solutions for applications and data
This SC-100 practice question tests your understanding of design security solutions for applications and data. 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.
A company is designing a data classification strategy using Microsoft Purview. They need to automatically classify and protect sensitive data stored in Azure Blob Storage. Which TWO capabilities should they use? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Sensitivity labels
Microsoft Purview Data Map provides auto-discovery and classification of data assets, and Sensitivity labels can apply protection. Option A and Option C are correct. Option B is wrong because DLP policies are for endpoint and Microsoft 365, not for Azure Blob. Option D is wrong because Information Barriers are for restricting communication, not classification. Option E is wrong because Azure Policy is for governance, not data classification.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Data Loss Prevention (DLP) policies
Why it's wrong here
DLP policies in Purview are for Microsoft 365 data, not Azure Blob Storage.
✗
Information Barriers
Why it's wrong here
Used to restrict communication between groups, not for data classification.
✓
Microsoft Purview Data Map
Why this is correct
Automatically discovers and classifies data assets across sources, including Azure Blob.

✗
Azure Policy
Why it's wrong here
Azure Policy enforces compliance rules, not data classification.
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.
Detailed technical explanation
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.
