The answer is Microsoft Purview Data Map with automatic classification. This capability is correct because it uses scanning to inspect data across Azure SQL Database, Azure Data Lake Storage, and Microsoft 365, automatically applying sensitivity labels based on built-in or custom sensitive data types like credit card and passport numbers. On the Microsoft Cybersecurity Architect exam, this question tests your understanding of how Purview’s data governance components differ: Information Protection handles labeling and protection within Microsoft 365 but cannot scan external data sources, while DLP policies enforce rules after classification and Audit only logs activities. A common trap is confusing Data Map’s automatic classification with Information Protection’s manual or policy-based labeling—remember that Data Map is the scanner that finds the data, and Information Protection applies the label after it’s found. Memory tip: think “Map scans, Protection labels, DLP blocks, Audit tracks.”
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.
You are designing a solution for a multi-national corporation that uses Microsoft Purview to govern data across Azure SQL Database, Azure Data Lake Storage, and Microsoft 365. The data classification labels must be automatically applied based on sensitive data types such as credit card numbers and passport numbers. Which Microsoft Purview capability should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Purview Data Map with automatic classification
Option B is correct because Microsoft Purview Data Map with automatic classification scanning can scan data sources and apply sensitivity labels based on built-in or custom data types. Option A is wrong because Information Protection is for labeling and protection in Microsoft 365, not for scanning data sources. Option C is wrong because DLP policies are for preventing data loss, not for automatic classification. Option D is wrong because Audit is for logging activities.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 Purview Data Loss Prevention (DLP) policies
Why it's wrong here
DLP policies prevent data exfiltration but do not automatically classify data.
✗
Microsoft Purview Audit
Why it's wrong here
Audit logs activities but does not classify data.
✗
Microsoft Purview Information Protection
Why it's wrong here
Information Protection focuses on labeling and protection in Microsoft 365, not on scanning data sources.
✓
Microsoft Purview Data Map with automatic classification
Why this is correct
Data Map can scan multiple data sources and automatically apply sensitivity labels based on sensitive data types.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
