The answer is Microsoft Purview Data Map, Data Catalog, and Data Estate Insights. These three components work together to identify sensitive data across a hybrid data estate, including on-premises SQL Server, Azure SQL Database, and Amazon S3. The Data Map provides the underlying scanning and classification engine that discovers and catalogs sensitive data types across all sources, while the Data Catalog organizes these assets into a searchable inventory with business context. Data Estate Insights then aggregates scan results into dashboards that reveal where sensitive data resides and highlights security posture risks, enabling targeted classification and protection actions. On the Microsoft Cybersecurity Architect exam, this question tests your understanding of how Purview’s core components collaborate for cross-platform sensitive data discovery, not just Azure-native sources. A common trap is to select only Azure Purview or Azure Policy, but the correct trio must include the scanning foundation (Data Map), the organizational layer (Data Catalog), and the visibility layer (Data Estate Insights). Memory tip: Map, Catalog, Insights—scan, organize, visualize.
SC-100 Practice Question: Design solutions that align with security best practices and priorities
This SC-100 practice question tests your understanding of design solutions that align with security best practices and priorities. 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 security strategy using Microsoft Purview. They need to identify sensitive data across their data estate, including on-premises SQL Server, Azure SQL Database, and Amazon S3. Which THREE components should they use? (Choose three.)
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 Estate Insights
Microsoft Purview Data Estate Insights provides visibility into data estate health and security posture, including sensitive data discovery across on-premises SQL Server, Azure SQL Database, and Amazon S3. It aggregates scan results and offers dashboards to identify where sensitive data resides, enabling targeted classification and protection actions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Microsoft Purview Compliance Manager
Why it's wrong here
Compliance Manager helps manage compliance activities, not data scanning.
✓
Microsoft Purview Data Map
Why this is correct
Data Map scans and classifies data sources.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse Compliance Manager (a compliance posture tool) with data discovery capabilities, or think External Identities (an identity feature) is relevant to scanning data sources, when in fact only Data Map, Data Catalog, and Data Estate Insights form the core trio for sensitive data identification across hybrid estates.
Detailed technical explanation
How to think about this question
Under the hood, Purview Data Map uses a scanning engine that connects to data sources via connectors (e.g., SQL Server via TDS protocol, Azure SQL via ADO.NET, Amazon S3 via REST API) and applies built-in or custom classification rules (e.g., regex patterns for credit card numbers) to label sensitive data. Data Catalog then registers these classified assets as searchable metadata entries, enabling data stewards to manage lineage and governance. In a real-world hybrid scenario, the Data Map’s ability to scan across on-prem and cloud sources in a unified manner is critical for consistent policy enforcement.

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.

Variation 1. A company uses Microsoft Purview to manage data governance. They need to classify sensitive data automatically in Azure SQL Database. What should they configure?
medium
A.Microsoft Defender for Cloud regulatory compliance
✓ B.Microsoft Purview Data Map scanning rules
C.Microsoft Sentinel data connectors
D.Microsoft Entra ID Protection
Why B: Microsoft Purview Data Map scanning rules are the correct choice because they enable automated classification of sensitive data in Azure SQL Database by scanning the database schema and content against built-in or custom sensitive data types. This is the native mechanism within Purview to discover and label sensitive columns, such as credit card numbers or PII, directly in Azure SQL Database.
