This SC-100 practice question tests your understanding of design solutions that align with security best practices and priorities. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 uses Microsoft Purview to manage data governance. They need to classify sensitive data automatically in Azure SQL Database. What should they configure?
Microsoft Defender for Cloud regulatory compliance
Why wrong: Defender for Cloud assesses compliance, does not classify data.
Microsoft Purview Data Map scanning rules
Purview Data Map scans and classifies data sources.
Microsoft Sentinel data connectors
Why wrong: Sentinel ingests logs, does not classify data.
Microsoft Entra ID Protection
Why wrong: Entra ID Protection is for identity risk, not data classification.
Answer choices
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 scanning rules
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Microsoft Defender for Cloud regulatory compliance
Why it's wrong here
Defender for Cloud assesses compliance, does not classify data.
Microsoft Purview Data Map scanning rules
Why this is correct
Purview Data Map scans and classifies data sources.

Microsoft Sentinel data connectors
Why it's wrong here
Sentinel ingests logs, does not classify data.
Microsoft Entra ID Protection
Why it's wrong here
Entra ID Protection is for identity risk, not data classification.
Common exam traps
The trap here is that candidates often confuse Microsoft Defender for Cloud's regulatory compliance dashboard with actual data classification, but Defender for Cloud only checks configuration settings against compliance frameworks, not the content of the data itself.
Detailed technical explanation
Under the hood, Purview Data Map scanning rules use a managed runtime to connect to Azure SQL Database via a system-assigned managed identity or service principal, then execute a scan that inspects column metadata and sample rows against a set of classification rules (e.g., regex patterns for Social Security numbers). The scan results populate the Purview Data Catalog with sensitivity labels and classifications, which can then trigger downstream policies like data loss prevention (DLP) or access controls. A subtle behavior is that scanning rules require the database to have the 'Allow Azure services and resources to access this server' firewall setting enabled, and the scan can be scheduled to run incrementally to detect new or changed data.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
