The correct choice is Data Loss Prevention (DLP) in Microsoft Purview. This feature is specifically designed to automatically detect sensitive information, such as credit card numbers, and enforce protective actions like blocking transmission or encrypting content across emails and documents. For the SC-900 exam, this question tests your ability to distinguish between Purview’s core compliance solutions: DLP focuses on policy-driven detection and protection of data in transit and at rest, whereas Information Protection deals with sensitivity labels and encryption, Data Lifecycle Management handles retention, and Insider Risk Management monitors user behavior. A common trap is confusing DLP with Information Protection, but remember that DLP is the active “guard” that scans and acts on sensitive data automatically. A helpful memory tip: DLP stands for “Detect, Lock, Protect”—if you need to find and shield specific data patterns like credit card numbers, DLP is your answer.
SC-900 Practice Question: Describe the concepts of security, compliance, and identity
This SC-900 practice question tests your understanding of describe the concepts of security, compliance, and identity. 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.
Your organization is implementing Microsoft Purview to manage data compliance. They need to automatically detect and protect credit card numbers in emails and documents. Which Microsoft Purview feature should they configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Data Loss Prevention (DLP)
Data Loss Prevention (DLP) policies in Microsoft Purview can automatically detect sensitive information like credit card numbers and apply protective actions, such as blocking or encrypting the content. Information Protection refers to sensitivity labels and encryption, but DLP is the feature that uses policies to detect and protect data in transit and at rest. Data Lifecycle Management handles retention and deletion. Insider Risk Management focuses on user behavior.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 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.

Variation 1. An organization uses Microsoft Purview to manage data compliance. They need to automatically detect and protect credit card numbers stored in SharePoint Online. Which Microsoft Purview solution should they implement?
medium
A.Microsoft Purview Audit
✓ B.Microsoft Purview Data Loss Prevention
C.Microsoft Purview Information Protection
D.Microsoft Purview Data Lifecycle Management
Why B: Data Loss Prevention (DLP) policies can identify sensitive data like credit card numbers and apply protection actions such as blocking access. Information Protection (sensitivity labels) classifies data but does not automatically detect and protect specific patterns like credit card numbers without DLP integration.
