The answer is a Data Loss Prevention (DLP) policy. This is correct because a Microsoft Purview DLP policy is specifically designed to detect sensitive information types—such as credit card numbers—and enforce protective actions like blocking external sharing while displaying a customizable policy tip to the user. On the SC-900 exam, this question tests your understanding of how DLP policies differ from sensitivity labels and insider risk management; a common trap is choosing sensitivity labels, but remember that labels primarily classify and protect data through encryption or marking, while the actual block action on sharing is enforced by DLP. For exam day, keep this memory tip in mind: "DLP blocks the share; labels just label the care."
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.
A company uses Microsoft Purview to classify and protect data. They need to ensure that when a user attempts to share a file containing a credit card number externally, the file is blocked and the user is prompted with a policy tip. Which type of Microsoft Purview policy 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) policy
DLP policies can detect sensitive data like credit card numbers and enforce actions such as blocking sharing with a policy tip. Sensitivity labels require manual application or auto-labeling, but the block action is defined by DLP. Insider Risk Management focuses on risky user activities.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Retention policy
Why it's wrong here
Retention policies manage data lifecycle, not detection or blocking of sensitive data.
✗
Insider Risk Management policy
Why it's wrong here
Insider Risk Management identifies risky behavior but does not block data sharing in real-time.
✗
Sensitivity label policy
Why it's wrong here
Sensitivity labels can be auto-applied but do not directly block sharing; DLP enforces protection actions.
✓
Data Loss Prevention (DLP) policy
Why this is correct
DLP policies can detect credit card numbers and block external sharing with a policy tip.

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.

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. Your company uses Microsoft Purview Information Protection to classify sensitive data. A user reports that when they try to share a document containing a credit card number via email, the email is blocked. Which Purview feature is most likely causing this behavior?
hard
✓ A.Data Loss Prevention (DLP) policy
B.Audit log
C.Sensitivity label
D.Retention label
Why A: Option A is correct because Data Loss Prevention (DLP) policies can block emails containing sensitive data. Option B is wrong because sensitivity labels apply metadata but don't block actions. Option C is wrong because retention labels manage retention, not blocking. Option D is wrong because audit logs record events but don't enforce blocks.
