MS-102 Manage compliance by using Microsoft Purview Practice Question
This MS-102 practice question tests your understanding of manage compliance by using microsoft purview. 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 compliance officer needs to prevent users from sharing emails that contain credit card numbers with external recipients. When a user attempts to send such an email, it should be blocked immediately, and a policy tip should notify the user. Which Microsoft Purview solution should the officer configure?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
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
A Data Loss Prevention (DLP) policy is the correct solution because it is specifically designed to detect sensitive information, such as credit card numbers, in transit (e.g., email) and enforce actions like blocking the message and displaying a policy tip to the user. DLP policies use sensitive information types (e.g., Credit Card Number) and rules to inspect content in Exchange Online, SharePoint, OneDrive, and Teams, allowing real-time blocking with user notification. This directly meets the compliance officer's requirement to prevent external sharing and provide immediate feedback.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Data Loss Prevention (DLP) policy
Why this is correct
DLP policies can inspect email content for sensitive info and block delivery while showing a policy tip to the user.
Clue confirmation
The clue word "immediately / without restart" in the question point toward this answer.

✗
sensitivity label
Why it's wrong here
Sensitivity labels apply classification and encryption but do not enforce real-time blocking of outgoing emails based on content.
✗
retention label
Why it's wrong here
Retention labels manage retention and deletion, not content-based blocking or policy tips.
✗
An information barrier policy
Why it's wrong here
Information barriers prevent communication between specific groups but do not inspect message content for sensitive data.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Microsoft often tests the distinction between DLP policies and sensitivity labels, where candidates mistakenly think a sensitivity label alone can block email transmission, but labels require a DLP policy to enforce actions like blocking, while DLP policies can work independently of labels.
Detailed technical explanation
How to think about this question
Under the hood, a DLP policy in Microsoft Purview leverages the Exchange Transport Agent to inspect email messages in transit, matching patterns against built-in sensitive information types like Credit Card Number (which uses Luhn checksum validation and regex). The policy can be configured with an 'Action' to 'Block the message' and 'Notify the user with a policy tip', which is rendered in Outlook clients via the Exchange Web Services (EWS) or Outlook on the web. A subtle behavior is that DLP policy tips only appear in supported clients (Outlook desktop, Outlook on the web, Outlook for iOS/Android) and not in third-party email clients unless using Exchange mail flow rules.

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 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.
