Using Microsoft Purview DLP to Prevent Sharing MRN via Email
This SC-900 practice question tests your understanding of describe the capabilities of microsoft compliance solutions. 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 compliance officer needs to create a policy that prevents users from sharing files containing medical record numbers (MRN) via email. Which Microsoft Purview solution should they use?
Answer choices
Why each option matters
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) is the correct solution because it is specifically designed to detect and block the sharing of sensitive information, such as medical record numbers (MRN), via email. DLP policies can inspect email content and attachments for patterns (e.g., regex for MRNs) and automatically enforce actions like blocking the message or notifying the user, preventing data exfiltration.
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
The trap here is that candidates often confuse sensitivity labels (which classify and protect data at rest) with DLP (which monitors and controls data in motion), leading them to choose A, even though labels alone cannot block email transmission of sensitive content.
Detailed technical explanation
How to think about this question
DLP policies in Microsoft Purview use deep content analysis, including exact data match (EDM) and machine learning classifiers, to identify sensitive data like MRNs even if they are embedded in complex formats or obfuscated. The policy can be scoped to Exchange Online, SharePoint, OneDrive, and Teams, and can trigger automated actions such as blocking the email, sending an incident report, or applying a 'block with override' option for compliant users. In a real-world scenario, a healthcare organization might configure a DLP rule to detect a 9-digit pattern (e.g., MRN format) and block the email while notifying the compliance officer via a policy tip.
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.
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.
