The answer is Microsoft Purview Data Loss Prevention (DLP). This is the correct choice because DLP policies are specifically designed to automatically detect sensitive content like the phrase 'Non-Public Material Information' in emails, then trigger actions such as displaying policy tips to educate senders before the message is sent, and enforcing encryption while blocking forwarding if the email is still transmitted. For the SC-900 exam, this scenario tests your understanding of how DLP integrates with retention labels to meet both security and compliance requirements—here, retaining the email for 7 years by applying a label automatically upon detection. A common trap is confusing DLP with Microsoft Purview Information Protection, but remember: DLP handles detection and enforcement actions (like encryption and blocking), while Information Protection focuses on classification and labeling. A helpful memory tip is "DLP detects and defends"—it spots the data and then applies the protective measures, including encryption, to prevent unauthorized sharing.
SC-900 Practice Question: Describe the capabilities of Microsoft compliance solutions
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 financial organization needs to automatically detect emails containing the phrase 'Non-Public Material Information' and apply a retention policy that retains those emails for 7 years. They also need to train senders with a policy tip before sending, and if they still send the email, it should be encrypted and blocked from being forwarded outside the organization. Which Microsoft Purview solution should they use?
Why wrong: This manages retention and deletion, but does not detect content or enforce actions like encryption and blocking.
B
Microsoft Purview Data Loss Prevention (DLP)
DLP can detect sensitive information, provide policy tips, and automatically encrypt, block, and apply retention labels to messages.
C
Microsoft Purview Communication Compliance
Why wrong: Communication Compliance is for monitoring communications for policy violations (e.g., insider trading) but not for enforcing DLP actions like encryption or blocking.
D
Microsoft Purview Audit
Why wrong: Audit provides logging and investigation capabilities, not proactive detection and enforcement of retention and protection policies.

Correct answer & explanation
✓
Microsoft Purview Data Loss Prevention (DLP)
Microsoft Purview Data Loss Prevention (DLP) is the correct solution because it can automatically detect sensitive content (e.g., 'Non-Public Material Information') in emails, apply policy tips to train senders before sending, enforce encryption, and block forwarding outside the organization. DLP policies also integrate with retention labels to retain emails for a specified period, such as 7 years, by applying a retention label automatically when the sensitive content is detected.
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 Data Lifecycle Management (retention only) with DLP (detection + action), or assume Communication Compliance handles all email content monitoring, but DLP is the only solution that combines real-time content detection, user training via policy tips, and automated enforcement actions like encryption and forwarding blocks.
Detailed technical explanation
How to think about this question
Under the hood, a DLP policy for Exchange Online uses transport rules (mail flow rules) with conditions like 'Any attachment's content contains' or 'Subject or body contains' patterns, and actions such as 'Prepend subject' with a policy tip, 'Encrypt the message' via Azure Rights Management (RMS), and 'Reject the message' or 'Redirect it' to block forwarding. The retention requirement is met by configuring a DLP action to apply a retention label (e.g., '7-Year Retention') that triggers a retention policy in the Microsoft 365 compliance center, ensuring the email is preserved for exactly 7 years even if deleted by the user.

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.
