Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Microsoft Purview Data Loss Prevention (DLP)
DLP can detect sensitive data and apply actions like blocking or notifying, but to automatically encrypt the email, DLP uses an action that invokes Message Encryption. Message Encryption is the underlying technology that encrypts the email.
B
Best answer
Microsoft Purview Message Encryption
Message Encryption allows sending encrypted emails to any recipient and supports secure reply without separate sign-up. It can be triggered automatically by a DLP policy when sensitive data is detected.
C
Distractor review
Microsoft Purview Information Protection (sensitivity labels)
Sensitivity labels can be applied manually or automatically to emails, but they rely on the recipient's ability to read protected messages. Message Encryption is specifically designed for sending encrypted emails to external users without requiring them to have Microsoft Entra ID accounts.
D
Distractor review
Microsoft Defender for Office 365
Defender for Office 365 provides anti-phishing, anti-malware, and safe attachments, but does not directly provide email encryption capabilities.
Common exam trap
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.

FAQ
Questions learners often ask
What does this MS-900 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Microsoft Purview Message Encryption — Microsoft Purview Message Encryption allows organizations to send encrypted emails to any recipient. It supports 'encrypt-only' and 'forward' rights, and recipients can reply encrypted without additional accounts. DLP policies can trigger automatic encryption, but the core encryption capability is Message Encryption. Azure Information Protection is for persistent protection, but for email encryption specifically, Message Encryption is the term used in M365 compliance. Sensitivity labels can also apply encryption, but the scenario describes automatic encryption triggered by content (bank account numbers) which is best achieved by a DLP policy that applies Message Encryption. However, the most direct answer is Microsoft Purview Message Encryption because it is the feature that provides the encryption and the reply-back capability.
