A company wants to ensure that all outgoing emails containing sensitive financial data are encrypted automatically. The encryption should require the recipient to authenticate to read the message. Which Microsoft 365 solution should the administrator configure?
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.
Distractor review
Microsoft Defender for Office 365
This is a threat protection solution that safeguards against malicious links, attachments, and phishing. It does not provide outbound email encryption.
Best answer
Microsoft Purview Message Encryption
This solution provides encrypted email delivery, allowing only authenticated recipients to decrypt and read the message. It can be automated via rules.
Distractor review
Microsoft Purview Data Loss Prevention (DLP)
DLP policies detect and block sharing of sensitive information but do not encrypt messages. They can trigger encryption if combined with Message Encryption, but alone they do not encrypt.
Distractor review
Microsoft Purview Insider Risk Management
This tool helps identify, analyze, and remediate insider risks based on unusual user activities. It does not directly encrypt emails.
