Question
You implement Safe Attachments policies in Microsoft Defender for Office 365.
Users report that email messages containing attachments take longer than expected to be received.
You need to reduce the amount of time it takes to deliver messages that contain attachments without compromising security. The attachments must be scanned for malware, and any messages that contain malware must be blocked.
What should you configure in the Safe Attachments policies?
- A. Dynamic Delivery Correct
- B. Replace
- C. Block and Enable redirect
- D. Monitor and Enable redirect
Explanation
Dynamic Delivery delivers the message body immediately with a placeholder for each attachment while the attachment is scanned in the sandbox, then reattaches it if it is clean, so users are not delayed and attachments are still scanned. Block holds the whole message until scanning finishes, which is the delay users report. Monitor delivers malware rather than blocking it, and Replace is a legacy action that strips attachments rather than speeding delivery.
