Exam SC-100 topic 2 question 34 discussion

Definitely the DNS records. You would need to change the MX Records to make sure they point to Microsoft. i.e. - "0 <your domain>.mail.protection.outlook.com". The Exchange Online connectors would only reroute the email to Microsoft if you configure it that way but if the MX records are still pointing to the 3rd party filtering tool's domain (for example Proofpoint). the emails are still going to the 3rd party's filtering tool and not to Microsoft directly.

To ensure that all incoming email is scanned exclusively by Microsoft Defender for Office 365, you need to modify the DNS records. Specifically, you should update the MX (Mail Exchange) records to point to Microsoft Defender for Office 365 instead of the third-party cloud service. This change will route all incoming email through Defender for Office 365 for scanning and protection.
