Microsoft 365 Messaging — Question 14

You have a Microsoft Exchange Online tenant.
The mail exchanger (MX) record of your company points to a third-party message hygiene provider that forwards email messages to the tenant.
You need to ensure that Exchange Online can filter the email by using the original IP address of the sender's company.
What should you do?

Answer options

• A. Modify the Inbound connector to use the -EFSkipIPs parameter.
• B. Modify the Receive connector to use the -EFSkipIPs parameter.
• C. Enable DMARC.
• D. Create a remote domain.

Correct answer: A

Explanation

The correct answer is A because modifying the Inbound connector with the -EFSkipIPs parameter allows Exchange Online to recognize the original sender's IP address for filtering. Options B and D do not address the requirement for filtering based on the original IP, while option C, enabling DMARC, is related to authentication but does not directly influence IP-based filtering.
