Designing and Deploying Microsoft Exchange Server 2016 — Question 4

You have an Exchange Server 2016 organization.
All users work from a main office and use Microsoft Outlook 2016.
You recently ran the Microsoft Office 365 Hybrid Configuration Wizard and moved most of the user mailboxes to Exchange Online. A network administrator reports an increase in the amount of outbound SMTP traffic from the network.
You need to reduce the amount of bandwidth utilization for the outbound SMTP traffic.
What should you do?

Answer options

• A. From the Exchange Server organization, create a Receive connector that uses the IP address of Exchange Online as a remote range.
• B. From the public DNS zone, modify the MX record to point to Exchange Online.
• C. From the public DNS zone, modify the SRV record to point to Exchange Online.
• D. From the Exchange Server organization, create a Send connector that uses Exchange Online as an SMTP smart host.

Correct answer: B

Explanation

The correct answer is B because modifying the MX record to point to Exchange Online allows email to be routed directly to Exchange Online, which reduces the amount of SMTP traffic from the on-premises Exchange server. Options A and D do not address reducing outbound traffic effectively, while option C is not relevant for directing email flow.
