Your company has a Microsoft Exchange Server 2019 server named EX01. EX01 has the default Receive connectors. EX01 receives Internet email on port 25 from an appliance in the company's perimeter network.
The company has an application named App1 that can only send email on port 25. The application administrator requests that you enable App1 to route email through EX01 for delivery.
You need to ensure that EX01 only accepts email from the appliance and App1.
Solution: You modify the remote IP address ranges of the default frontend Receive connector.
Does this meet the goal?

Answer options

Correct answer: A

Explanation

The solution of modifying the remote IP address ranges of the default frontend Receive connector is effective because it restricts email acceptance to only specified IP addresses, which include both the appliance and App1. Other options would either not restrict access correctly or fail to meet the requirement of allowing only those two sources to send emails through EX01.
