Correct Answer: AB
The output shows two mail exchange (MX) records for the example.com domain with different preference values. The MX record with the lower preference value (mx.hosted.com with a preference of 10) is prioritized higher. This means external MTAs will send email to mx.hosted.com first, and only if it is unreachable, they will then send emails to mx.example.com which has a higher preference value of 20. Therefore, the primary MTA for the example.com domain is mx.hosted.com, and if it becomes unreachable, then mx.example.com is used. Load balancing is not applicable here as it applies to servers with equal preference values.
