Exam MS-203 topic 2 question 1 discussion

Any anonymous applications, or appliance that needs to be able to send mail requires an SMTP relay, given answer is correct.

C is correct

C is correct

Answer C is in essence the least evil, aka you come to it by principle of exclusion of the other answers: D is completely out of topic; A is wrong because you need a licensed mailbox for SMTP AUTH; B is simply wrongly formulated - you need to configure the inbound connector based on IP addresses. And no, C is NOT the "Direct Send" option. Believe me, Direct Send would be the best answer here (satisfies the requirement to send to Finance, aka internal users only), but alas it is not available. C is actually the "SMTP relay" option from this documentation: https://learn.microsoft.com/en-us/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-microsoft-365-or-office-365

yes, C is correct.

The finance department at your company reports that email delivery from several printers fails after Exchange Server 2019 is decommissioned. You need to ensure that the printers can deliver email successfully to the users in the finance department. Based on what question asks you can go with B or C (YES, B is LESS secure, but still..).

It's also called, by Microsoft, as a "Direct Send".

C is correct.
