Exam MS-203 topic 1 question 61 discussion

Actual exam question from Microsoft's MS-203

Question #: 61
Topic #: 1

You have a hybrid deployment that contains a Microsoft Exchange Online tenant and an on-premises Exchange Server 2019 server named Server1. All users use an email address suffix of @contoso.com.
You migrate 200 mailboxes from Server1 to Exchange Online by using Exchange PowerShell cmdlets. Users hosted on Server1 can send email messages to the migrated mailboxes.
In Microsoft 365, you create a new mailbox that uses an email address of [email protected].
When email is sent from the mailboxes hosted on Server1 to [email protected], the senders receive a non-delivery report (NDR) that contains the following text:
"550 5.1.10 RESOLVER.ADR.RecipientNotFound;
Recipient not found by SMTP address lookup."
You verify that Microsoft 365 mailboxes can send email to [email protected] successfully.
You delete the user account and mailbox of User1.
You need to ensure that when new mailboxes are created, all the users at your company can exchange email successfully
Which two actions should you perform? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

A. From Azure AD Connect, modify the synchronization settings
B. From Server1, run the New-RemoteMailbox cmdlet
C. From Server1, run the Enable-Mailbox cmdlet
D. From the on-premises network, create new mailboxes, and then migrate the mailboxes to Microsoft 365
E. From the Exchange admin center, modify the properties of the Outbound connector

Suggested Answer: BD 🗳️
The problem happens because the on-premise Exchange server is not aware of the existence of the mailbox created in Exchange Online. To prevent this happening, new mailboxes need to be created from the on-premise Exchange server.
You can create on Exchange Online mailbox from the on-premise server by running New-RemoteMailbox cmdlet. Alternatively, you can create a local mailbox on the on-premise server and then migrate the mailbox to Exchange Online.

As per best practices, in Exchange hybrid mode, users and mailboxes should be created in on-prem Exchange and then sync user to Office 365 and migrate mailbox to office 365.

Selected Answer: BE

The question states "should" not "can" this tells me there are to actions to perform B wil in fact create the mailbox in office, however, the on prem users are not able to mail to Office. Therefor the connector to office seems broken. There should be made a connector with a filter scope for Contoso.com directing all mail to office. that way the users can in fact mail to office. Of course the domain should not be authoritive on-prem to be able to forward mail to addressed not found on prem.
