You have an on premises Exchange organization. The organization plans to migrate to Exchange Online.
Users report that after their mailboxes are migrated to Exchange Online they are no longer able to send
email 10 a specific dynamic distribution list. All other distribution lists work as expected.You need to resolve the issue.
What should you do?
A.
In the Active Directory Synchronization Services console, change the connector filter to include
dynamic distribution lists.
B.
In Office 365, re-create the dynamic distribution list.
C.
Run the following Windows PowerShell cmdlet:
Set- DynamicDistributionGroup
D.
Reduce the number of members in the distribution list to fewer than 1,500 contacts.
Correct.
Hope this helps: http://blogs.perficient.com/microsoft/2014/10/office-365-dynamic-distribution-groups-in-exchange-hybrid/
Could also be C, unless there is a space (Set- DynamicDistributionGroup) on the test
This problem occurs if the dynamic distribution group was set up before the environment became a hybrid deployment and if the dynamic distribution group uses filters to include only mailboxes. Mailboxes that are migrated to Office 365 become mail-enabled users in the on-premises directory.
Solution:
Set-DynamicDistributionGroup -Identity [email protected] -IncludedRecipients “MailboxUsers,MailContacts” -RecipientFilter {((RecipientType -eq ‘UserMailbox’ -or ‘MailUser’ -or ‘MailContact’))}

I think the answer is C. But I have to say the questions is poorly put together..

What the link says above is you create a contact in Exchange online for the DDG, you don’t recreate the group in Exchange online. You won’t find this option anywhere (recreating the DDG in exchange online). The only thing you will find in the link above is Set-DynamicDistributionGroup.
PROBLEM
You have a hybrid deployment of Exchange Online in Office 365 and on-premises Exchange Server. In this environment, certain members of a dynamic distribution group do not receive email messages.
CAUSE
This problem occurs if the dynamic distribution group was set up before the environment became a hybrid deployment and if the dynamic distribution group uses filters to include only mailboxes. Mailboxes that are migrated to Office 365 become mail-enabled users in the on-premises directory.
SOLUTION
Use the Set-DynamicDistributionGroup cmdlet to update the filters for the dynamic distribution group to include mail-enabled users.

“C” is the correct answer, you need to update the filter because the DDG was created before the setup, therefore you need to run the PS cmdlet to update the filter and fix the problem.
