Your company has a hybrid deployment of Office 365. You need to create a group. The group must have the following characteristics:
Group properties are synchronized automatically.
Group members have the ability to control which users can send email messages to the group.
What should you do?
A. Create a distribution group and configure the Mail Flow Settings.
B. Create a dynamic distribution group.
C. Create a new role group.
D. Create a distribution group and configure the Membership Approval settings.
I think corret answer is A.
A distribution group is a mail-enabled Active Directory distribution group object that can be used to distribute messages to a group of recipients. In this question, we have a hybrid deployment. This means that the on-premise Active Directory is synchronized to the Azure Active Directory. We can create the distribution group in the on-premise Active Directory and it will replicate to Azure Active Directory.
The Mail Flow Settings can be configured to control which users can send email messages to the group. In the Mail Flow Settings tab, double-click on Mail Delivery Restrictions to open the Mail Delivery Restrictions page. On this page, there is an “Accept Messages From..” section. In this section, select the “Only senders in the following list:” option. This will give you the option to list who can send email to the distribution group.
