Your company has a main office in London that contains 100 client computers. Three years ago, you migrated to Azure Active Directory (Azure AD). The company`s security policy states that all personal devices and corporate-owned devices must be registered or joined to Azure AD. A remote user named User1 is unable to join a personal device to Azure AD from a home network. You verify that User1 was able to join devices to Azure AD in the past. You need to ensure that User1 can join the device to Azure AD. What should you do? 

Answer options:

A. Assign the User administrator role to User1.
B. From the Device settings blade, modify the Maximum number of devices per user setting.
C. Create a point-to-site VPN from the home network of User1 to Azure.
D. From the Device settings blade, modify the Users may join devices to Azure AD setting.

B

The Maximum number of devices setting enables you to select the maximum number of devices that a user can have in Azure AD. If a user reaches this quota, they will not be able to add additional devices until one or more of the existing devices are removed. Incorrect Answers: C: Azure AD Join enables users to join their devices to Active Directory from anywhere as long as they have connectivity with the Internet. D: The Users may join devices to Azure AD setting enables you to select the users who can join devices to Azure AD. Options are All, Selected and None. The default is All.
