Your network contains an Active Directory domain named contoso.com. The domain contains a member server named Server1 that has the Active Directory
Federation Services server role installed.
All servers run Windows Server 2012.
You complete the Active Directory Federation Services Configuration Wizard on Server1.
You need to ensure that client devices on the internal network can use Workplace Join.
Which two actions should you perform on Server1? (Each correct answer presents part of the solution. Choose two.)
A. Run Enable-AdfsDeviceRegistration -PrepareActiveDirectory.
B. Edit the multi-factor authentication global authentication policy settings.
C. Run Enable-AdfsDeviceRegistration.
D. Run Set-AdfsProxyProperties HttpPort 80.
E. Edit the primary authentication global authentication policy settings.
C. To enable Device Registration Service

Repeat this step on each federation farm node in your AD FS farm.
E. Enable seamless second factor authentication
Seamless second factor authentication is an enhancement in AD FS that provides an added level of access protection to corporate resources and applications from
external devices that are trying to access them. When a personal device is Workplace Joined, it becomes a `known’ device and administrators can use this
information to drive conditional access and gate access to resources. To enable seamless second factor authentication, persistent single sign-on (SSO) and
conditional access for Workplace Joined devices.
In the AD FS Management console, navigate to Authentication Policies. Select Edit Global Primary Authentication. Select the check box next to Enable Device
Authentication, and then click OK.
