You subscribe to Office 365.
You plan to implement single sign-on.
You need to deploy Active Directory Federation Services (AD FS) to a server for the planned implementation.
Which deployment methods should you use? (Each correct answer presents a complete solution.Choose all that apply.)
A.
On a server that runs Windows Server 2008 R2, download and install AD FS 2.0.
B.
On a server that runs Windows Server 2008, download and install AD FS 2.0.
C.
On a server that runs Windows Server 2008, install the AD FS server role.
D.
On a server that runs Windows Server 2008 R2, install the AD FS server role.
AD FS has a separate installation package (referred to as AD FS 2.0) for the Windows Server 2008 and Windows Server 2008 R2 operating system platforms. AD FS can also be installed by adding the Federation Service server role as part of the Windows Server 2012 operating system.
I think this should be A and B.
