But according to this video in Server 2012 R2 there are no Web Agents, so the question states that the server is running Server 2012 R2, how could you configure something that doesn’t exist on that version of Windows. Is the question correct or am i missing something here?
“AD FS Web Agents
Web agents are not available in Windows Server 2012 R2 as they have been removed. In the other version of AD FS the name may be slightly different, but they form the same function. A vendor is free to add their own agents however the two web agents provided by Microsoft are “Claims-aware Agent” or “AD FS 1.1 Claims-aware Agent” and “Windows Token-based Agent” or “AD FS 1.1 Windows Token-based Agent”.”
Looks like from this link , it is IIS, i think it is a definite maybe
