HOTSPOT
Your network contains an Active Directory domain named contoso.com. The domain
contains an enterprise certification authority (CA).
The domain contains a server named Server1 that runs Windows Server 2012 R2. You
install the Active Directory Federation Services server role on Server1.
You plan to configure Server1 as an Active Directory Federation Services (AD FS) server.
The Federation
Service name will be set to adfs1.contoso.com.
You need to identify which type of certificate template you must use to request a certificate for AD FS.
