Q. In Windows Server 2016 Failover Cluster are objects still created in Active Directory?
A. Windows Server 2016 introduces the ability for nodes in a cluster to be part of different domains and even part of workgroups. In these mixed-domain/workgroup scenarios objects are not created in AD for the cluster name object (CNO) of service objects and instead DNS entries are used in the same manner as AD-detached clusters in Windows Server 2012 R2. When all nodes are in the same AD domain then objects are created in AD in a similar manner to non-AD-detached clusters.
