Good question; I have seen this issue also.
My experience is a bit different, though. I see in the authenticated_hosts.csv that MVM attempts both SSHv2 Certificate and access via the five Windows methods that you show.
Here is an example. (host id edited)
IP Address | DNS Name | NetBios Name | Asset Label | Asset Criticality | Operating System | Asset Owner | SSHv2 Certificate | SSHv2 Credential | SSHv1 | Telnet | WMI Accessible | Remote Registry | Remote File System Access | Null Session | Administrator Authentication | Error Code | Error Description |
1.2.3.4 | anyhost.com | anyhost | 10016058 | 3 | Windows Server 2008 (Service Pack 2, Server, SQL Server, [++]) | user | noAccess |
