When populating the VxRail Installation wizard for an external vCenter solution, what is the correct format for hostnames?

When populating the VxRail Installation wizard for an external vCenter solution, what is the correct format for hostnames?
A. vCenter and PSC should use FQDN, VxRail Manager should use host name only
B. VxRail Manager and vCenter should use FQDN; PSC should you host name only
C. vCenter, PSC, and VxRail Manager should use FQDN
D. vCenter, PSC, and VxRail Manager should use host name only

Answer: C
Explanation:
Specify the name of the cluster that will be created by VxRail in the selected datacenter when the
cluster is built. It will also be the name of the distributed switch. This name must be unique and not used
anywhere in the datacenter on the Customer Supplied vCenter Server.
