Answer is B D is wrong - vCenter HA requires a single vCenter Server license. vCenter HA requires a Standard license. B is correct - vCenter HA network latency between Active, Passive, and Witness nodes must be less than 10 ms. The vCenter HA network must be on a different subnet than the management network. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-8FD87389-8CC9-4298-8B08-A1526FB44524.html
