  • HA will continue to work. It is configured through vCenter Server (i.e. vCenter Server configures the hosts), however it does not need vCenter Server to work. (see the link I provided in your other thread)
  • DRS will not work. Moving the VM's between hosts is a vCenter Server function.
  • FT will continue to work for the configured VMs. However in case of a failover, no new Secondary will be created.

HA will still work if its been configured vcenter is not required for HA to function, only required to configue HA.

DRS requires vmotion which is a vcenter function so it will stop functioning.

FT im not 100% but i belive its the same as HA once configured through vcenter it will still function if vcenter was to go down. The primary and secondary vm exchange heartbeats to make sure both are available and if not then it fails over without the need of vcenter. but if vcenter is unavailable and and FT has failed to the secondary i believe you will need vcenter up and available to set it back up.

Cheers
