Under which condition will VMware HA restart the failed application?

An application in a virtual machine has failed. The virtual machine can still be accessed.
Under which condition will VMware HA restart the failed application?

A.
VMware HA will never restart the application.

B.
VMware HA will restart the application every time, as long as the cluster is not red.

C.
VMware HA will restart the application every time, as long as the Restart Priority is
not set to Disabled.

D.
VMware HA will only restart the application if the VMware tools are running.

Explanation:
vSphere Availability Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 23.
VM Monitoring restarts individual virtual machines if their VMware Tools heartbeats are
not received within a set time. VMware HA cannot restart a failed application on a guest,
as it is only monitoring the virtual machine. Therefore A is correct.
