Vmware vCenter Server is running within a virtual machine (VM) that is part of a VMware HA and DRS cluster. The vCenter Server VM has been tested and can successfully vMotion migrate between all hosts in the cluster. DRS is configured for partial automation.
What happens if the ESX host that is currently running the vCenter Server VM experiences a power outage?
A.
VMware HA will restart the vCenter Server VM on another host
B.
vCenter Server will remain offline, but all VMs on the remaining hosts will continue without interruption
C.
This situation cannot occur because vCenter Server cannot be installed on a VMware HA cluster
D.
All DRS cluster operations will be unavailable until the failed ESX Host is brought back online
This is a recurrent tricky question VMware places every exam. Forbes at vReference.com states very clear:
“Master host (wich is an ESXi elected one) responsabilities:
…
Monitoring the power state of all protected firtual machines. If one virtual machine fails, the master host ensures that it is restarted. Using a local placement engine, the master host also determines where the restart should be done.”
So restarting VM responsability is not a vCenter responsability, but Master Host one. That’s why if VM vCenter fails, it can be restarted easy by Master Host”
