What happens if an ESXi 5.x host that is running the vCenter Server virtual machine experiences a power outage

vCenter Server is running in a virtual machine that is part of a vSphere DRS cluster. The vCenter Server virtual machine has been tested and can successfully migrate with vMotion between all ESXi hosts in the cluster. DRS is configured for partial automation.

What happens if an ESXi 5.x host that is running the vCenter Server virtual machine experiences a power outage?

A.
All DRS cluster operations will be unavailable until the failed ESXi host is brought back online.

B.
vCenter Server will remain offline, but all virtual machines on the remaining hosts will continue without interruption.

C.
This situation cannot occur, because vCenter Server cannot be installed on a virtual machine in a vSphere DRS cluster.

D.
vSphere will restart the vCenter Server virtual machine on another host.

      D would require HA to be configured. Given that HA is not specified in the question, we can’t assume it is.

      Without HA, vCenter would not be rebooted and therefore would remain offline. VM’s would continue to run on the unaffected host.

    why is A incorrect? DRS cluster operations will be unavailable until the failed ESXi host (with the vCenter VM) comes back.

  2. ELMO says:

    Other Exam sites list this question as HA and DRS cluster , and thats a no brainer , VCenter VM will be restarted due to HA , and DRS will eventually load balance Hosts if Fully automated .

    In This question as it read ONLY DRS ( and yes you “can” enable on DRS if want would want to for example run as many DEV VMs are you can possible fit into given amount of Hosts )

    So Because only DRS is enabled , and not HA, B is the clear answer.
