Which two events occur during an ESXi host failure?

An administrator is configuring admission control settings for a vSphere HA cluster. The administrator selects the option Allow VMs to be powered ON even they violate availability constraints.

Which two events occur during an ESXi host failure? Choose two

only virtual machines with a high restart priority are restarted on surviving ESXi hosts

vSphere HA cannot guarantee that all virtual machines from a failed host will be restarted

vSphere HA restarts virtual machines on surviving ESXi hosts with the most unreserved capacity

virtual machines can be powered on until the percentage of cluster resources reaches 25 percent

    I think that should be B, C. Scott Lowe says in his vSphere 5 book “If there is an ESXi host failure … it’s possible that some of the VMs would not be able to be restarted …” (p 379)

  2. Kahlan says:

    I agree with dsloyer.
    Per vsphere 5 high availability guide:
    “If cluster has insufficient failover capacity, vsphere HA can still perform failovers as it uses the VM Restart Priority setting to determine which virtual machine to power on first.”

    aka: If will follow the order down until it has reached capacity. It will not be limited to high priority only
