An administrator is configuring a vSphere HA cluster for three ESXi 5.x hosts and their resident
virtual machines. The cluster will be configured to support a single host failure. Resource
reservations must be enforced during a failover event.
Assuming default settings, how does HA determine the current failover capacity?

A.
Calculating the largest possible CPU and Memory guarantee for any running virtual machine in
the cluster, then calculating how many virtual machines of that size can be started on the largest
host and reserving space in the cluster accordingly.

B.
Averaging the largest possible CPU and Memory guarantee for any running virtual machine in
the cluster, then calculating how many virtual machines of that size can be started on the largest
host and reserving space in the cluster accordingly.

C.
Calculating the largest possible CPU and Memory guarantee for any virtual machine in the
cluster, then calculating how many virtual machines of that size can be started on the largest host
and reserving space in the cluster accordingly.

D.
Averaging the largest possible CPU and Memory guarantee for any virtual machine in the
cluster, then calculating how many virtual machines of that size can be started on the largest host
and reserving space in the cluster accordingly.
