An Administrator is configuring a VMware HA Cluster for three hosts and their resident
VMs. The HA cluster will be configured to support a single host failure and resource
considerations must be enforced during a failover event. To accomplish this task?

A.
There must be enough cluster resources based on memory and CPU reservations to
account for any potential host failure

B.
All potential remaining hosts during a failure event must be able to accommodate the
sum total of all VM memory configurations

C.
Each host in the cluster must be able to accommodate the VM with the largest
configured available memory

D.
Each host in the cluster must be able to accommodate the VM with the highest CPU
limit value

VMware HA provides high availability for virtual machines by pooling them and the
hosts they reside on into a cluster. Hosts in the cluster are monitored and in the event of a
failure, the virtual machines on a failed host are restarted on alternate hosts. Therefore
there should be sufficient capacity to support any single host failover, (A)
