  • B. Average CPU usage on each VM over time.

Suggested Answer: CF 🗳️
vSphere HA uses the actual reservations of the virtual machines. If a virtual machine does not have reservations, meaning that the reservation is 0, a default of
0MB memory and 32MHz CPU is applied.
Computing the Current Failover Capacity
The total resource requirements for the powered-on virtual machines is comprised of two components, CPU and memory. vSphere HA calculates these values.
The CPU component by summing the CPU reservations of the powered-on virtual machines. If you have not specified a CPU reservation for a virtual machine, it is assigned a default value of 32MHz (this value can be changed using the das.vmcpuminmhz advanced option.)
The memory component by summing the memory reservation (plus memory overhead) of each powered-on virtual machine.
