    Correct answer: C & F

    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.
