When using “Cluster resource percentage” for host failover capacity in vSphere HA Admission Control, the total
resource requirements are calculated from which two values? (Choose two.)
A.
Total vCPUs assigned to each VM.
B.
Average CPU usage on each VM over time.
C.
Memory reservations on each VM.
D.
Total memory assigned to each VM.
E.
Average active memory on each VM over time.
F.
CPU reservations on each VM.

C,f
Correct: CF
A & D
This policy calculates the
amount of failover capacity to reserve by using a percentage of the total available CPU and memory resources in
the cluster. To further simplify the configuration, this percentage is now calculated automatically by defining the
number of host failures to tolerate (FTT).
Answer is C and F:
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.
