A VMware administrator determines that the active memory on an ESXi 5.x host is 20% and the consumed memory is 90%.
How much host memory is available to virtual machines?
A. 80%
B. 10%
C. 70%
D. 20%
Correct Answer: A
Explanation/Reference:
Explanation:
A: Consumed memory = total host memory – free host memory. Thus consumed memory consists of virtual machine consumed memory and overhead memory. It does not include host-specific overhead memory, such as memory used by the service console or VMkernel. It is mentioned in the question that the active memory on the host is 20 % – thus the host memory available to virtual machines will be 100% – 20 % = 80%.
Incorrect Answers:
B: 90% is the consumed memory and not the host’s memory.
C: Consumed memory – the active memory is not the host’s active memory that is available to virtual machines.
D: 20% is mentioned as the active memory of the hosts, it is not the total host memory available to virtual machines.
