The administrator wants to power on VM-K2, which has a 2GHz CPU reservation. VM-M1, VM-M2, and VM-K1
are all powered on. VM-K2 is not powered on.
The exhibit shows the parent and child resource reservations.
If Resource Pool RP-KID is configured with an expandable reservation, which statement is true?
A.
VM-K2 will be unable to power on because there are insufficient resources.
B.
VM-K2 will be able to power on since resource pool RP-KID has 2GHz available.
C.
VM-K2 will be unable to power on because only 2GHz are reserved for RP-KID.
D.
VM-K2 will receive resource priority and will be able to power on this scenario.

No local resources are available for VM-K2, so it borrows resources from the parent resource pool, RP-MOM. RP-MOM has 6GHz minus 1GHz (reserved by the virtual machine) minus 2GHz (reserved by RP-KID), which leaves 3GHz unreserved. With 3GHz available, you can power on the 2GHz virtual machine.
Power on two virtual machines in RP-MOM with a total reservation of 3GHz.
You can still power on VM-K1 in RP-KID because 2GHz are available locally.
When you try to power on VM-K2, RP-KID has no unreserved CPU capacity so it checks its parent. RP-MOM has only 1GHz of unreserved capacity available (5GHz of RP-MOM are already in use—3GHz reserved by the local virtual machines and 2GHz reserved by RP-KID). As a result, you cannot power on VM-K2, which requires a 2GHz reservation.
