Refer to the exhibit.
An environment has the following configuration:
1. Resource Pool “RP-MOM” has a reservation of 6GHz and one running virtual machine (VM) “VM-M1” with 1 GHz reserved.
2. Resource Pool “RP-KID” has a reservation of 2GHz, and expandable reservations is activated.
The administrator creates two VMs, “VM-K1” and “VM-K2”, in the “RP-KID” resource pool with 2GHz reserved for each, and turns on “VM-M1.”
Given this scenario, which statement is true?
Given the scenario, the resource pool RP-KID has a reservation of 2GHz and expandable reservations activated. This means that if the combined reservations of the virtual machines within RP-KID exceed its reservation, RP-KID can use resources from its parent resource pool RP-MOM. RP-MOM has a total reservation of 6GHz, out of which 1GHz is already reserved for VM-M1, leaving 5GHz available. VM-K2, which requires 2GHz of resources, can be powered on by borrowing the necessary resources from RP-MOM. Therefore, VM-K2 can be powered on because it can get the resources needed from RP-MOM.

Key is expandable Expandable (default) The system considers the resources available in the selected resource pool and its direct parent resource pool. If the parent resource pool also has the Expandable Reservation option selected, it can borrow resources from its parent resource pool. Borrowing resources occurs recursively from the ancestors of the current resource pool as long as the Expandable Reservation option is selected. Leaving this option selected offers more flexibility, but, at the same time provides less protection. A child resource pool owner might reserve more resources than you anticipate

When the check box is selected (default), expandable reservations are considered during admission control. If you power on a virtual machine in this resource pool, and the combined reservations of the virtual machines are larger than the reservation of the resource pool, the resource pool can use resources from its parent or ancestors.

Sorry Ans is C
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.
Based on the information provided and the search results, the correct statement is: D. VM-K2 cannot be powered on because there are not enough resources in RP-KID. This is because the "RP-KID" resource pool has a reservation of 2GHz, and both "VM-K1" and "VM-K2" have a reservation of 2GHz each, totaling 4GHz. Therefore, there are not enough resources in "RP-KID" to power on "VM-K2," and it cannot borrow resources from the parent resource pool "RP-MOM" because it has a reservation of 6GHz, and only 1GHz is currently being used by "VM-M1." 1 2 3 4 6 Option A is incorrect because deactivating expandable reservations is not necessary to turn on "VM-K2." 1 2 3 4 6 Option B is incorrect because reserving 6GHz for "VM-K3" would exceed the total reservation of 2GHz for "RP-KID." 1 2 3 4 6 Option C is incorrect because "VM-K2" cannot borrow resources from "RP-MOM" due to its reservation being higher than the current usage of "VM-M1." 1 2 3 4 6 Therefore, the correct statement is D. VM-K2 cannot be powered on because there are not enough resources in RP-KID.
