2V0-622 · Question #192

Refer to the Exhibit. A vSphere 6.x DRS cluster is configured as shown in the Exhibit. Based on the exhibit, which statement is true?

The correct answer is C. A virtual machine can be powered on in the DB Resource Pool with a 3 GHz CPU Reservation.. DRS resource pool admission control prevents a VM from powering on if its requested CPU reservation exceeds the pool's remaining available capacity.

Why each option

DRS resource pool admission control prevents a VM from powering on if its requested CPU reservation exceeds the pool's remaining available capacity.

AA virtual machine can be powered on in the Web Resource Pool with a 3 GHz CPU Reservation.

The Web Resource Pool does not have enough remaining CPU capacity to satisfy a 3 GHz reservation according to the limits and current allocations shown in the exhibit.

BA virtual machine can be powered on in the Web Resource Pool with a 4 GHz CPU Reservation.

The Web Resource Pool cannot accommodate a 4 GHz reservation because its configured CPU limit or available capacity is too low per the exhibit's configuration.

CA virtual machine can be powered on in the DB Resource Pool with a 3 GHz CPU Reservation.Correct

Based on the exhibit's resource pool configuration, the DB Resource Pool has sufficient unreserved CPU capacity to satisfy a 3 GHz reservation. Admission control checks that the sum of all child VM reservations plus the new request does not exceed the pool's configured CPU limit or expandable reservation before permitting the power-on operation.

DA virtual machine can be powered on in the DB Resource Pool with a 4 GHz CPU Reservation.

The DB Resource Pool cannot satisfy a 4 GHz reservation because that amount exceeds the pool's remaining available CPU allocation as shown in the exhibit.
