2V0-620 · Question #128
An administrator is moving a virtual machine into a resource pool. The VM and resource pool are configured as shown: VM configuration: 2GHz CPU reservation 1GB Memory limit Resource Pool configuration
The correct answer is D. The VM keeps the 2GHz CPU reservation and the 1GB Memory limit.. When a VM is moved into a resource pool, it retains its own individually configured reservations and limits rather than inheriting or being overridden by the pool's settings.
Question
An administrator is moving a virtual machine into a resource pool. The VM and resource pool are configured as shown:
VM configuration:
2GHz CPU reservation 1GB Memory limit Resource Pool configuration:
6GHz CPU reservation 1GB Memory reservation No limit to memory What happens to the virtual machine's resource settings when it is moved into the pool?
Options
- AThe VM inherits the resource settings of the resource pool if expandable reservations is enabled.
- BThe VM's reservations and limits are ignored and removed.
- CThe VM keeps the 2GHz CPU reservation but receives the 1GB memory reservation.
- DThe VM keeps the 2GHz CPU reservation and the 1GB Memory limit.

Why each option
When a VM is moved into a resource pool, it retains its own individually configured reservations and limits rather than inheriting or being overridden by the pool's settings.
Expandable reservations control whether a resource pool can borrow resources from its parent pool to satisfy child reservations; it does not cause VMs to inherit the pool's settings.
Moving a VM into a resource pool does not strip or remove its configured reservations and limits; those settings are preserved as part of the VM's configuration.
The VM does not receive the pool's 1 GB memory reservation - it retains its own 1 GB memory limit, which is a ceiling on consumption rather than a guaranteed allocation, and these two concepts are not interchangeable.
A VM's resource settings - reservations, limits, and shares - are VM-level properties that persist when the VM is relocated into a resource pool. The VM keeps its 2 GHz CPU reservation and its 1 GB memory limit because these are independent of the pool's own reservation and limit configuration. The pool's resources define the aggregate budget available to all its children, but do not replace individual VM settings.
