Which of the following statements is false about virtual system resource allocation?

Virtual systems can share and preempt resources of the entire device. Such resources can be manually allocated.

To manually allocate resources to a virtual system, an administrator needs to configure a resource class, specify the guaranteed quota and maximum quota of each resource in the resource class, and bind the resource class to the virtual system.

Improper resource allocation may prevent other virtual systems from obtaining resources and services from running properly.

Quota-based resources are automatically allocated based on system specifications.
