Which of the following descriptions about virtual system resource allocation is incorrect?

Question

Options

• AUnreasonable resource allocation may cause other virtual systems to be unable to obtain
• BQuota resources automatically allocate a fixed number of resources directly according to system
• CWhen the administrator manually allocates resources to the virtual system, he first needs to
• DEach virtual system can share and seize the entire machine resources, but they can be allocated

• A
  10% (2)
• B
  14% (3)
• C
  5% (1)
• D
  71% (15)

Explanation

Option D is incorrect because virtual systems do not have the ability to freely "seize" the entire machine's resources - they operate within boundaries defined by the hypervisor or administrator. The defining principle of virtualization is controlled resource sharing, not unconstrained competition; one virtual system cannot arbitrarily take resources away from another.

Why the distractors are correct (and thus not the answer):

• A is a true statement - poor resource planning can starve other virtual systems, making it a real concern administrators must manage.
• B is true - quota-based allocation reserves a fixed, predetermined amount of resources for a virtual system automatically.
• C is true - manual resource allocation requires prerequisite steps (such as confirming available capacity) before assigning resources.

Memory tip: Think of virtual systems as apartment tenants sharing a building's utilities. Tenants share the pool (the machine's resources), but no single tenant can "seize" the whole building's power. The landlord (hypervisor/admin) enforces limits - so any statement claiming a VM can freely take all machine resources should immediately signal "incorrect."
