Overprovisioningrefers to allocating more resources (e.g., CPU, memory) to virtual machines on a hypervisor than the physical host actually has available. This is done because not all virtual machines are likely to use their maximum resources simultaneously. Overprovisioning helps optimize resource utilization on a hypervisor but must be managed carefully to avoid performance degradation.
* Overprovisioning (Answer B):It allows for more efficient use of resources, but overcommitting too much can lead to performance issues.
* Direct access (Option A):Refers to direct hardware access, which is unrelated to resource allocation.
* Link aggregation (Option C):Refers to combining multiple network connections, unrelated to hypervisor resources.
* Component redundancy (Option D):Refers to using backup components for fault tolerance, not related to overprovisioning.
* Scalability (Option E):Refers to the ability to increase or decrease resources as needed but doesn't describe overcommitting resources.
