E.

Scalability

Answers
E.

Scalability

Suggested answer: B

Explanation:

Overprovisioning refers 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.
