E.
Scalability
Suggested answer: B

Explanation:

Overprovisioning:Involves allocating more virtual resources (e.g., CPU, RAM, storage) to virtual machines than the total physical resources available on a hypervisor. The idea is for resources to be dynamically shared, assuming not all VMs will demand their maximum allocation simultaneously.

Direct Access:This usually refers to technologies like RDMA (Remote Direct Memory Access) that allow for very low-latency, direct access to the memory of another computer over a network.

Link Aggregation:The practice of combining multiple physical network links to create a single logical link with increased bandwidth.

Component Redundancy:Refers to having multiple hardware components (e.g., power supplies, hard drives) to provide fault tolerance.

Scalability:The ability of a system to adapt and handle increased workloads by adding resources.

References:

CompTIA Server+ Objectives(Exam codes SK0-004 or SK0-005): Review the sections on virtualization concepts.

Virtualization Technology Documentation:Refer to documentation for popular hypervisors like VMware vSphere, Microsoft Hyper-V, or open-source solutions.
