Which virtualization benefit allows dividing system resources between virtual machines?

• A. Hyperthreading
• B. Partitioning
• C. Scalability
• D. Consolidation

Answer: (B)

Dividing system resources among virtual machines is achieved through partitioning. By partitioning, the hypervisor allocates portions of CPU, memory, storage, and network bandwidth to each VM, allowing multiple independent environments to run on a single physical host. This isolation ensures one VM doesn’t consume all resources and helps maintain predictable performance across machines. Dynamic partitioning can adjust allocations as workloads change, a common capability in modern hypervisors. Hyperthreading isn’t about VM resource sharing; it’s about running multiple threads on a single core. Scalability concerns handling growth, not the act of dividing resources. Consolidation aims to reduce physical hardware by running several VMs on fewer hosts, a broader outcome enabled by partitioning but not the mechanism itself.
