What is the most common type of virtualization, partitioning the physical server into smaller virtual servers?

• A. Server
• B. Storage
• C. Application
• D. Network

Answer: (A)

Partitioning a physical server into smaller virtual servers is server virtualization. A hypervisor sits between the hardware and the virtual machines, letting one physical machine host several independent VMs, each with its own operating system, memory, CPU, and storage. This enables hardware consolidation, workload isolation, and easier provisioning and management. The most common form uses bare-metal hypervisors such as VMware ESXi, Microsoft Hyper-V, or KVM, which run directly on the hardware for strong performance. Other forms—storage virtualization, application virtualization, and network virtualization—focus on abstracting or pooling other resources rather than creating separate full servers. The core idea here is creating multiple independent virtual servers from a single physical machine.
