What is ESXi?

• A. Bare-metal type 1 hypervisor
• B. Hosted hypervisor
• C. Operating system
• D. Network switch

Answer: (A)

ESXi is a bare-metal hypervisor that runs directly on server hardware, forming the virtualization layer that hosts virtual machines without needing a separate operating system. Because it sits directly on the hardware, it controls the physical resources (CPU, memory, storage, networking) and provides VMs with direct access to them, which gives high performance and efficient resource use. This distinguishes it from hosted hypervisors, which operate inside a general-purpose operating system and rely on that host OS for drivers and resources. It’s not an ordinary operating system for everyday computing, and it isn’t a network switch. In short, ESXi is a bare-metal Type 1 hypervisor.
