What is ESXi?

• A. Bare-Metal Type 1 Hypervisor
• B. Linux-based Type 2 Hypervisor
• C. Container runtime
• D. Network switch

Answer: (A)

The concept being tested is how virtualization software is structured on a server. ESXi is a bare-metal Type 1 hypervisor, meaning it installs directly on the physical hardware rather than on top of another operating system. It manages all hardware access and runs multiple virtual machines on the server, without requiring a host OS. This direct-to-hardware approach provides efficient resource use and strong isolation between VMs. In contrast, a Type 2 hypervisor runs as an application on an existing operating system, which adds layers of overhead and dependency on that host OS. A container runtime is focused on running containers rather than full virtual machines, so it’s a different virtualization paradigm. A network switch is unrelated to the virtualization software category in question.
