What is Hyper-V, and what does a virtual switch do?

• A. Hyper-V is the Windows Server virtualization role; a virtual switch connects virtual machines to each other and to the physical network.
• B. Hyper-V is a file-sharing service.
• C. A virtual switch stores virtual disks.
• D. Hyper-V is a remote access gateway.

Answer: (A)

Hyper-V is a Windows Server virtualization feature that provides a hypervisor to run multiple guest operating systems on a single physical server. A virtual switch inside Hyper-V is a software-based network switch that connects the virtual machines to each other and to the physical network, enabling real network communication for those VMs. This switch can be configured in different modes: external to give VMs access to the physical network through a host NIC, internal to let VMs communicate with the host and other VMs but not out to the physical network, or private to isolate VMs from the host and from external networks entirely. The combination of Hyper-V and a virtual switch is what powers VM networking, not file sharing, disk storage, or remote access gateway functions.
