Which type of Hyper-V switch allows virtual machines to communicate with the external network?

1. Private

2. Internal

3. External

4. Local

The correct answer is: External

The type of Hyper-V switch that allows virtual machines (VMs) to communicate with the external network is the external switch. An external virtual switch connects the VMs to the physical network adapter of the host machine, enabling them to access external networks, including the internet and other resources outside the host. When an external switch is configured, it effectively bridges the VMs and the external network, allowing for full connectivity, including the ability to communicate with servers and devices beyond the host system. This setup is essential for scenarios where VMs need to engage directly with services, perform updates, or interact with users on an external network. The other switch types serve different purposes: the private switch allows communication solely between VMs on the same host without any external connectivity; the internal switch enables communication between VMs and the host machine but not with external networks; and the local switch is not a recognized type in Hyper-V standards, which further clarifies that the external switch is the only option for providing external network access.
