What type of Hyper-V virtual switch allows communication only between VMs on the same host?

1. External

2. Internal

3. Private

4. Public

The correct answer is: Private

The correct choice is that a private virtual switch in Hyper-V allows communication only between virtual machines that are hosted on the same physical system. With a private switch, virtual machines cannot communicate with the host machine or with any external networks. This isolation is particularly useful in a testing or development environment where you want to ensure that the virtual machines can interact with each other without any outside access or interference. In the context of the other types of switches: An external virtual switch allows VMs to communicate both with each other and with external networks, including the host machine, thus giving them access to the internet or other network resources. An internal virtual switch allows VMs to communicate with each other and with the host, which is broader than the restricted communication of a private switch. The term public generally does not apply to Hyper-V virtual switches; the appropriate terminology would be external, internal, or private, as mentioned. Understanding this distinction is crucial for network configuration and security in a Hyper-V environment, ensuring that the VMs are set up according to the desired level of connectivity and isolation.
