Why each option
A DNS server deployed within a virtual environment runs inside a virtual machine, making it a guest operating system.
The Host OS is the operating system running directly on the physical hardware that hosts the hypervisor and virtual machines.
In a virtual environment, a server like a DNS server is typically deployed as a virtual machine, which runs its own operating system known as a guest operating system, isolated from the underlying host.
A proxy server is a type of network server that acts as an intermediary for requests from clients seeking resources from other servers, not a descriptor of a server's operating environment.
A hypervisor is the software layer that creates and runs virtual machines, not a virtual machine itself.
