SK0-004 · Question #5
Which of the following is a benefit of utilizing a type 2 hypervisor to manage guests?
The correct answer is D. There is increased hardware support since there is an OS layer. A type 2 hypervisor runs on top of an existing host OS, which provides access to all hardware drivers and device support that the host OS already includes.

Why each option
A type 2 hypervisor runs on top of an existing host OS, which provides access to all hardware drivers and device support that the host OS already includes.
Guest OS administration complexity is not reduced by the hypervisor type - managing guest OSes requires the same effort regardless of whether a type 1 or type 2 hypervisor is used.
This describes a benefit of type 1 hypervisors, not type 2 - type 2 actually introduces additional resource overhead because it runs on top of a host OS that itself consumes CPU, memory, and storage.
Type 2 hypervisors generally offer lower performance than type 1 because every guest OS operation must pass through the host OS layer, adding latency and overhead.
Because a type 2 hypervisor sits on top of a host operating system, it inherits the full hardware driver ecosystem of that OS, giving it broad compatibility with diverse hardware without needing custom drivers. This is a primary advantage over type 1 hypervisors, which must include their own hardware drivers. The host OS acts as an abstraction layer that expands the range of supported devices.
