Questions and Answers

What is the primary function of a hypervisor?

To provide a platform for running applications without an OS.
To act as a firewall between virtual machines.
To manage physical server hardware directly without virtualization.
To virtualize physical hardware components for use by virtual machines. (correct)

Which characteristic primarily distinguishes a Type 1 hypervisor from a Type 2 hypervisor?

Type 1 hypervisors are typically used in development environments, while Type 2 hypervisors are for production.
Type 1 hypervisors are installed on top of an existing OS, while Type 2 hypervisors run directly on hardware.
Type 1 hypervisors have lower performance than Type 2 hypervisors.
Type 1 hypervisors run directly on the hardware, while Type 2 hypervisors require an underlying OS. (correct)

Why do Type 1 hypervisors generally offer higher performance compared to Type 2 hypervisors?

Type 1 hypervisors use more efficient virtualization techniques.
Type 1 hypervisors operate closer to the hardware without the overhead of an OS. (correct)
Type 1 hypervisors have access to a wider range of hardware drivers.
Type 1 hypervisors always have more dedicated resources allocated to them.

Flashcards

Hypervisor

Software that virtualizes computer hardware, managing interactions between the host machine's hardware and the virtual machines.

Type 1 Hypervisor

Implemented directly on the physical hardware without needing an OS.
