The correct answer is D. all of the mentioned.
A Type 1 hypervisor is a hypervisor that runs directly on the hardware of the host machine. It is also known as a bare-metal hypervisor. A Type 2 hypervisor is a hypervisor that runs on top of an operating system. It is also known as a hosted hypervisor.
Full virtualization is a virtualization technique that allows multiple operating systems to run on the same physical hardware at the same time. It is achieved by creating a virtual machine (VM) for each operating system. The VM is a software-based emulation of a physical machine, including its hardware, such as the CPU, memory, storage, and network interface.
The benefits of full virtualization include:
- Increased resource utilization: Multiple operating systems can share the resources of a single physical machine, which can lead to increased resource utilization.
- Improved security: Each VM is isolated from the others, which can help to improve security.
- Increased flexibility: VMs can be easily created, destroyed, and moved, which can provide increased flexibility.
The drawbacks of full virtualization include:
- Performance overhead: The hypervisor adds some overhead to the system, which can impact performance.
- Complexity: Full virtualization can be more complex to manage than other virtualization techniques.
- Compatibility: Not all operating systems are compatible with full virtualization.
Overall, full virtualization is a powerful virtualization technique that offers a number of benefits. However, it is important to be aware of the potential drawbacks before implementing it.
