    Question

    Which of the following accurately describes Type 1

    hypervisor virtualization? 
    A Runs directly on the host hardware and does not require an operating system. Correct Answer Incorrect Answer
    B Requires a host operating system to run virtual machines. Correct Answer Incorrect Answer
    C Is generally slower than Type 2 virtualization. Correct Answer Incorrect Answer
    D Supports only Windows operating systems. Correct Answer Incorrect Answer
    E Can only run one virtual machine at a time. Correct Answer Incorrect Answer

    Solution

    Type 1 hypervisor virtualization, also known as bare-metal virtualization, runs directly on the physical host hardware without the need for a host operating system. This architecture allows for better performance and efficiency since the hypervisor has direct access to the hardware resources, enabling it to allocate resources to virtual machines (VMs) more effectively. Type 1 hypervisors, such as VMware vSphere/ESXi, Microsoft Hyper-V, and Xen, are commonly used in enterprise environments for their robustness, scalability, and ability to support multiple VMs simultaneously. Since they operate without a host OS layer, Type 1 hypervisors typically offer improved performance, enhanced security, and better resource management compared to Type 2 hypervisors, which run on top of a host OS. Option B (Requires a host operating system to run virtual machines) - This description is applicable to Type 2 hypervisors, which operate on a host OS, thus incurring additional overhead. Option C (Is generally slower than Type 2 virtualization) - Type 1 hypervisors are usually faster than Type 2 hypervisors because they interact directly with the hardware, reducing latency. Option D (Supports only Windows operating systems) - Type 1 hypervisors can support multiple operating systems, including various distributions of Linux and Unix, in addition to Windows. Option E (Can only run one virtual machine at a time) - Type 1 hypervisors can run multiple VMs concurrently, utilizing the underlying hardware resources effectively.
