    Which action is required when creating a virtual machine (VM) from a basic template that is not required when creating a VM from a full template?

    • Using the vendor installer

    • Configuring a new system identity

    • Updating the MAC address manually

    • Exporting the template before using it

    Correct Answer
    A. Using the vendor installer
    Explanation
    When creating a virtual machine (VM) from a basic template, using the vendor installer is required. This is because a basic template only includes the bare minimum software and configurations, so the vendor installer is needed to install the necessary operating system and other software. On the other hand, when creating a VM from a full template, the template already includes the operating system and software, so using the vendor installer is not required.

    What is the function of full emulation?

    • Simulating the complete hardware

    • Running applications as conventional local software

    • Leveraging a hypervisor for the underlying technology

    • Offering an API that modifies the guest operating system

    Correct Answer
    A. Simulating the complete hardware
    Explanation
    Full emulation refers to the process of simulating the complete hardware of a computer system. This means that the software is designed to mimic all the components and functionalities of the actual physical hardware. Full emulation is commonly used in virtualization technology, where it allows a virtual machine to run on a host system, replicating the behavior of a physical computer. This enables the virtual machine to run different operating systems and applications as if they were running on a real computer, providing a high level of compatibility and flexibility.

    Which two components are automatically installed in a newly built Windows virtual machine (VM)? (Choose two.)

    • XenSource Tools

    • Emulated NIC drivers

    • Paravirtualized drivers

    • Emulated IDE disk drivers

    Correct Answer(s)
    A. Emulated NIC drivers
    A. Emulated IDE disk drivers
    Explanation
    In a newly built Windows virtual machine (VM), two components that are automatically installed are emulated NIC drivers and emulated IDE disk drivers. Emulated NIC drivers allow the VM to communicate with the network by emulating a network interface card. Emulated IDE disk drivers enable the VM to access and use emulated IDE disks for storage purposes. These drivers are automatically installed to ensure proper functionality and connectivity within the virtual machine environment.

    Which two subsystems incur performance penalties if a Windows virtual machine (VM) runs with the emulated drivers rather than with the paravirtualized drivers? (Choose two.)

    • Display

    • Storage

    • Memory

    • Network

    • Processor

    Correct Answer(s)
    A. Storage
    A. Network
    Explanation
    The storage and network subsystems incur performance penalties if a Windows virtual machine (VM) runs with emulated drivers instead of paravirtualized drivers. Emulated drivers are software-based and require more processing power, resulting in slower disk and network I/O operations. Paravirtualized drivers, on the other hand, are optimized for virtual environments and provide direct access to the underlying hardware, improving performance for storage and network operations.

    What is a characteristic of paravirtualization?

    • The complete hardware is simulated.

    • The physical server is virtualized at the operating system level.

    • The desktop or server applications run locally using local resources.

    • The guest operating systems are aware they are running in a virtualized environment.

    Correct Answer
    A. The guest operating systems are aware they are running in a virtualized environment.
    Explanation
    Paravirtualization is a virtualization technique where the guest operating systems are aware that they are running in a virtualized environment. This means that the guest operating systems have been modified to work in cooperation with the hypervisor, allowing for improved performance and efficiency. In paravirtualization, the hypervisor provides an interface for the guest operating systems to communicate and interact with the underlying hardware. This awareness of the virtualized environment allows for better resource management and optimization, resulting in improved performance for the virtual machines.
