    What is a primary advantage of using virtual machines in

    a computing environment? 
    A They increase the physical hardware requirements of the system. Correct Answer Incorrect Answer
    B They allow multiple operating systems to run simultaneously on a single physical machine. Correct Answer Incorrect Answer
    C They provide a more complex environment for application deployment. Correct Answer Incorrect Answer
    D They require less maintenance than traditional hardware systems. Correct Answer Incorrect Answer
    E They eliminate the need for resource allocation strategies. Correct Answer Incorrect Answer

    Solution

    Virtual machines (VMs) provide a powerful abstraction layer that allows multiple operating systems to run concurrently on a single physical host. This capability is particularly beneficial in environments where different applications may require different operating systems or configurations. By encapsulating the entire operating system and its applications within a VM, organizations can maximize hardware utilization while maintaining isolation between environments, thus enhancing security and stability. Virtualization allows for efficient resource management, as VMs can be provisioned, scaled, and migrated across physical servers without significant downtime. Additionally, virtual machines facilitate development and testing processes by enabling developers to create isolated environments for application deployment, thus reducing conflicts and simplifying version control. This flexibility not only improves operational efficiency but also reduces overall hardware costs, making virtual machines a cornerstone of modern IT infrastructure. Option A (Increase hardware requirements) - Virtual machines do not increase physical hardware requirements; they allow better utilization of existing hardware resources. Option C (More complex environment) - While VMs can introduce complexity, their primary advantage lies in enabling multiple environments rather than complicating deployment. Option D (Less maintenance) - VMs require maintenance, but this is more about managing virtual resources rather than reducing maintenance needs compared to physical systems. Option E (Eliminate resource allocation strategies) - Virtual machines still require effective resource allocation and management strategies to ensure optimal performance and resource usage.
