What benefit does virtualization provide to an enterprise?

1. It eliminates the need for physical servers

2. It reduces costs while allowing multiple OSs to coexist

3. It automatically manages software updates

4. It prevents unauthorized access to resources

The correct answer is: It reduces costs while allowing multiple OSs to coexist

The correct choice highlights a fundamental advantage of virtualization, which is its ability to reduce costs while allowing multiple operating systems to coexist on a single physical machine. This is achieved through the use of hypervisors, which abstract the hardware resources and allocate them dynamically based on demand. By enabling multiple virtual machines (VMs) to run on a single physical server, enterprises can maximize hardware utilization, reduce the number of physical servers needed, and therefore cut down on capital expenditures such as hardware purchases and ongoing operational costs like power, cooling, and maintenance. The coexistence of multiple operating systems can also facilitate development, testing, and deployment of applications in diverse environments without the need for numerous physical devices, increasing efficiency and flexibility. Optimizing resource usage also means that enterprises can respond more swiftly to changing demand without over-provisioning or under-utilizing their IT resources. This capacity to rapidly adapt supports better service delivery and performance overall. The other choices do not accurately reflect the primary benefits of virtualization. While it can lead to fewer physical servers, it does not entirely eliminate the need for them. Additionally, while virtualization can aid in software management, it does not automatically manage software updates. Lastly, while security measures may be enhanced with virtualization technologies, preventing unauthorized access primarily
