Which description of virtualization is correct?

Virtualization allows for multiple virtual machines to run on a single physical host, providing the ability to create an efficient use of hardware resources. The correct description indicates that virtualization and non-virtualization can indeed coexist within the same data center. This means that an organization can run both virtual machines and physical servers side by side, leveraging the benefits of virtualization—such as better resource utilization, ease of management, and scalability—while still maintaining certain applications or workloads on dedicated physical hardware when necessary.

This coexistence is fundamental to many data centers, as it allows for a strategic approach where businesses can migrate to virtual environments gradually, test new technologies without disrupting existing operations, and retain legacy systems that may not be compatible with virtualization.
