Which of the following BEST describes server virtualization?
Click on the arrows to vote for the correct answer
A. B. C. D.D.
Server virtualization is a technology that allows multiple virtual servers to run on a single physical server. This technology enables the creation of multiple virtual machines (VMs) that operate independently and can run multiple operating systems, applications, and workloads on a single physical server.
The best description of server virtualization among the provided options is D. Multiple logical servers operating on the same physical server. This is because virtualization creates logical servers, which are independent and isolated instances of operating systems and applications, running on a single physical server.
In this scenario, each virtual server has its own resources, such as CPU, memory, storage, and network, which are allocated from the physical server's resources. The virtualization layer abstracts the underlying hardware from the virtual servers, providing flexibility, scalability, and improved resource utilization.
Option A, a single logical server operating on multiple physical servers, is incorrect because virtualization creates multiple logical servers on a single physical server. Option B, applications hosted on a single server and deployed to multiple users, is incorrect because it does not relate to virtualization, but rather to application deployment. Option C, multiple servers used to host applications for multiple users, is also incorrect because it does not describe server virtualization, but rather a traditional server infrastructure.
