An administrator wants to leverage more usage out of their server resources. Which of the following virtualization technologies would BEST accomplish this?

Server virtualization enables consolidation of multiple logical servers onto a single physical hardware platform, which directly maximizes the usage of CPU, memory, and I/O resources on that physical server. This technology creates a virtual machine abstraction layer, making the underlying hardware appear as multiple independent servers.

Application virtualization isolates applications from the underlying operating system and other applications, primarily for deployment and compatibility, not direct server resource consolidation.

Storage virtualization pools storage resources from multiple physical storage devices into a single virtual storage resource, enhancing management and flexibility, but not directly leveraging server computing resources.

Para-virtualization is a virtualization technique that optimizes guest OS performance by modifying it to communicate with the hypervisor, but it is a type of server virtualization, not the overarching technology for resource leveraging.
