What does virtualization enable regarding applications and servers?

Virtualization is a technology that allows multiple operating systems and applications to run on a single physical server. It creates a virtual environment where "guest applications" can operate independently from each other and from the underlying hardware. This capability enables efficient resource management, as multiple virtualized servers can share the same physical hardware, leading to better utilization and reduced costs.

By running guest applications on a virtual server, organizations can achieve flexibility and scalability. Virtualization also simplifies the deployment of applications, improves disaster recovery processes, and facilitates easier management of system resources. This is particularly advantageous in dynamic environments where workload demands can fluctuate, allowing for quick adjustments and the ability to easily create, scale, or clone virtual machines as needed.

The other options do not accurately describe the primary capabilities of virtualization. Storing applications on physical servers pertains to traditional server setups without the benefits of virtualization. Transferring applications to a different network does not capture the essence of what virtualization provides. Blocking applications from accessing the Internet is more related to security policies and firewall functions, rather than the virtualization of servers and applications.
