Which of the following is a benefit of having a virtual versus physical server environment?

Virtualization does not inherently improve security - VMs share the same hypervisor and physical hardware, and a compromised hypervisor can expose all hosted VMs.

IPSec is a network-layer encryption protocol used for secure tunnels and is not a benefit unique to or resulting from server virtualization.

Data scraping is a technique for extracting data from websites or systems and has no direct relationship to the benefits of virtualization.

Virtualization enables redundancy through features such as live migration, high availability clustering, and VM snapshots that allow workloads to be moved or recovered across physical hosts seamlessly. Physical servers require duplicate hardware to achieve similar redundancy, making virtualization a cost-effective way to eliminate single points of failure. This is one of the primary business drivers for adopting a virtual server environment.
