A company has asked their network engineer to list the major advantages for implementing a virtual environment in regards to cost. Which of the following would MOST likely be selected?

Ease of patch testing is an operational and risk-reduction benefit but does not directly translate into reduced financial costs.

Reducing physical footprint is the most direct cost benefit of virtualization because fewer physical servers are required to run the same number of workloads. This consolidation lowers capital expenditure on hardware, reduces power consumption, decreases cooling requirements, and minimizes data center floor space costs. All of these translate into measurable, ongoing financial savings that are the primary business justification for virtualization adoption.

Virtualization does not inherently reduce network traffic; virtual machines still generate the same application-level traffic as physical hosts.

Application isolation is a security and availability benefit, not a cost-reduction benefit of virtualization.
