1V0-21.20 · Question #107
Which two challenges could be resolved by Implementing Data Center Virtualization? (Choose two.)
The correct answer is A. An organization's physical server Infrastructure Is approaching 90% utilization. D. The IT department spends significant budget on power and cooling requirements. Data Center Virtualization resolves challenges related to inefficient hardware utilization by allowing consolidation, and reduces operational costs associated with power and cooling by decreasing the physical server footprint.

Why each option
Data Center Virtualization resolves challenges related to inefficient hardware utilization by allowing consolidation, and reduces operational costs associated with power and cooling by decreasing the physical server footprint.
If physical servers are approaching 90% utilization, virtualization can consolidate multiple underutilized servers onto fewer physical hosts, or provide more flexible resource allocation to prevent individual servers from becoming overloaded, improving efficiency.
An average utilization of 30% indicates underutilization, which virtualization helps to solve by consolidating workloads, making it an opportunity for virtualization, not a problem that virtualization resolves in this context.
While virtualization can introduce complexities that impact storage performance if not properly designed, it does not inherently resolve slow storage performance, which is often a separate underlying infrastructure component issue.
Virtualization enables server consolidation, which reduces the total number of physical servers required in a data center, directly leading to lower power consumption and cooling demands and thus reducing operational expenses.
