Which of the following technologies would be MOST appropriate to utilize when testing a new software patch
before a company-wide deployment?

A.
Cloud computing

B.
Virtualization

C.
Redundancy

D.
Application control

Explanation:
Virtualization is used to host one or more operating systems in the memory of a single host computer and
allows multiple operating systems to run simultaneously on the same hardware, reducing costs. Virtualization
offers the flexibility of quickly and easily making backups of entire virtual systems, and quickly recovering the
virtual system when errors occur. Furthermore, malicious code compromises of virtual systems rarely affect the
host system, which allows for safer testing and experimentation.References:
