CNIT 242 EXAM 2 160 QUESTIONS & CORRECT
ANSWERS LATEST 2025
Virtualization - ANSWER-running multiple systems simultaneously on one physical
computer
System Virtualization - ANSWER-The process of emulating hardware so it can
be made available to multiple logical systems
True or False: Each system is independent of all others - ANSWER-True
A single computer (virtual server) appears as WHAT TYPE of computers to
multiple client or guest
operating systems? - ANSWER-independent
Traditional vs virtualized - ANSWER--Traditionally, hardware is dedicated to OS,
on which applications run
-Virtualization software emulates hardware,
which guest OSes use as if real
When did virtualization start? and why? - ANSWER-Started by IBM in the 1960s to
partition large mainframe-based systems
,When did virtualization stop? and why? - ANSWER-Abandoned in the 1980s - 90s.
Due to inexpensive x86 servers and the popularity of
client/server applications
When did virtualization pick back up? and why? - ANSWER-Virtualization support
for x86 systems was
started in 1998 by VMware to address server bloat.
Client Based (Hosted) Architecture - ANSWER-The virtualization layer is installed
on top of an existing Operating System as an application
Client Based (Hosted) Architecture typically allows the best support for what host
hardware? - ANSWER-Sound cards, USB ports, etc.
Another name for Client Based (Hosted) Architecture is... - ANSWER-Workstation
virtualization
Which architecture if more efficient...Client Based(Hosted) Architecture or Bare-
Metal(Hypervisor) Architecture? - ANSWER-Bare-Metal(Hypervisor) Architecture
True or False: Separate Operating System are required for Bare-Metal
(Hypervisor) Architecture - ANSWER-False, No separate Operating System is
necessary
Bare-Metal (Hypervisor) Architecture - ANSWER-Virtualization layer that is
installed directly on the hardware
, Virtual Machine(VM) - ANSWER-Each environment available for O/S installation
Guest Operating System - ANSWER-The operating system installed in a VM
Host Operating System - ANSWER-In a hosted architecture, the O/S in which the
virtualization software runs
Hypervisor - ANSWER-The software that provides the virtualization layer in a
bare-metal architecture
Virtualization Advantages - ANSWER--Flexibility
-Increased reliability
-Provides a consistent hardware interface regardless of the underlying physical
hardware
-Increased capacity and scalability
-Lower infrastructure costs
-Reduced energy costs
Virtualization Disadvantages - ANSWER-- Single point of failure
-Complicates hardware maintenance
-Harder to keep track of software and OSes
System Virtualization Components - ANSWER--Full Virtualization
-Paravirtualization (aka - OS Assist)
-Hardware Assisted
