CNIT 242 - Exam 2 Questions with Correct Answers (Grade A+)
Question 1: What is virtualization?
Answer: Virtualization refers to the creation of a virtual representation or simulation of a resource or
system, allowing for efficient utilization and management of IT resources.
Question 2: Give examples of the term "virtual" in IT.
Answer: Virtual memory (simulated memory space for enhanced performance) Virtual drives (simulated
storage devices within physical storage) Virtual CD-ROMs (simulated optical drives to access disk images)
Question 3: How is spoofing or faking related to virtualization?
Answer: Anything that is spoofed or faked in the digital realm, imitating a different hardware or software
environment, is considered virtualization.
Question 4: What does the term "system or server virtualization" signify in modern usage?
Answer: "System or server virtualization" primarily refers to creating virtual instances or representations of
entire systems or servers to optimize resource usage and management.
Question 5: What is system virtualization?
Answer: System virtualization is the process of emulating hardware, making it available to multiple logical
systems. It allows the simultaneous running of multiple operating systems on a single computer, each
operating system being independent of the others.
Question 6: What does system virtualization enable?
Answer: System virtualization enables the ability to run multiple operating systems simultaneously on a
single computer. Each operating system operates independently, as if it were running on its own dedicated
hardware.
Question 7: How does a single computer appear in system virtualization?
Answer: In system virtualization, a single computer, often referred to as a virtual server, appears as
independent computers to multiple client or guest operating systems.

,Question 8: How is hardware allocated in traditional setups?
Answer: In traditional setups, hardware is dedicated to the operating system (OS) on which applications run.
Question 9: What is the role of virtualization software in the context of hardware emulation?
Answer: Virtualization software emulates hardware, providing a virtual representation that guest operating
systems use as if it were real hardware.
Question 10: When did IBM start virtualization and why?
Answer: IBM initiated virtualization in the 1960s to partition large mainframe-based systems with VM/370.
Question 11: Why did virtualization decline in the 1980s-90s?
Answer: Due to inexpensive x86 servers and client/server application popularity, traditional virtualization
declined.
Question 12: When did x86 virtualization support begin, and by whom?
Answer: VMware pioneered x86 virtualization support in 1998 to combat server inefficiencies and high
costs.
Question 13: What is Client Based (Hosted) Architecture in system virtualization?
Answer: Client Based (Hosted) Architecture involves installing the virtualization layer on top of an existing
Operating System.

, Question 14: What advantages does Client Based (Hosted) Architecture offer in system virtualization?
Answer: Client Based (Hosted) Architecture allows other programs to run alongside the virtualization
software.
Question 15: What is another term for Client-Based Architecture in system virtualization?
Answer: Workstation virtualization
Question 16: What advantage does Client-Based Architecture typically offer concerning host
hardware?
Answer: It typically allows the best support for host hardware, including sound cards, USB ports, and other
peripherals.
Question 17: What does Bare-Metal (Hypervisor) Architecture entail in system virtualization?
Answer: Bare-Metal Architecture involves installing the virtualization layer directly on the hardware,
without the need for a separate Operating System.
Question 18: How does Bare-Metal Architecture manage system resources and user interfaces?
Answer: It typically offers a small console for management, making it more efficient than hosted
architectures.
Question 19: What is the primary advantage of Bare-Metal Architecture compared to Client-Based
Architecture?
Answer: Bare-Metal Architecture is generally more efficient because it eliminates the need for an
underlying host Operating System, allowing for better resource utilization.
Question 20: What is a Virtual Machine (VM) in the context of virtualization?
Answer: A Virtual Machine (VM) represents each environment available for Operating System (OS)
installation.
Question 21: How would you define a Virtual Machine (VM) in simple terms?
Answer: A Virtual Machine (VM) is like a digital computer within a physical computer, enabling the
installation of an operating system and running applications.
Question 22: What does the term "Guest Operating System" refer to in virtualization?
Answer: The Guest Operating System is the operating system installed and running within a Virtual
Machine (VM).
