IT 306 Virtualization
Comprehensive Final Exam (Qns & Ans)
2025
Question 1 (Multiple Choice)
Question:
Which type of hypervisor is deployed directly on server hardware
without relying on an underlying host operating system?
A) Type 2 hypervisor
B) Paravirtualizer
C) Type 1 hypervisor
D) Container engine
Correct ANS:
C) Type 1 hypervisor
Rationale:

,Type 1 hypervisors (bare-metal hypervisors) operate directly on
the hardware, offering better performance and security for server
virtualization. They do not require a host operating system, unlike
Type 2 hypervisors.

Question 2 (Fill in the Blank)
Question:
The process of abstracting physical resources into multiple
isolated virtual machines is known as ________ .
Correct ANS:
virtualization
Rationale:
Virtualization is the fundamental technology that abstracts
physical hardware (CPU, memory, storage, network) to create
multiple isolated environments—or virtual machines—that can
run concurrently on the same host.

, Question 3 (True/False)
Question:
True/False: Paravirtualization requires modifications to the guest
operating system to optimize communication with the hypervisor.
Correct ANS:
True
Rationale:
Paravirtualization involves altering the guest OS to interact more
efficiently with the hypervisor. This approach reduces overhead
by enabling the guest to make hypercalls, but it requires an OS
that is aware of the virtualization layer.

Question 4 (Multiple Response)
Question:
Select all virtualization techniques that are commonly employed
in modern environments:
A) Full virtualization
B) Paravirtualization
©2025
, C) Hardware-assisted virtualization
D) Process-level virtualization
E) Link-layer virtualization
Correct ANS:
A, B, C, D
Rationale:
Modern virtualization encompasses full virtualization (complete
abstraction), paravirtualization (modified guest OS), hardware-
assisted virtualization (using technologies like Intel VT-x or
AMD-V), and process-level virtualization (containers). Link-layer
virtualization is typically not considered a primary virtualization
category.

Question 5 (Multiple Choice)
Question:
What is the primary benefit of using hardware-assisted
virtualization (e.g., Intel VT-x, AMD-V) in a virtualized
environment?
A) It eliminates the need for a hypervisor.
