Section 1: IT Fundamentals and Infrastructure
Q1: Which of the following is a characteristic of cloud computing?
A. On-demand self-service [CORRECT]
B. Limited scalability
C. Fixed infrastructure costs
D. Local data storage only
Correct Answer: A
Rationale: Cloud computing features on-demand self-service, broad network access, resource
pooling, rapid elasticity, and measured service. Options B, C, and D are not characteristics of
cloud computing.
Q2: A company wants to rent virtualized servers to run their operating systems and applications
without managing the underlying hardware. Which cloud service model are they using?
A. Infrastructure as a Service (IaaS) [CORRECT]
B. Platform as a Service (PaaS)
C. Software as a Service (SaaS)
D. Desktop as a Service (DaaS)

Q3: Which of the following best describes the primary benefit of virtualization?
A. It eliminates the need for operating systems.
B. It allows multiple operating systems to run on a single physical machine. [CORRECT]
C. It increases the speed of the internet connection.
D. It automatically repairs hardware failures.
Correct Answer: B
Rationale: Virtualization allows a single physical machine (host) to run multiple virtual machines
(guests), each with its own OS, improving hardware utilization and flexibility.
Q4: An IT manager is deciding between a peer-to-peer network and a client-server network for a
small office with 5 employees. Which factor makes a peer-to-peer network appropriate in this
scenario?
A. Centralized data security is required.
B. Dedicated network administrators are available.
C. Low cost and simplicity for a very small number of users. [CORRECT]
D. High volume of database transactions is expected.
Correct Answer: C

processing inside the computer?
A. RAM (Random Access Memory)
B. Hard Drive
C. CPU (Central Processing Unit) [CORRECT]

A. To browse the internet
B. To manage hardware and software resources and provide a user interface. [CORRECT]
C. To create spreadsheets
D. To protect against viruses exclusively
Correct Answer: B
