1. Which of the following best describes the role of the operating system?
A. It compiles source code into machine language
B. It coordinates hardware resources and provides services to software
C. It determines the maximum storage capacity of the computer
D. It regulates network traffic across routers
Correct Answer: B
Rationale:
• B is correct because the OS manages CPU scheduling, memory allocation, file systems,
and device input/output.
• A describes what a compiler does.
• C is incorrect—hardware determines storage capacity, not the OS.

, • D relates to networking equipment, not an operating system.
2. Which of these is an example of IaaS (Infrastructure as a Service)?
A. Google Docs
B. Amazon EC2 virtual machines
C. GitHub repository hosting
D. Microsoft Excel desktop application
Correct Answer: B
Rationale:
• B is correct because EC2 provides virtualized servers, storage, and networking—classic
IaaS.
• A is SaaS.
• C is also a SaaS offering.
• D is locally installed software, not cloud-based.
3. Which device operates at Layer 2 of the OSI model?
A. Router
B. Switch
C. Hub
D. Firewall
Correct Answer: B
Rationale:
• B is correct: switches use MAC addresses and forward frames at Layer 2 (Data Link).
• A operates at Layer 3.

, • C is a Layer 1 device.
• D may operate at multiple layers, but not primarily Layer 2.
4. What is the main purpose of RAID?
A. To increase processor efficiency
B. To isolate network segments
C. To provide redundancy and/or performance improvements
D. To secure data using encryption
Correct Answer: C
Rationale:
• C is correct: RAID provides redundancy, fault tolerance, and performance benefits.
• A relates to CPU management.
• B describes networking.
• D relates to encryption, not RAID.
5. What is the primary function of DNS?
A. Encrypt network packets
B. Translate URLs into IP addresses
C. Route traffic between networks
D. Provide email filtering
Correct Answer: B
Rationale:
• B is correct: DNS resolves domain names to IP addresses.
• A relates to security.
• C is what routers do.

, • D describes email security systems, not DNS.
6. Which type of memory is volatile?
A. SSD
B. ROM
C. Flash memory
D. RAM
Correct Answer: D
Rationale:
• D is correct: RAM loses data when power is removed.
• A, B, and C are all nonvolatile.
7. A company wants software delivered through the internet without maintaining any
infrastructure. Which cloud model fits?
A. IaaS
B. SaaS
C. PaaS
D. On-premise hosting
Correct Answer: B
Rationale:
• B is correct: SaaS provides ready-to-use applications without infrastructure
management.
• A still requires OS and app management.
• C provides a development platform, not complete apps.
• D is the opposite of cloud hosting.
8. Which backup method only copies files changed since the last full backup?
