1. A systems administrator is tasked with selecting an operating system for a network of
corporate servers that require high stability, modularity, and open-source customization
without licensing fees. Which operating system best meets these organizational
requirements?
A. Windows Server
B. macOS
C. Linux
D. Unix
Answer: C
Rationale: Linux is an open-source, highly stable, and modular operating system available
without licensing fees, making it ideal for corporate server infrastructure requiring custom
deployment.
2. An employee needs a hardware component that temporarily stores data and instructions
currently in use by the central processing unit (CPU) to ensure rapid access during tasks.
Which component fulfills this function?
A. Hard Disk Drive (HDD)
B. Read-Only Memory (ROM)
C. Random Access Memory (RAM)
D. Solid State Drive (SSD)
Answer: C
Rationale: Random Access Memory (RAM) serves as the primary volatile memory of a
computer, holding execution data temporarily for fast CPU retrieval during processing
operations.
3. An IT specialist is setting up a local network for a small business. Which network device
primarily forwards data packets between different computer networks using IP addresses?
A. Switch
,B. Router
C. Hub
D. Repeater
Answer: B
Rationale: A router inspects destination IP addresses within packet headers to direct data
traffic efficiently between separate subnets and distinct networks.
4. A software developer is designing an application that requires raw data to be
transformed into meaningful information for end-users. What represents the primary
distinction between data and information?
A. Data is processed, while information consists of raw, unorganized facts.
B. Information is raw data that has been structured, processed, and given context.
C. Data requires human interpretation, whereas information is strictly machine-generated.
D. Information and data are synonymous terms in computer science.
Answer: B
Rationale: Data comprises unorganized, raw facts, while information is the resulting output
after data is processed, structured, and presented within a meaningful context.
5. A database administrator needs to create a structured repository that stores data in
related tables consisting of rows and columns. Which software model should be
implemented?
A. Relational Database Management System (RDBMS)
B. Flat File Database
C. Hierarchical Database System
D. Network Database Model
Answer: A
Rationale: An RDBMS organizes data into structured two-dimensional tables (relations) of
rows and columns, enforcing data integrity through keys and relationships.
,6. A security consultant recommends enforcing multi-factor authentication (MFA) across a
corporate enterprise. Which combination demonstrates true multi-factor authentication?
A. A password and a PIN
B. A password and a security question answer
C. A smart card and a personal PIN
D. A password and a fingerprint scan
Answer: D
Rationale: True MFA requires two or more distinct authentication factors, such as something
you know (password) and something you are (fingerprint scan).
7. An organization decides to migrate its physical server hardware to a cloud environment
where the vendor supplies virtualized computing resources, storage, and networking, but
the organization manages the operating systems and software applications. Which cloud
service model is being utilized?
A. Software as a Service (SaaS)
B. Infrastructure as a Service (IaaS)
C. Platform as a Service (PaaS)
D. Function as a Service (FaaS)
Answer: B
Rationale: Infrastructure as a Service (IaaS) provides virtualized hardware resources over the
internet, leaving operating system and application management to the client organization.
8. An entry-level technician is troubleshooting a network workstation that cannot connect
to the local network. The network link light on the network interface card (NIC) is off.
What is the most logical initial troubleshooting step?
A. Reinstall the network driver software.
B. Replace the router with a new device.
C. Inspect and verify physical cable connectivity.
D. Reconfigure the local IP address settings.
, Answer: C
Rationale: Methodical troubleshooting dictates starting with the physical layer (Layer 1) to
verify cables and hardware links before attempting complex software modifications.
9. A business analyst is documenting the core components of an information system. Which
set correctly identifies the five standard components of an information system?
A. Hardware, Software, Data, People, and Procedures
B. Processing, Input, Output, Storage, and Bandwidth
C. Routers, Switches, Servers, Workstations, and Cables
D. Input, Output, Logic, Storage, and Transmission
Answer: A
Rationale: An information system fundamentally consists of hardware, software, data, people,
and procedures working together to gather, process, store, and distribute information.
10. A computer science student learns that the CPU executes software instructions through
a continuous machine cycle. What are the four basic operations of the CPU machine cycle?
A. Input, Processing, Storage, Output
B. Fetch, Decode, Execute, Store
C. Read, Write, Compile, Run
D. Load, Translate, Compute, Save
Answer: B
Rationale: The CPU machine cycle follows four primary steps sequentially: Fetching the
instruction from memory, Decoding it into machine commands, Executing the action, and
Storing the result.
11. An enterprise network administrator wants to dynamically assign IP addresses, subnet
masks, and default gateways to client computers on the network automatically. Which
network protocol should be configured?
A. Domain Name System (DNS)
B. Dynamic Host Configuration Protocol (DHCP)
