, C182 — INTRODUCTION TO IT: COMPREHENSIVE
Questions 1 – 130
OBJECTIVE ASSESSMENT REVIEW
1. The Evolution of Users describes how:
A. Only engineers can use computers today
B. First users were engineers who built and programmed computers, then specialized
employees, and now anyone can be a user
C. Computers have always been accessible to everyone
D. Only government agencies use computers
CORRECT ANSWER B — First users were engineers who built and programmed computers, then
specialized employees, and now anyone can be a user
RATIONALE User evolution: engineers → trained employees → universal access. Early
computers required specialized knowledge. Today, intuitive interfaces make
computing accessible to everyone regardless of technical background.
2. A File Server:
A. Only stores email messages
B. Sends files over the network at the request of clients; responds over LAN within one
location/site; supports both application software and data files
C. Converts domain names to IP addresses
D. Manages print jobs only
CORRECT ANSWER B — Sends files over the network at the request of clients; responds over
LAN within one location/site; supports both application software and data
files
RATIONALE File servers provide centralized file storage and sharing on a local network. They
enable multiple users to access shared files and applications.
,3. A Domain Name Server (DNS):
A. Stores files for network clients
B. Turns a user-friendly domain name like Google.com into an IP address that computers use
to identify each other on the network
C. Manages email communication
D. Provides firewall protection
CORRECT ANSWER B — Turns a user-friendly domain name like Google.com into an IP address
that computers use to identify each other on the network
RATIONALE DNS = internet phonebook. Humans use domain names; computers use IP
addresses. DNS translates between them.
4. Public Key Encryption uses:
A. The same key for encryption and decryption
B. Two keys — a public and private key — for performing encryption and decryption
C. No encryption keys at all
D. Only a single shared password
CORRECT ANSWER B — Two keys — a public and private key — for performing encryption and
decryption
RATIONALE Asymmetric encryption: public key encrypts, private key decrypts. Option A =
symmetric encryption.
, 5. Authentication involves:
A. Only installing antivirus software
B. Proving you are who you say you are — can be done by what you know and what you have
C. Encrypting all network traffic
D. Backing up data regularly
CORRECT ANSWER B — Proving you are who you say you are — can be done by what you know
and what you have
RATIONALE Authentication factors: something you know (password), something you have
(token), something you are (biometrics).
6. The Presentation Tier in multi-tier development:
A. Stores and retrieves data from databases
B. Is where the user interface for the system is developed; shields the user from underlying
logic and data structures
C. Processes business rules and calculations
D. Manages network connections
CORRECT ANSWER B — Is where the user interface for the system is developed; shields the user
from underlying logic and data structures
RATIONALE Presentation Tier = front-end UI layer. It handles display and user input without
containing business logic.
7. System Deployment steps include:
A. Only coding and testing
B. System Conversion, Final Documentation, and End User Training
C. Only hardware installation
D. Marketing and sales
CORRECT ANSWER B — System Conversion, Final Documentation, and End User Training
RATIONALE Deployment = putting the system into production. Conversion, documentation,
and training are essential.
