,SECTION ONE: QUESTIONS 1–100
1. A user reports that their computer is running slowly and displaying unexpected pop-up advertisements.
What is the most likely cause of this issue?
A. Insufficient RAM
B. A malware infection
C. A failing power supply
D. An outdated web browser
🟢 B. A malware infection
🔴 RATIONALE: The symptoms described—slow performance and unexpected pop-ups—are classic indicators
of adware or other malware infections. Malware consumes system resources and disrupts normal operations.
While insufficient RAM (A) and outdated browsers (D) can cause slowness, they do not typically generate pop-
up ads. A failing power supply (C) would usually cause random shutdowns or instability, not pop-ups.
2. Which of the following protocols is used to securely transfer files over a network?
A. HTTP
B. FTP
C. SFTP
D. SNMP
🟢 C. SFTP
🔴 RATIONALE: SFTP (Secure File Transfer Protocol) provides secure file transfer by encrypting both commands
and data, making it the preferred choice over standard FTP (B) for sensitive information. HTTP (A) is for web
,traffic, and SNMP (D) is for network management.
3. What does the term "phishing" refer to in the context of cybersecurity?
A. A type of network scanning tool
B. A fraudulent attempt to obtain sensitive information
C. A hardware failure in network equipment
D. A method of encrypting files for backup
🟢 B. A fraudulent attempt to obtain sensitive information
🔴 RATIONALE: Phishing is a social engineering attack where an attacker masquerades as a trustworthy entity
to trick victims into revealing sensitive data like passwords or credit card numbers. It is not a tool (A), a
hardware failure (C), nor a backup encryption method (D) .
4. Which device is primarily used to connect multiple devices within a single local area network (LAN) and
directs data based on MAC addresses?
A. Router
B. Modem
C. Switch
D. Firewall
🟢 C. Switch
🔴 RATIONALE: A switch operates at the Data Link layer of the OSI model and uses MAC addresses to forward
data frames between devices on the same LAN. A router (A) connects different networks, a modem (B)
modulates/demodulates signals, and a firewall (D) filters traffic based on security rules .
, 5. In a Windows environment, what is the primary purpose of User Account Control (UAC)?
A. To manage user passwords
B. To prevent unauthorized changes to the operating system
C. To encrypt user data on the hard drive
D. To monitor user application usage
🟢 B. To prevent unauthorized changes to the operating system
🔴 RATIONALE: UAC is a security component that prompts for permission or administrator credentials before
allowing actions that could affect system settings or security. It helps prevent malware from making
unauthorized system changes, not for password management (A), data encryption (C), or monitoring usage (D) .
6. Which of the following is an example of open-source software?
A. Microsoft Windows 11
B. Adobe Photoshop
C. Linux
D. macOS
🟢 C. Linux
🔴 RATIONALE: Linux is a prominent open-source operating system whose source code is freely available for
modification and distribution. Windows (A), Adobe Photoshop (B), and macOS (D) are proprietary software
products .
7. The Sarbanes-Oxley Act (SOX) primarily addresses which of the following?
