1. What is the main purpose of network segmentation in cybersecurity?
A. To monitor internet traffic
B. To divide a network into smaller, more secure sections
C. To encrypt network traffic
D. To prevent all unauthorized users from accessing the network
Answer: b) To divide a network into smaller, more secure sections
Rationale: Network segmentation limits the scope of security breaches by dividing a network
into smaller, isolated segments.
2. What does the "CIA" triad stand for in cybersecurity?
A. Control, Integrity, Access
B. Confidentiality, Integrity, Availability
C. Computer, Internet, Authentication
D. Centralized, Integrated, Automated
Answer: b) Confidentiality, Integrity, Availability
Rationale: The CIA triad represents the core principles of cybersecurity: ensuring that data
remains confidential, accurate, and available to authorized users.
3. What is the role of a security operations center (SOC) in cybersecurity?
,A. To design and develop encryption algorithms
B. To monitor and respond to security incidents
C. To manage backup systems
D. To train employees on security best practices
Answer: b) To monitor and respond to security incidents
Rationale: A SOC is a centralized unit that monitors security systems, analyzes threats, and
responds to security incidents in real-time.
4. What does the term "phishing" refer to in cybersecurity?
A. An attack that exploits software vulnerabilities
B. An attempt to trick individuals into revealing sensitive information
C. An attack that steals credit card information from websites
D. A method to disrupt network services
Answer: b) An attempt to trick individuals into revealing sensitive information
Rationale: Phishing typically involves sending fraudulent emails or messages that appear to
come from legitimate sources to steal sensitive information.
5. What does "data breach" mean?
A. Encrypting sensitive data to protect it from unauthorized access
B. The unauthorized access or acquisition of sensitive data
C. Preventing unauthorized access to a network
, D. Creating backup copies of sensitive data
Answer: b) The unauthorized access or acquisition of sensitive data
