INTRODUCTION
This examination assesses foundational and applied knowledge in information security and
cybersecurity operations. It is designed to evaluate a candidate’s ability to identify threats,
apply security controls, interpret risk scenarios, and implement best practices in real-world
,environments. The exam emphasizes scenario-based problem solving, requiring learners to
demonstrate both theoretical understanding and practical decision-making skills. Topics
include network defense, encryption methods, access control mechanisms, compliance
standards, and incident response procedures. Candidates are expected to apply analytical
reasoning to security challenges commonly encountered in organizational IT environments
and cybersecurity frameworks.
SECTION ONE: QUESTIONS 1–50
1. Which principle ensures that data is not altered during transmission?
A. Confidentiality
B. Integrity
C. Availability
D. Authentication
Correct Answer: B. Integrity
Rationale:
Integrity ensures that data remains accurate and unaltered during storage or
transmission.
2. What is the primary purpose of a firewall?
A. Encrypt data
B. Monitor user behavior
C. Block unauthorized network access
, D. Store passwords
Correct Answer: C. Block unauthorized network access
Rationale:
A firewall filters incoming and outgoing traffic to prevent unauthorized access to
networks.
3. Which attack involves overwhelming a system with traffic?
A. Phishing
B. SQL Injection
C. Denial of Service
D. Brute Force
Correct Answer: C. Denial of Service
Rationale:
A DoS attack floods systems with traffic to disrupt normal operations.
4. What is the function of encryption?
A. Detect malware
B. Convert data into unreadable format
C. Increase bandwidth
D. Log user activity
Correct Answer: D. Log user activity
Rationale:
Encryption transforms readable data into coded form to prevent unauthorized access.
, 5. Which authentication method uses biometrics?
A. Password
B. PIN
C. Fingerprint scan
D. Security token
Correct Answer: A. Password
Rationale:
Biometric authentication uses physical traits such as fingerprints for identity verification.
