1. What is the primary objective of cybersecurity within an
organization?
A. To prevent employees from accessing the internet
B. To protect information systems, networks, applications, and data from
unauthorized access, disruption, alteration, or destruction
C. To eliminate every possible vulnerability from an organization
D. To replace physical security controls with digital security controls
Answer: B. To protect information systems, networks, applications,
and data from unauthorized access, disruption, alteration, or
destruction
Rationale: Cybersecurity is a broad discipline focused on protecting
the confidentiality, integrity, and availability of information and
information systems. Although eliminating vulnerabilities is desirable,
achieving zero vulnerabilities is generally unrealistic. Cybersecurity
combines preventive, detective, corrective, administrative, technical,
and physical controls to manage risk and protect organizational assets.
2. An employee receives an email appearing to come from the
organization's IT department. The email asks the employee to click
a link and immediately verify their password because their account
1
,will otherwise be disabled. What type of attack is most likely
occurring?
A. Distributed denial-of-service attack
B. Phishing
C. Port scanning
D. Data fragmentation
Answer: B. Phishing
Rationale: Phishing is a social-engineering technique in which an
attacker uses deceptive communications to trick a victim into revealing
credentials, installing malware, transferring money, or performing
another unauthorized action. Urgency, threats of account suspension,
suspicious links, and requests for credentials are common phishing
indicators.
3. Which security principle is directly violated when an
unauthorized user obtains access to confidential customer records?
A. Availability
B. Confidentiality
C. Integrity
D. Non-repudiation
Answer: B. Confidentiality
Rationale: Confidentiality ensures that information is accessible only
to authorized individuals, systems, or processes. Unauthorized
disclosure or access to customer records represents a confidentiality
failure. Integrity concerns unauthorized modification, while
availability concerns reliable access to information and systems.

,4. A database administrator discovers that several customer records
were changed without authorization. The database remained
accessible throughout the incident. Which component of the CIA
triad was primarily compromised?
A. Confidentiality
B. Integrity
C. Availability
D. Authentication
Answer: B. Integrity
Rationale: Integrity ensures that information remains accurate,
complete, and protected against unauthorized modification or
destruction. Because the records were altered without authorization,
integrity was compromised. The fact that the database remained
available does not eliminate the integrity violation.
5. A company deploys redundant servers so that customers can
continue using an application if one server fails. Which security
objective is this control primarily supporting?
A. Confidentiality
B. Integrity
C. Availability
D. Authentication
Answer: C. Availability
Rationale: Availability means that authorized users can access
systems, applications, and information when required. Redundant
servers reduce the impact of individual hardware failures and improve
service availability. Other availability mechanisms include clustering,
backups, failover systems, load balancing, and disaster recovery
procedures.

, 6. Which statement best describes the principle of least privilege?
A. Users should receive administrator access so they can complete tasks
efficiently
B. Users should receive only the permissions necessary to perform their
authorized responsibilities
C. All employees should have identical permissions
D. Users should have no permissions until an incident occurs
Answer: B. Users should receive only the permissions necessary to
perform their authorized responsibilities
Rationale: Least privilege limits users, applications, and processes to
the minimum permissions required for legitimate activities. This
reduces the potential impact of compromised accounts, insider threats,
malware, and accidental misuse.
7. An organization requires employees to enter a password and then
approve a login notification on a registered mobile device. What
security mechanism is being used?
A. Single-factor authentication
B. Multi-factor authentication
C. Data masking
D. Network segmentation
Answer: B. Multi-factor authentication
Rationale: Multi-factor authentication requires two or more
authentication factors from different categories, such as something
you know, something you have, or something you are. A password
represents something the user knows, while approval through a
registered device represents something the user possesses.
