,Question 1
Which of the following best describes the primary purpose of a security governance program?
A) To ensure all security tools are properly configured
B) To align security strategy with business objectives and manage risk within the organization's
risk appetite
C) To monitor network traffic for intrusions
D) To manage user access to systems
Correct Answer: B
Security governance is the framework of policies, processes, and controls that directs and
manages the organization's security program. Its primary purpose is to align security with
business strategy and ensure risk is managed according to the organization's defined risk
appetite. Tool configuration (A), network monitoring (C), and access management (D) are
operational activities that support governance but are not the primary purpose of the
governance program itself. This aligns with Domain 1 of the CISSP CBK.
Question 2
When conducting a quantitative risk analysis, the Annualized Loss Expectancy is calculated by
which formula?
A) ALE = Asset Value × Exposure Factor
B) ALE = Single Loss Expectancy × Annualized Rate of Occurrence
C) ALE = Annualized Rate of Occurrence × Asset Value
D) ALE = Exposure Factor × Annualized Rate of Occurrence
Correct Answer: B
The correct formula for Annualized Loss Expectancy is ALE = SLE × ARO. The Single Loss
,Expectancy represents the cost of a single loss event, and the Annualized Rate of Occurrence
represents how many times that loss is expected to occur annually. Multiplying them provides the
annual expected loss. SLE itself is calculated as Asset Value × Exposure Factor (A), which is a
component of the formula but not the complete ALE calculation.
Question 3
Under the GDPR, what is the maximum timeframe for notifying the supervisory authority of a
personal data breach after becoming aware of it?
A) 24 hours
B) 72 hours
C) 7 calendar days
D) 30 calendar days
Correct Answer: B
Article 33 of the GDPR requires that data controllers notify the supervisory authority of a
personal data breach without undue delay and, where feasible, not later than 72 hours after
becoming aware of it. If notification is not made within 72 hours, the controller must provide
reasons for the delay. The 72-hour requirement is a defining feature of GDPR breach
notification and a key testable concept in Domain 1.
Question 4
What is the primary purpose of data classification within an organization?
A) To reduce storage costs by deleting unnecessary data
B) To identify the value and sensitivity of data and apply appropriate security controls based on
classification level
, C) To comply with software licensing requirements
D) To organize data alphabetically for easier retrieval
Correct Answer: B
Data classification is the process of categorizing data based on its value, sensitivity, and
criticality to the organization. The purpose is to apply appropriate security controls proportional
to the data's importance. While classification may inform retention decisions (A), its primary
purpose is security control alignment. Compliance and organization are secondary benefits. This
is a core concept in Domain 2: Asset Security.
Question 5
Which security model is specifically designed to address data integrity through well-formed
transactions and separation of duties?
A) Bell-LaPadula model
B) Biba model
C) Clark-Wilson model
D) Brewer-Nash model
Correct Answer: C
The Clark-Wilson model is specifically designed for commercial environments where data
integrity is paramount. It uses two key concepts: well-formed transactions (Transformation
Procedures) that ensure data is modified only in authorized ways, and separation of duties to
prevent fraud. Bell-LaPadula (A) addresses confidentiality. Biba (B) addresses integrity but
through a lattice model. Brewer-Nash (D) addresses conflicts of interest.
