CAE Risk Management & Mitigation 2 ā Questions and Answers
Question 1: Which risk analysis technique assigns numerical probabilities to events in a branching logic diagram to calculate system failure likelihood?
- Failure Mode and Effects Analysis (FMEA)
- Fault Tree Analysis (FTA) (Correct answer)
- Hazard and Operability Study (HAZOP)
- Bow-Tie Analysis
Correct answer: Fault Tree Analysis (FTA)
Fault Tree Analysis uses Boolean logic and probability values in a top-down tree structure to compute the likelihood of a system-level failure.
Question 2: In automotive supply chain risk management, a 'sole-source' supplier arrangement primarily introduces which type of risk?
- Currency fluctuation risk
- Supply disruption concentration risk (Correct answer)
- Intellectual property risk
- Regulatory compliance risk
Correct answer: Supply disruption concentration risk
A sole-source supplier creates concentration risk because any disruptionānatural disaster, insolvency, or quality failureāhas no alternative supply path to mitigate it.
Question 3: The 'risk appetite' of an organization in automotive engineering is best defined as:
- The maximum financial loss the company can absorb
- The level of risk the organization is willing to accept in pursuit of its objectives (Correct answer)
- The residual risk remaining after all controls are applied
- The probability threshold above which risks must be escalated
Correct answer: The level of risk the organization is willing to accept in pursuit of its objectives
Risk appetite defines the amount and type of risk an organization is prepared to accept while pursuing strategic goals, guiding decision-making across engineering programs.
Question 4: During a vehicle program, a Corrective Action Board (CAB) is typically convened in response to:
- Routine design reviews at program milestones
- Emerging or confirmed field quality issues requiring structured resolution (Correct answer)
- Annual supplier performance evaluations
- Regulatory homologation submissions
Correct answer: Emerging or confirmed field quality issues requiring structured resolution
A CAB is triggered when field data or test results reveal a significant quality or safety problem, bringing cross-functional teams together to define root cause and corrective actions.
Question 5: Which ISO standard specifically addresses automotive functional safety and requires risk assessment via Automotive Safety Integrity Levels (ASILs)?
- ISO 9001
- ISO 26262 (Correct answer)
- ISO 14001
- IATF 16949
Correct answer: ISO 26262
ISO 26262 is the international standard for functional safety of electrical and electronic systems in road vehicles, using ASIL A through D to classify hazard severity.
Question 6: A risk heat map plots risk items on axes of probability and impact primarily to:
- Calculate exact monetary expected loss for each risk
- Visually prioritize risks so resources focus on high-likelihood, high-impact items (Correct answer)
- Replace quantitative risk analysis entirely
- Document risk ownership assignments
Correct answer: Visually prioritize risks so resources focus on high-likelihood, high-impact items
The heat map is a qualitative visualization tool that enables rapid prioritization and communication by showing which risks occupy the critical high-probability, high-impact quadrant.
Question 7: In the context of automotive cybersecurity risk management, the standard that provides a framework for identifying and mitigating cyber threats to vehicle systems is:
- AUTOSAR Classic
- ISO/SAE 21434 (Correct answer)
- IEC 61508
- SAE J3016
Correct answer: ISO/SAE 21434
ISO/SAE 21434 defines cybersecurity engineering requirements for road vehicles, including threat analysis, risk assessment (TARA), and cybersecurity lifecycle management.
