    A potential source of harm
    60s
  • Q4
    What is the purpose of a Safety Concept in ISO 26262?
    To outline the system's safety goals and mechanisms
    To assess the environmental impact of the vehicle
    To create a marketing plan for the product

    Regression testing
    Safety reviews and audits
    Marketing approval
    Unit testing
    60s
  • Q6
    The ISO 26262 development process is characterized by:
    An agile, iterative approach
    A spiral model
    A V-model with iterative refinement
    A linear, waterfall approach
    60s
  • Q7
    What is the main difference between ASIL B and ASIL D?
    The cost of development
    The complexity of the software involved
    The level of risk associated with the potential harm
    The amount of paperwork required
    60s
  • Q8
    Fault Tree Analysis (FTA) is a technique used in ISO 26262 to:
    Estimate the probability of failure
    Determine the impact of failures on the system

    All of them are correct.

    Identify potential hazards
    60s
  • Q9
    In ISO 26262, "Functional Safety" is defined as:
    The absence of unreasonable risk due to hazards caused by malfunctioning behavior of electrical/electronic systems
    The process of ensuring that a product meets customer requirements
    The degree to which a product is resistant to hacking attempts
    The ability of a system to operate without errors
    60s
  • Q10
    Which of the following is NOT a typical technique for achieving fault tolerance in ISO 26262?
    Diversity
    Redundancy
    Error detection and correction
    Waterfall development model
    60s
  • Q11
    What is the role of a "safety manager" in an ISO 26262 project?
    To ensure that the project adheres to ISO 26262 processes and requirements
    To write software code
    To negotiate contracts with suppliers
    To conduct market research
    60s
  • Q12
    In the context of ISO 26262, "freedom from interference" means:
    Systems should not interfere with the driver's music choices
    Safety features should not be affected by radio frequency interference
    Different parts of a system shouldn't negatively impact each other's safety functions
    Software code should not interfere with hardware operation
    60s
  • Q13
    What are the differences between qualitative and quantitative hazard analysis methods in ISO 26262?
    Qualitative is opinion-based; quantitative uses numerical data
    Qualitative is for hardware; quantitative is for software
    Qualitative uses expert judgment; quantitative calculates probabilities
    There is no difference; they are interchangeable terms
    60s
  • Q14
    Proven in Use (PIU) components in ISO 26262:
    Have a track record of safe operation, offering potential cost savings
    Are always preferred over new components for safety-critical functions
    Never require additional safety analysis or justification
    Are not allowed in ASIL D systems due to their inherent risks
    60s
  • Q15
    Safety validation and confirmation in ISO 26262 involves:
    Marketing the product to potential customers
    Relying solely on simulations, not physical testing
    Only testing the final product, not individual components
    Proving the product works as intended and meets safety requirements
