Question 1: In a safety-critical aerospace system, what is the impact of "Undefined Behavior" in C/C++ code, and how do you prevent it in your software development?

Which action should you take?

Choose only one option

Undefined behavior only affects software, not hardware systems

Undefined behavior is only a concern in high-level languages, not in C/C++

Undefined behavior can lead to unpredictable results and system failures, and it is prevented by adhering to coding standards and rigorous testing

Undefined behavior is ignored if the system is adequately tested

Question 2: Why are interrupts a key feature in embedded aerospace systems?

Which action should you take?

Choose only one option

They increase system latency

They reduce memory footprint

They simplify system architecture

They allow asynchronous event handling

Question 3: How does "Navier-Stokes Equations" relate to simulation software for aerospace applications, and what challenges do you face in applying them to real-world aerodynamic models?

Which action should you take?

Choose only one option

Navier-Stokes equations are irrelevant in aerospace applications, where simpler models are used

Navier-Stokes equations are only used in academic research, not in actual simulation software

Navier-Stokes equations describe fluid flow, which is critical for simulating aerodynamics, but solving them numerically requires high computational power and careful boundary conditions

Navier-Stokes equations only apply to space applications, not atmospheric ones

Question 4: What is the key advantage of using template programming in C++ for aerospace software development?

Which action should you take?

Choose only one option

To ensure compliance with strict coding standards for aerospace software

To reduce execution time for complex mathematical models

To optimize the memory allocation and minimize the system footprint

To enable the development of generic, reusable components that can work with different data types

Question 5: What is the primary challenge when using the Standard Library's containers (like std::vector) in aerospace software?

Which action should you take?

Choose only one option

Optimizing the container for real-time system use

Ensuring that the container's memory usage is predictable and manageable

Ensuring thread safety when using containers in multi-threaded applications

Reducing the overall size of the container for efficiency

Question 6: What is the most important consideration when implementing fault-tolerant embedded systems for aerospace?

Which action should you take?

Choose only one option

Redundancy

Software portability

Hardware speed

Memory footprint optimization
