AI0-001 AI Security, Ethics and Governance Practice Question

Which TWO of the following are effective defenses against adversarial examples in AI systems?

⚠ Common exam trap

The AI0-001 exam often tests the misconception that ensemble methods or model simplification inherently improve adversarial robustness, when in fact they do not address the fundamental mechanism of adversarial perturbations and may even weaken defenses.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Train the model with adversarial examples (adversarial training)

Adversarial training (A) is effective because it exposes the model to perturbed inputs during training, forcing it to learn robust decision boundaries that are less sensitive to small, malicious perturbations. Input sanitization and feature squeezing (D) reduce the attack surface by compressing input features (e.g., reducing bit depth or spatial smoothing) to eliminate adversarial noise before inference, making it harder for an attacker to craft a successful perturbation.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Train the model with adversarial examples (adversarial training)

    Why this is correct

    Adversarial training hardens the model against perturbations.

  • Use an ensemble of models and majority voting

    Why it's wrong here

    Ensembles do not inherently protect against adversarial attacks.

  • Increase the model's sensitivity to input changes

    Why it's wrong here

    Higher sensitivity increases vulnerability to perturbations.

  • Implement input sanitization and feature squeezing

    Why this is correct

    Sanitization reduces the space for adversarial perturbations.

  • Reduce model complexity through pruning

    Why it's wrong here

    Pruning may inadvertently remove robustness.
