AI0-001 AI Implementation and Operations Practice Question
A retail bank deploys an AI model that approves or declines small-business loan applications. Regulators require the bank to explain any adverse decision to the applicant in plain language. The model is a gradient-boosted ensemble over dozens of features, and the bank's data scientists cannot easily describe why a specific applicant was declined. Which approach best satisfies the regulatory requirement?
⚠ Common exam trap
The trap here is conflating global model interpretability, which explains average behavior, with local explainability, which is what an individual adverse-action notice actually requires.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply a local explanation technique such as SHAP values to identify the features that most influenced the individual applicant's score and translate them into plain-language reasons.
Regulatory adverse-action requirements demand case-specific reasons for each declined applicant. Local explanation techniques such as SHAP values attribute an individual prediction to its contributing features, which can then be rendered in plain language. Global feature importance, aggregate audit results, and swapping in a simpler model either describe the population rather than the individual or disrupt the production system without addressing the disclosure need.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Apply a local explanation technique such as SHAP values to identify the features that most influenced the individual applicant's score and translate them into plain-language reasons.
Why this is correct
Local explanation methods attribute a specific prediction to its contributing features for that individual case, which is exactly what an adverse-action explanation requires. Translating the top contributing features into plain language gives applicants a faithful, case-specific reason for the decline and provides the audit trail regulators expect from a complex ensemble model.
- ✗
Publish the model's global feature importance rankings alongside each decision notice so applicants see which factors matter most overall.
Why it's wrong here
Global feature importance describes the model's average behavior across the whole population, not the reasons for one applicant's specific decline. Regulators require an explanation of the individual adverse decision, so population-level rankings do not satisfy the requirement and could even mislead an applicant about the factors that drove their particular outcome.
- ✗
Replace the gradient-boosted ensemble with a single decision tree so the decision path itself can be shown to the applicant.
Why it's wrong here
A single decision tree is inherently interpretable, but replacing the production model sacrifices predictive performance and requires full retraining, validation, and re-approval. The requirement is to explain decisions, not to change the model, and a simpler model may still fail to capture the risk patterns the bank relies on, making this an unnecessarily disruptive response.
- ✗
Provide applicants with the model's overall accuracy and fairness audit results to demonstrate that the system is trustworthy.
Why it's wrong here
Aggregate accuracy and fairness audits speak to the system's general reliability, not to why a particular applicant was declined. Adverse-action requirements are about individual, case-specific reasons, so population-level trust metrics do not fulfill the disclosure obligation and leave the declined applicant without the explanation they are entitled to.
