The correct answer is to apply LIME for local explanations and SHAP for both global and local feature contributions. LIME, or Local Interpretable Model-agnostic Explanations, works by perturbing input data around a single prediction to build a simple, interpretable surrogate model, making it ideal for explaining why a specific loan application was approved or denied. SHAP, or SHapley Additive exPlanations, uses game theory to assign each feature a contribution value, offering a consistent and mathematically grounded view of how features impact predictions both for individual cases and across the entire dataset. On the CompTIA AI+ AI0-001 exam, this question tests your understanding that regulatory review demands per-instance transparency, not just global feature importance—a common trap is choosing feature importance alone, which lacks local granularity. Remember the mnemonic: “LIME lights the local path, SHAP shares the full map.”
AI0-001 AI Implementation and Operations Practice Question
This AI0-001 practice question tests your understanding of ai implementation and operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO techniques are most effective for ensuring model explainability in a production loan approval AI system subject to regulatory review? (Select TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use SHAP values to understand feature contributions
Options C and D are correct. Option C is correct because LIME provides local explanations for individual predictions. Option D is correct because SHAP values quantify feature contributions globally and locally. Option A is wrong because feature importance gives global view but not per-instance. Option B is wrong while decision trees are interpretable, they may not be the deployed model. Option E is wrong because black-box models are inherently uninterpretable without post-hoc methods.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Replace the model with a decision tree for transparency
Why it's wrong here
May not be feasible if deep learning is required.
✓
Use SHAP values to understand feature contributions
Why this is correct
SHAP provides consistent and theoretically grounded explanations.
Related concept
Static NAT maps one inside address to one outside address.
✗
Rely on the model's internal attention weights (if transformer-based)
Why it's wrong here
Attention weights are not always reliable explanations.
✓
Apply LIME to generate local explanations for each prediction
Why this is correct
LIME approximates model behavior locally.
Related concept
Static NAT maps one inside address to one outside address.
✗
Calculate global feature importance using permutation importance
Why it's wrong here
Global importance doesn't explain individual decisions.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related AI0-001 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Use SHAP values to understand feature contributions — Options C and D are correct. Option C is correct because LIME provides local explanations for individual predictions. Option D is correct because SHAP values quantify feature contributions globally and locally. Option A is wrong because feature importance gives global view but not per-instance. Option B is wrong while decision trees are interpretable, they may not be the deployed model. Option E is wrong because black-box models are inherently uninterpretable without post-hoc methods.

Variation 1. A healthcare AI system that diagnoses medical images must provide explanations for its predictions to comply with regulatory requirements. Which technique should the team implement?
medium
A.Reduce the model's accuracy to make it simpler.
B.Only deploy rule-based systems.
✓ C.Apply model interpretability methods such as SHAP or LIME.
D.Use a more complex deep learning model.
Why C: Option C is correct because SHAP (SHapley Additive exPlanations) and LIME (Local Interpretable Model-agnostic Explanations) are established model interpretability techniques that provide per-prediction explanations, which are essential for regulatory compliance in healthcare AI. These methods generate feature attribution scores or local surrogate models to explain why a specific diagnosis was made, meeting transparency requirements without sacrificing model performance.
