AI0-001 AI Security, Ethics and Governance Practice Question
Exhibit
Refer to the exhibit. ``` [ERROR] 2025-04-01 15:12:33 - InferenceEngine-7: Input tensor contains NaN values for feature 'age'. Model 'loan_model_v3' returning error code -1. [WARN] 2025-04-01 15:12:34 - SecurityFilter: Input flagged as potentially adversarial (score: 0.89). Action: blocked. [INFO] 2025-04-01 15:12:35 - API Gateway: Request from 192.168.1.10 blocked due to security filter alert. ```
Refer to the exhibit. A system administrator sees these logs from an AI inference pipeline. What is the most likely sequence of events?
⚠ Common exam trap
The AI0-001 exam often tests the distinction between a security filter successfully blocking an attack versus the filter failing or the model producing an error, leading candidates to confuse a blocked adversarial input with a model error or data poisoning.
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
✓
An adversarial input was blocked by the security filter
The logs show the security filter actively blocking an input (e.g., 'Blocked by security filter: input contains adversarial pattern') and then the pipeline continuing normally. This indicates the filter detected and stopped an adversarial input before it reached the model, preventing any error or corruption. The absence of NaN or model errors confirms the filter functioned as designed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Data poisoning corrupted the model, causing NaN outputs
Why it's wrong here
The error is at inference, not model corruption.
- ✗
The security filter failed to detect an attack and the model returned an error
Why it's wrong here
The filter detected and blocked the attack.
- ✗
A non-adversarial input caused a NaN error due to missing data
Why it's wrong here
The filter considered it adversarial, overriding the NaN possibility.
- ✓
An adversarial input was blocked by the security filter
Why this is correct
The security filter flagged the input as adversarial and blocked it.
