AI0-001 AI Implementation and Operations Practice Question
A retail company's ML platform team notices that one of their production models has begun returning predictions with a drastically different distribution than during training. The monitoring dashboard shows the input feature distributions have shifted but no code or model artifacts have changed. The team wants to automatically trigger a retraining pipeline when this condition is detected. Which approach should they implement?
⚠ Common exam trap
Many exam-takers confuse data drift with concept drift or model performance degradation, leading to selection of a monitor that does not directly detect input distribution changes.
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
✓
Configure a data drift monitor that computes statistical distance between live inference inputs and the training baseline, and wire its alert to the retraining pipeline trigger.
The scenario describes data drift: input feature distributions have changed while the model and code remain the same. A data drift monitor that compares live inputs to the training baseline is the correct tool to detect this and can be integrated with the retraining pipeline. Other monitoring types either require labels, focus on label relationships, or are overly sensitive.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure a data drift monitor that computes statistical distance between live inference inputs and the training baseline, and wire its alert to the retraining pipeline trigger.
Why this is correct
This is correct because the scenario describes a change in input feature distributions with no change to model code or artifacts, which is data drift. A drift monitor comparing live inputs to the training baseline detects this and can trigger retraining automatically.
- ✗
Enable concept drift detection by comparing the relationship between features and labels over time and trigger retraining when the mapping changes.
Why it's wrong here
Concept drift refers to changes in the relationship between input features and the target variable, not just the input distribution. The scenario states that only the input feature distributions have shifted, so concept drift detection is not the appropriate trigger here.
- ✗
Implement a model versioning system that records the exact training data hash and triggers retraining whenever the hash of the incoming data differs from the stored hash.
Why it's wrong here
A hash comparison detects any change in data, including benign variations, and would cause excessive retraining. It does not measure statistical drift, so it is too sensitive and not a reliable trigger for the described condition.
- ✗
Set up a model performance monitor that tracks prediction accuracy against ground truth labels and triggers retraining when accuracy drops below a threshold.
Why it's wrong here
This fails because accuracy monitoring requires ground truth labels, which may not be available in real time, and the scenario specifically points to input distribution shift rather than degraded accuracy. It would not detect the drift condition described.
