AI0-001 AI Implementation and Operations Practice Question
A data scientist is monitoring a deployed image classification model. Which TWO actions are best practices for detecting model drift? (Choose 2.)
⚠ Common exam trap
CompTIA often tests the distinction between detection and remediation actions, so candidates mistakenly choose retraining (Option A) as a detection method when it is actually a corrective action.
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
✓
Use a holdout test set to periodically evaluate model accuracy.
Periodically evaluating the model on a holdout test set that reflects the current production data distribution is a direct method to detect accuracy degradation caused by model drift. This approach measures whether the model's performance on unseen data has declined over time, which is a key indicator of drift.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Schedule automatic weekly retraining of the model.
Why it's wrong here
Retraining is a remediation action, not a monitoring method.
- ✗
Increase the model's complexity to improve generalization.
Why it's wrong here
Increasing complexity is not a monitoring practice and may cause overfitting.
- ✓
Use a holdout test set to periodically evaluate model accuracy.
Why this is correct
Comparing performance on a static test set reveals concept drift.
- ✗
Monitor the average prediction confidence of the model.
Why it's wrong here
Prediction confidence may not indicate drift; it can be high even on drifted data.
- ✓
Track the distribution of input data over time.
Why this is correct
Detects data drift which may cause model performance degradation.
