AI0-001 Implementing AI Solutions Practice Question
In the AI project lifecycle, after a model is trained and evaluated, it is deployed to a production environment. What is the NEXT critical step to ensure the model continues to perform well over time?
⚠ Common exam trap
The trap is jumping to remediation actions (retrain, collect data) instead of the diagnostic step (monitoring); the exam tests whether you understand that you must detect degradation before you can fix it.

Correct answer & explanation
✓
Monitoring the model's performance and data drift
After deployment, the next critical step is monitoring the model's performance and detecting data drift, because production data distributions change over time and model accuracy degrades silently. Monitoring closes the MLOps loop by feeding real-world performance signals back to the team, enabling timely retraining or rollback. Without monitoring, degradation goes unnoticed until business impact occurs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Collect more training data
Why it's wrong here
Collecting more training data addresses model accuracy before deployment, not ongoing production health. Post-deployment, the priority is monitoring for data drift and performance degradation so retraining triggers correctly. More data would be the right choice when evaluation shows the model underfits or lacks representative examples.
- ✗
Archive the model and start a new project
Why it's wrong here
Archiving discards the deployed model's monitoring and feedback loop, so performance decay from data drift goes undetected. Archiving suits retiring a superseded model after a replacement is validated, not sustaining one already serving production traffic.
- ✓
Monitoring the model's performance and data drift
Why this is correct
Monitoring performance and data drift detects degradation once the model is live, satisfying the requirement to sustain accuracy over time. Data drift measures changes in input feature distributions; performance monitoring tracks prediction quality against ground truth. Together they trigger retraining before silent failures erode business outcomes.
- ✗
Re-train the model from scratch
Why it's wrong here
Retraining from scratch discards learned weights and requires labelled data and compute, while drift is addressed by monitoring and periodic refresh. Full retraining fits rebuilding after major architecture or data-schema changes, not routine upkeep of a deployed model.
