{
"model_registry": [
{
"name": "fraud-detection-v1",
"version": "1",
"stage": "Production",
"artifact_uri": "s3://models/fraud-v1/"
},
{
"name": "fraud-detection-v2",
"version": "2",
"stage": "Staging",
"artifact_uri": "s3://models/fraud-v2/"
},
{
"name": "fraud-detection-v3",
"version": "3",
"stage": "Production",
"artifact_uri": "s3://models/fraud-v3/"
}
]
}
```An ML team uses the model registry above. After deploying version 3 to production, they discover it has a critical bug. What is the fastest way to roll back to a stable version without re-deploying from scratch?
⚠ Common exam trap
CompTIA often tests the misconception that deleting a model version or promoting a staging version is the fastest rollback, when in reality the fastest method is to update the existing deployment's artifact reference to a known stable version.
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
✓
Redeploy version 1 by updating the production deployment to use its artifact
It directly updates the production deployment to reference the artifact of version 1, which is a stable, previously validated version. This avoids the overhead of re-deploying from scratch by simply pointing the existing deployment to a known good artifact in the model registry, leveraging the registry's artifact storage and deployment integration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Promote version 2 from Staging to Production
Why it's wrong here
Version 2 is in Staging and may not be validated for production.
- ✓
Redeploy version 1 by updating the production deployment to use its artifact
Why this is correct
Version 1 is still in Production and can be quickly redeployed.
- ✗
Retrain the model with corrected data
Why it's wrong here
Retraining is time-consuming and not the fastest rollback.
- ✗
Delete version 3 from the registry
Why it's wrong here
Deleting does not change the deployed model.
