問題文
Assemble the full loop from detecting degradation to serving an improved model. Which sequence is complete?
選択肢
- Monitoring detects the breach, a person retrains by hand, and the deployment is updated in place
- Monitoring detects the breach and the endpoint automatically falls back to the previous model version, after which the team investigates at its own pace and submits a retraining pipeline once the cause of the degradation is understood
- Monitoring detects the breach and retrains and redeploys the model automatically
- Monitoring detects the threshold breach and raises an event, an event handler submits the retraining pipeline, the pipeline's evaluation gate decides whether to register, and a staged rollout moves traffic to the new deployment
