Which deployment pattern runs the new model alongside the old model and gradually shifts traffic to the new one?
Answer: Canary / gradual rollout
Canary deployment incrementally shifts a small percentage of traffic to the new model, limiting risk before full cutover.
Model monitoring in production should track which of the following to detect data drift?
Answer: Distribution of input features over time
Monitoring the statistical distribution of input features reveals data drift, which can degrade model performance over time.
What does 'model staleness' mean in the CAP lifecycle management context?
Answer: Model performance has degraded because the real-world environment has changed
Model staleness occurs when concept drift causes a previously accurate model to become less effective as the underlying patterns change.
Which artifact MUST be version-controlled alongside model code to ensure reproducibility?
Answer: Training data schema and model hyperparameters
Reproducibility requires version-controlling the training data schema, hyperparameters, and code so the exact model state can be recreated.
A/B testing in model deployment is used to:
Answer: Compare two model versions using live traffic and business metrics
A/B testing exposes different user groups to each model version and measures real business outcomes to determine the superior model.
Which document formally describes a model's intended use, limitations, and performance across subgroups?
Answer: Model card
A model card is a standardized documentation artifact that captures intended use cases, performance benchmarks, and fairness considerations.
