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
✓
Blue/green deployment using endpoint updates
SageMaker's blue/green deployment (using endpoint updates with production variants) allows traffic shifting and rollback. A/B testing is for testing variants, not zero-downtime updates by itself. Canary deployment is a type of blue/green but not a separate AWS feature. Multi-model endpoints are for hosting multiple models.
