Correct answer & explanation
✓
Implement canary deployments with traffic splitting
Phased rollouts (canary) and gradual traffic shifting allow validation and rollback. Feature flags enable toggling features without redeployment. Automated rollback policies ensure quick recovery. Direct rollout to production is risky. Manual rollback is slow.
