DDisabling all health checks during deploys
Answer & Solution
Correct answer: B. Routing a small share of traffic to a new version
Canary deployment routes a small percentage (1-5%) of real traffic to the new version, monitors metrics and errors, then progressively shifts more traffic if healthy. Limits blast radius of bad releases.
