Question 9
UnclassifiedWhich deployment pattern routes a small percentage of production traffic to a new model to validate it before full rollout?
Correct answer: B
Explanation
Canary deployment sends a “small percentage of production traffic” to a new model first, so teams can validate performance and behavior before wider exposure. This staged rollout limits risk and allows monitoring before “full rollout” to all users.
Why each option is right or wrong
A. Big-bang deployment
B. Canary deployment
A canary deployment is the staged release pattern used when a new model is exposed to only a small slice of live traffic first, typically a few percent, so its behavior can be observed under real production conditions before broader exposure. The defining feature is the gradual increase from that initial low-percentage rollout to 100% only after validation, which distinguishes it from an immediate full deployment.
C. Blue-green deployment
D. Cold start
