Selected Answer: D

A) Eliminated - creating a new API in API Gateway requires managing two separate APIs, which adds unnecessary complexity. B) Eliminated - This is a direct cutover approach, not a gradual rollout to a limited number of users. If issues arise, all users are impacted, which is not safe or transparent. C) Eliminated - It is not relevant to the question's requirement D) Correct - It allows gradual exposure of the new API version to a subset of users, minimizing risk.

Selected Answer: D

Canary deployments allow you to divert a percentage of your API traffic to a new API version, enabling you to test how the new version will perform under real-world conditions without fully replacing the previous version. This is especially useful for reducing the risk associated with deploying new versions.
