Question 22
Application DeliveryCanary deployment does what?
Correct answer: A
Explanation
A canary deployment releases a new version to a small subset of users first, then expands exposure if it behaves as expected. This "gradually shifts traffic to new version" approach limits risk by allowing monitoring and rollback before full rollout.
Why each option is right or wrong
A. Gradually shifts traffic to new version
A canary deployment introduces the new release to only a small fraction of live traffic first, then increases that share in stages if metrics remain acceptable. In practice, this lets operators monitor error rates, latency, and user impact before routing the remaining traffic, so the deployment is not all-at-once but progressively expanded.
B. Instantly replaces old version
C. Creates new namespace
D. Deletes old version immediately
