A county GIS rollout introduced bad tiles after an image change. Ops need to restore the previous ReplicaSet revision quickly. Which action matches that goal?
Select an answer to reveal the explanation.
Short Explanation
When a release goes sideways, you want the last known-good build back on the road—not a permanent shutdown. kubectl rollout undo is the Deployment's rewind button: it brings back the previous ReplicaSet revision.
Full Explanation
kubectl rollout undo Deployment restores the previous Pod template revision recorded in the Deployment's rollout history, recreating the prior ReplicaSet. Deleting the Service or changing only selectors does not undo the bad image. Scaling to zero removes capacity rather than restoring the last good revision.
