問題文
A new classification model version is ready to replace the current one in a production pipeline that handles 50,000 documents a day. Which two elements must the rollout plan include? (Select two.)
選択肢
- Running both versions on all traffic permanently and using the old version's output.
- Switching all traffic at once once the evaluation set passes, since the evaluation already demonstrated the new version is better.
- Announcing the change to downstream consumers so they can adjust their own parsing.
- A way to return all traffic to the previous version immediately, without waiting for a code release.
- Routing a small fraction of traffic to the new version first and comparing its measured results against the current one on the same inputs.
