Answer
- A Step 2: canary testing
- B Step 1: shadow testing
Explanation
In shadow testing the new model runs in parallel with the production model with the same requests, without affecting live responses. In canary testing, it is then released to a small subset of production traffic, for example 5% of users, and monitored before being fully rolled out. Rollback testing belongs before deployment.
