Try a sample question
A feature engineering team renames a column from `user_age_raw` to `user_age_years` and normalises it differently. The downstream model passes all unit tests but its precision drops 8 points in production. Which MLOps principle best explains why this happened without any model code changing?
A.The deployment pipeline lacked a canary release gate
B.The CACE principle — changing any input to an ML system can cascade into unexpected behaviour changes
C.The model registry was not updated to reflect the new feature schema
D.Continuous training was disabled, so the model weights were stale
