Q132
What happens when you upgrade your Azure MLS model without retraining it?
AModel accuracy improves
BModel may become less effective
CModel continues as before
DModel accuracy decreases significantly
Explanation
Without retraining, the model may not benefit from improvements in the service and could lose predictive power. Options A and D are overly positive or negative, while C implies stasis which isn't guaranteed.
