Answer: Register the model with the same name as the existing model.
The correct approach is to register the new model with the same name as the existing model. In Azure ML's model registry, when you register a model with the same name as an existing registered model, it automatically creates a new version (incrementing the version number) while preserving all previous versions. This aligns with the community consensus (100% selected B) and official documentation stating that each model registered to the same model name increments the version number. Option A is incorrect because using a different name would create a separate model, not a new version. Option C is wrong as saving to datastore without registration doesn't utilize the versioning capability. Option D is incorrect because deleting the existing model would remove the current version, contradicting the requirement to keep it.

You are retraining an existing model that is already registered in an Azure Machine Learning workspace. You need to register the newly trained model as a new version, ensuring the current version remains in the registry and is not overwritten.
Which action should you take to accomplish this?
A
Register a model with a different name from the existing model and a custom property named version with the value 2.
B
Register the model with the same name as the existing model.
C
Save the new model in the default datastore with the same name as the existing model. Do not register the new model.
D
Delete the existing model and register the new one with the same name.
