Exam AWS Certified AI Practitioner AIF-C01 topic 1 question 78 discussion

A: Delete the custom model. Remove the confidential data from the training dataset. Retrain the custom model. Explanation: If the training dataset contains confidential data, the model may inadvertently learn and generate responses based on that data. The only way to ensure that the model does not generate responses based on the confidential data is to: Remove the confidential data from the training dataset. Retrain the custom model using the updated dataset. This process ensures that the model is not influenced by the sensitive information.

Explanation: Once a model is trained, the data used for training is embedded in its parameters. If confidential data is included in the training dataset, it can influence the responses the model generates. Simply masking or encrypting inference responses will not ensure the model doesn’t generate responses derived from the confidential data; the issue originates in the training process itself.

The correct answer is A. Once a model is trained on confidential data, it must be retrained without it.

Delete the custom model, remove the confidential data, and retrain the model is the best approach because it ensures that the model will not retain or generate responses based on any confidential information

Once a model is trained on data, its outputs may inherently reflect patterns or details derived from the training dataset, including confidential data. To ensure the custom model does not generate inference responses based on confidential data, the only reliable solution is to: - Remove the confidential data from the training dataset. - Retrain the model with the updated dataset. This approach ensures the model is not influenced by sensitive information during inference. Option B is incorrect. Dynamic data masking hides sensitive information in database query results or outputs but does not prevent the model from generating responses influenced by the confidential data. The model would still "know" the sensitive patterns.

The company should mask the confidential information

This is the most efficient method, effectively maintaining data privacy and security.
