   A security team is training a model to detect insider threats. They have a dataset with a very small number of positive examples (insider threats) compared to negative examples (normal behavior). What is the most important consideration when training and evaluating this model?

   • AEnsure the model is trained only on the positive examples to avoid bias
   • BUse a larger test set than training set to improve evaluation
   • CUse appropriate evaluation metrics like precision and recall, not just accuracy, because accuracy can be misleading with imbalanced data
   • DUse accuracy as the primary metric because it is the most widely understood

   What is the purpose of training an AI model?

   • ATo deploy the model to a production environment.
   • BTo adjust the model's parameters so it can accurately map inputs to outputs based on training data.
   • CTo label the training data manually.
   • DTo encrypt the model so it cannot be stolen.
