AIF-C01 Practice Test

A company has built an image classification model to predict plant diseases from photos of plant leaves. The company wants to evaluate how many images the model classified correctly.

Which evaluation metric should the company use to measure the model's performance?

A. R-squared score

B. Accuracy

C. Root mean squared error (RMSE)

D. Learning rate

An AI practitioner trained a custom model on Amazon Bedrock by using a training dataset that contains confidential data. The AI practitioner wants to ensure that the custom model does not generate inference responses based on confidential data.

How should the AI practitioner prevent responses based on confidential data?

A. Delete the custom model. Remove the confidential data from the training dataset. Retrain the custom model.

B. Mask the confidential data in the inference responses by using dynamic data masking.

C. Encrypt the confidential data in the inference responses by using Amazon SageMaker.

D. Encrypt the confidential data in the custom model by using AWS Key Management Service (AWS KMS).

A company needs to build its own large language model (LLM) based on only the company's private data. The company is concerned about the environmental effect of the training process.

Which Amazon EC2 instance type has the LEAST environmental effect when training LLMs?

A. Amazon EC2 C series

B. Amazon EC2 G series

C. Amazon EC2 P series

D. Amazon EC2 Trn series

A company wants to use a large language model (LLM) to develop a conversational agent. The company needs to prevent the LLM from being manipulated with common prompt engineering techniques to perform undesirable actions or expose sensitive information.

Which action will reduce these risks?

A. Create a prompt template that teaches the LLM to detect attack patterns.

B. Increase the temperature parameter on invocation requests to the LLM.

C. Avoid using LLMs that are not listed in Amazon SageMaker.

D. Decrease the number of input tokens on invocations of the LLM.

A company built a deep learning model for object detection and deployed the model to production.
Which AI process occurs when the model analyzes a new image to identify objects?

A. Training

B. Inference

C. Model deployment

D. Bias correction
