D. AWS Lambda
Which of the following Amazon AI services can be used to analyze text and detect the sentiment expressed in it?
A. Amazon Polly
B. Amazon Lex
C. Amazon Comprehend
D. Amazon Rekognition
In the context of machine learning, what is overfitting?
A. A model performs well on training data but poorly on unseen data.
B. A model performs equally well on both training and testing data.
C. A model underperforms on both training and testing data.
D. A model performs poorly on training data but well on unseen data.
A company is building a large language model (LLM) question answering chatbot. The
company wants to decrease the number of actions call center employees need to take to
respond to customer questions.
Which business objective should the company use to evaluate the effect of the LLM
chatbot?
A. Website engagement rate
B. Average call duration
C. Corporate social responsibility
D. Regulatory compliance
A company has developed an ML model for image classification. The company wants to
deploy the model to production so that a web application can use the model.
The company needs to implement a solution to host the model and serve predictions
without managing any of the underlying infrastructure.
Which solution will meet these requirements?
A. Use Amazon SageMaker Serverless Inference to deploy the model.
B. Use Amazon CloudFront to deploy the model.
C. Use Amazon API Gateway to host the model and serve predictions.
D. Use AWS Batch to host the model and serve predictions.
Explanation:
Amazon SageMaker Serverless Inference is the correct solution for deploying an ML model
to production in a way that allows a web application to use the model without the need to
manage the underlying infrastructure.
Amazon SageMaker Serverless Inference provides a fully managed environment
for deploying machine learning models. It automatically provisions, scales, and
manages the infrastructure required to host the model, removing the need for the
company to manage servers or other underlying infrastructure.
Why Option A is Correct:
Why Other Options are Incorrect:
Thus, A is the correct answer, as it aligns with the requirement of deploying an ML model
without managing any underlying infrastructure.
A company wants to display the total sales for its top-selling products across various retail
locations in the past 12 months.
Which AWS solution should the company use to automate the generation of graphs?
A. Amazon Q in Amazon EC2
B. Amazon Q Developer
C. Amazon Q in Amazon QuickSight
D. Amazon Q in AWS Chatbot
A company has documents that are missing some words because of a database error. The
company wants to build an ML model that can suggest potential words to fill in the missing
text.
Which type of model meets this requirement?
A. Topic modeling
B. Clustering models
C. Prescriptive ML models
D. BERT-based models
Explanation: BERT-based models (Bidirectional Encoder Representations from Transformers) are suitable for tasks that involve understanding the context of words in a sentence and suggesting missing words. These models use bidirectional training, which considers the context from both directions (left and right of the missing word) to predict the appropriate word to fill in the gaps.
A company uses a foundation model (FM) from Amazon Bedrock for an AI search tool. The
company wants to fine-tune the model to be more accurate by using the company's data.
Which strategy will successfully fine-tune the model?
A. Provide labeled data with the prompt field and the completion field.
B. Prepare the training dataset by creating a .txt file that contains multiple lines in .csv format.
C. Purchase Provisioned Throughput for Amazon Bedrock.
D. Train the model on journals and textbooks.
A company wants to make a chatbot to help customers. The chatbot will help solve
technical problems without human intervention. The company chose a foundation model
(FM) for the chatbot. The chatbot needs to produce responses that adhere to company
tone.
Which solution meets these requirements?
A. Set a low limit on the number of tokens the FM can produce.
B. Use batch inferencing to process detailed responses.
C. Experiment and refine the prompt until the FM produces the desired responses.
D. Define a higher number for the temperature parameter.
Explanation: Experimenting and refining the prompt is the best approach to ensure that the chatbot using a foundation model (FM) produces responses that adhere to the company's tone.
