Q1. A financial services company is building machine learning models on AWS to automate loan approval processes. As an AI Practitioner, you have been tasked to build and maintain data lineage in the context of these machine learning models on…
Answer: D. It ensures data privacy and compliance by tracking the flow and transformation of data
Maintaining data lineage tracks the flow and transformation of data to ensure privacy, security, and regulatory compliance for highly sensitive industries like finance. It does not directly reduce storage costs or optimize machine learning model performance, though it improves auditability.
Q2. A media company is developing a machine learning model to categorize its vast library of content. The data science team is trying to decide between using multi-class or multi-label classification based on the complexity of the content cate…
Answer: D. Multi-class classification assigns each instance to one of several possible classes, while multi-label classification assigns each instance to one or more classes
Multi-class classification restricts each instance to exactly one category, while multi-label classification allows instances to belong to multiple categories simultaneously. Media content often requires multi-label classification because a single video might be categorized as both sports and technology.
Q3. Which AWS service is specifically designed for converting medical speech to text, ensuring compliance with healthcare regulations such as HIPAA?
Answer: B. Amazon Transcribe medical
Amazon Transcribe Medical is specifically trained to understand medical terminologies and clinical conversations, making it ideal for healthcare compliance. Standard Amazon Transcribe handles general speech-to-text tasks but lacks the specialized medical vocabulary required for accurate clinical documentation.
Q4. A company needs a solution that can convert text into human speech so that it can offer audio courses in multiple languages. Which AWS service is the best fit for this use case ?
Answer: A. Amazon Polly
Amazon Polly is a text-to-speech service that uses deep learning to synthesize natural-sounding human speech in multiple languages. Amazon Translate converts text between languages but does not generate audio, while Amazon Lex builds conversational chatbots.
Q5. A research-focused AI company is developing a suite of machine learning models for tasks such as classification and content generation. The data science team needs to choose between discriminative and generative models depending on the spe…
Answer: C. Generative models focus on generating new data from learned patterns, whereas discriminative models classify data by distinguishing between different classes
Generative models learn underlying data distributions to create entirely new content, whereas discriminative models focus on finding decision boundaries to classify existing data. Discriminative models are strictly used for tasks like classification or prediction, not generating new data.
Q6. A traffic monitoring application needs to detect license plate numbers for the vehicles that pass a certain location from 11 PM to 7 AM every day. Which ML-powered AWS service is the right fit for this requirement?
Answer: D. Amazon Rekognition
Amazon Rekognition provides pretrained computer vision APIs to detect objects and text in images or video. Textract is optimized for OCR on structured documents rather than reading text from real-world scenes like license plates.
Q7. A retail company is exploring the use of generative AI to improve its customer experience by personalizing recommendations and automating product descriptions. The company is interested in leveraging pre-built, high-performing Foundation M…
Answer: B. Amazon Bedrock
Amazon Bedrock offers managed access to leading foundation models and supports private customization using your proprietary data. AWS Inferentia is hardware for inference acceleration, whereas Amazon Q applications are purpose-built assistants without fine-tuning capabilities.
Q8. A healthcare company is using machine learning models in Amazon SageMaker to predict patient outcomes based on various health indicators. To comply with regulatory requirements and build trust with medical professionals, the company needs…
Answer: D. Amazon SageMaker Clarify
Amazon SageMaker Clarify provides feature importance graphs to explain how specific inputs influence model predictions during development and inference. Canvas is a no-code tool, JumpStart deploys models, and Ground Truth handles data labeling.
Q9. Match the following AWS services to the respective use cases:
Answer: G. A-2, B-3, C-1
Textract provides OCR for documents, Forecast predicts business metrics, and Kendra delivers ML-powered enterprise search. Matching these core capabilities correctly helps differentiate purpose-built AWS AI services quickly.
Q10. A business needs an automated solution that can extract text from thousands of receipts and invoices generated across all its stores. Which AWS Machine Learning (ML) service can offer the most optimal solution for this use case ?
Answer: C. Amazon Textract
Amazon Textract is optimized to extract printed text, handwriting, and structured data from scanned documents like invoices. Rekognition focuses on identifying sparse text in real-world images rather than processing dense structured forms.
Q11. Which Amazon SageMaker service aggregates and displays data from Amazon SageMaker Model Cards, SageMaker Model Monitor and SageMaker Endpoint services?
Answer: D. Amazon SageMaker Model Dashboard
The SageMaker Model Dashboard provides a centralized view by aggregating metadata, endpoint status, and monitoring alerts. Feature Store manages ML inputs, Data Wrangler prepares data, and JumpStart deploys foundation models.
Q12. A financial services company is developing a machine-learning model to classify loan applications as either "approved" or "denied." To ensure the model performs effectively, the company wants to evaluate how accurately it predicts these ou…
Answer: D. The company should use Accuracy, which measures the proportion of correctly predicted instances (both true positives and true negatives) out of the total number of instances
Accuracy measures the overall proportion of correct binary predictions, fitting the requirement to see correct outcomes. RMSE and R-squared are regression metrics, while F1 Score is typically reserved for evaluating imbalanced datasets.
Q13. A media production company is looking to enhance its creative workflows by using AI to generate high-quality images from text prompts for marketing materials, storyboards, and content development. The company plans to use Amazon Bedrock fo…
Answer: D. Stable Diffusion
Stable Diffusion is the correct choice because it is a foundational image generation model available in Amazon Bedrock that excels at creating photorealistic images from text prompts. Claude, Llama, and Jurassic are large language models built primarily for text generation, reasoning, and summarization tasks.
Q14. A media company is planning to leverage AWS for its AI and machine learning projects, and the development team is evaluating both Amazon Bedrock and Amazon SageMaker JumpStart to accelerate their workflows. The team needs to understand the…
Answer: B. Amazon Bedrock provides foundational models for generative AI applications, whereas Amazon SageMaker JumpStart offers pre-built solutions and one-click deployment for various machine learning models
Amazon Bedrock is a fully managed service that provides access to foundational models from leading AI companies via an API to build generative AI applications. Amazon SageMaker JumpStart provides pre-built solutions and one-click deployment for a broader range of traditional machine learning models.
Q15. An AI-driven healthcare company is focused on reducing its carbon footprint while running machine learning models to analyze large datasets for patient outcomes and research. To achieve this, the company needs to select an Amazon EC2 insta…
