Answer: D. Amazon SageMaker Role Manager, Amazon SageMaker Model Cards, Amazon SageMaker Model Dashboard
Role Manager controls access, Model Cards document model details for transparency, and Model Dashboard tracks production behavior. Clarify evaluates bias and explainability, while Model Monitor detects drift, so neither fits the strict governance documentation need.
Q4. A legal firm is digitizing a large volume of contracts and other legal documents to streamline document management and analysis. The firm is looking for AWS machine learning services that can automatically detect and extract text from scan…
Answer: B,D. Amazon Textract || Amazon Rekognition
Amazon Textract and Amazon Rekognition both provide optical character recognition capabilities. Textract is optimized for dense documents, while Rekognition handles sparse text within real-world images. Polly, Lex, and Comprehend process or generate text but cannot extract it from images.
Q5. A customer support system frequently encounters database errors that result in incomplete sentences in the logs. The company wants to implement a machine learning model to automatically suggest missing words in these sentences to help reso…
Answer: A. Bidirectional Encoder Representations from Transformers (BERT) based Model
A BERT-based transformer model uses bidirectional context to accurately predict missing words by analyzing surrounding text. Rule-based models lack contextual awareness, while clustering models group data rather than generating text predictions.
Q6. A media company is using Amazon Bedrock to generate content such as headlines, articles, and social media posts. The data science team is particularly interested in understanding how adjusting the Temperature parameter can influence the mo…
Answer: C. Influences the likelihood of the model selecting lower-probability outputs, thereby impacting the creativity of the model's output
The temperature parameter controls the randomness or creativity of a model's responses by influencing the likelihood of selecting lower-probability outputs. For the exam, remember that Top K limits the number of candidates considered, while Top P limits the cumulative percentage of candidates.
Q7. A call center has introduced a chatbot to help employees respond to customer inquiries more efficiently during calls. The goal is to improve overall efficiency and reduce time spent on calls. Which of the following metrics should be monito…
Answer: A. Average Call Duration
Average Call Duration is the correct metric because the stated goal is to improve efficiency and reduce the time agents spend on calls. While First-Call Resolution Rate is an important call center metric, it measures overall customer success rather than the direct time savings targeted by the chatbot.
Q8. A technology company is exploring AWS DeepRacer to introduce its employees to machine learning through an engaging and hands-on platform. The team wants to understand the key features and capabilities of AWS DeepRacer. Which of the followi…
Answer: B. The AWS DeepRacer vehicle is a Wi-Fi enabled, physical vehicle that can drive itself on a physical track
AWS DeepRacer is a physical, Wi-Fi-enabled vehicle that uses reinforcement learning to drive autonomously on physical tracks. It relies on reinforcement learning algorithms, not supervised learning.
Q9. A law firm is handling an increasing volume of legal documents, including contracts, agreements, and case files, and seeks to streamline its document review process by automatically extracting key information such as important clauses, dat…
Answer: A,E,F. Amazon Textract || Amazon Comprehend || Generative AI powered summarization chatbot
Amazon Textract extracts raw text from scanned documents, Amazon Comprehend analyzes that text to find entities, and generative AI summarizes the findings. Watch the wording: a generic chatbot is vague, but combining Textract and Comprehend is the definitive AWS approach for intelligent document processing.
Q10. Which of the following represents the CORRECT statement regarding Amazon SageMaker Model Cards?
Answer: C. Describes how a model should be used in a production environment
Amazon SageMaker Model Cards document essential model details such as intended uses, risk ratings, and evaluation metrics for governance. The wording is slightly ambiguous because option B is technically true, but option C captures the primary purpose of guiding production usage.
Q11. A healthcare analytics company has recently migrated to AWS Cloud and it is preparing to build several Machine Learning (ML) models to predict patient outcomes, optimize treatment plans, and analyze health data trends. The company wants to…
Answer: C. Fix bias by balancing the dataset
Amazon SageMaker Data Wrangler includes built-in transforms to balance datasets, helping address data skew and mitigate potential bias during data preparation. For the exam, remember that Feature Store shares variables and Model Monitor tracks production drift.
Q12. A tech company is building machine learning models using Amazon SageMaker Studio and wants to streamline its development process. The data science team prefers using familiar Integrated Development Environments (IDEs) to write, test, and d…
Answer: A. All
Amazon SageMaker Studio supports multiple integrated development environments, including JupyterLab, Code Editor, and RStudio. Choosing individual options fails because the platform provides this comprehensive suite of tools to accommodate diverse data science workflows.
Q13. A retail company wants to simplify how its employees access and analyze sales data stored in a large database. To achieve this, the company aims to implement a solution that automatically converts plain English text commands, such as "show…
Answer: B. The company should use GPT (Generative Pre-trained Transformer), to interpret natural language inputs and generating coherent outputs, such as SQL queries, by leveraging its understanding of language patterns and structures
Generative Pre-trained Transformers are specifically designed to process natural language and generate human-like text, making them ideal for translating plain English into SQL queries. Amazon Comprehend is built for extracting insights from existing text, not generating new SQL statements.
Q14. A healthcare analytics company is using Amazon SageMaker Automatic Model Tuning (AMT) to optimize its machine learning models for predicting patient outcomes. To ensure the models are performing at their best, the data science team is conf…
Answer: D. None
Amazon SageMaker Automatic Model Tuning can automatically choose hyperparameter ranges, search strategy, and the number of jobs based on your objective metric. For the exam, remember that while you can manually configure these parameters, none are strictly mandatory to initiate tuning.
Q15. A software development company is evaluating Amazon Q Developer to enhance its application development process by leveraging AI-driven tools for automation, code generation, and workflow optimization. The company is looking to understand t…
Answer: D. Amazon Q Developer can be used in integrated development environments (IDEs) as well as the AWS Management Console
Amazon Q Developer operates directly within integrated development environments and across the AWS Management Console to assist with coding and AWS queries. Do not assume it is restricted to just the IDE; it also provides architectural guidance directly inside the console dashboard.
Q16. A global e-commerce company is utilizing a foundation model through Amazon Bedrock to enhance its customer service chatbot, providing automated support and answering user queries. However, the company is concerned about the potential for t…
Answer: B. The company should instruct the model to stick to the prompt by adding explicit instructions to ignore any unrelated or potentially malicious content
Adding explicit instructions within the prompt is a straightforward prompt engineering technique to help guide model behavior and reject malicious inputs. However, for robust production workloads on Amazon Bedrock, implementing automated guardrails provides stronger content filtering than prompt instructions alone.
