AIF-C01 Exam Dumps - Amazon Web Services AWS Certified AI Practitioner Questions and Answers

Amazon SageMaker Canvas is a visual, no-code tool for building and deploying ML models. According to the official SageMaker Canvas documentation:

“SageMaker Canvas provides a visual point-and-click interface that allows business analysts to generate accurate ML predictions without writing any code.”

Amazon SageMaker Unified Studio provides a collaborative, secure, and centralized environment for end-to-end data, machine learning, and generative AI development. AWS documentation describes Unified Studio as a single interface where teams can prepare data, build models, train and deploy machine learning solutions, and develop generative AI applications.

In this use case, multiple teams must collaborate in a shared environment. SageMaker Unified Studio supports role-based access control, shared workspaces, and secure resource management, allowing developers to safely collaborate without compromising data or models. AWS highlights that Unified Studio integrates notebooks, pipelines, model development tools, and generative AI workflows into a consistent experience.

The service also supports model sharing, versioning, and reuse, enabling teams to build upon each other’s work. This directly satisfies the requirement to build and share both traditional ML models and generative AI applications securely.

The other options are not suitable. Amazon Lex is a conversational AI service, not a development environment. Amazon Bedrock PartyRock is a no-code generative AI playground and is not intended for enterprise collaboration. Amazon Q Developer focuses on developer productivity and code assistance, not unified AI development environments.

AWS positions SageMaker Unified Studio as the foundation for collaborative AI development at scale, making it the correct choice.

The correct answer is Amazon Bedrock PartyRock, a playground for building and experimenting with generative AI apps in a low-cost, no-code environment. PartyRock is designed for innovation and learning. It enables users to try out prompts, LLM apps, and templates using Amazon Bedrock under a free-tier friendly setup. According to AWS, PartyRock abstracts infrastructure and allows rapid prototyping using models from Bedrock providers. This makes it ideal for early experimentation, especially for non-developers or those not ready to invest in full production pipelines. In contrast, Amazon Q Developer is for software engineering tasks, SageMaker JumpStart focuses on deploying ML models, and Q Business targets enterprise knowledge workers. None of those are as cost-effective and experimental-focused as PartyRock.

AWS Generative AI Learning Path – Getting Started Tools

To use a custom model that has been trained to improve summarization quality, the company must deploy the model on an Amazon SageMaker endpoint. This allows the model to be used for real-time inference through Amazon Bedrock or other AWS services. By deploying the model in SageMaker, the custom model can be accessed programmatically via API calls, enabling integration with Amazon Bedrock.

Option B (Correct): "Deploy the custom model in an Amazon SageMaker endpoint for real-time inference": This is the correct answer because deploying the model on SageMaker enables it to serve real-time predictions and be integrated with Amazon Bedrock.

Option A: "Purchase Provisioned Throughput for the custom model" is incorrect because provisioned throughput is related to database or storage services, not model deployment.

Option C: "Register the model with the Amazon SageMaker Model Registry" is incorrect because while the model registry helps with model management, it does not make the model accessible for real-time inference.

Option D: "Grant access to the custom model in Amazon Bedrock" is incorrect because Bedrock does not directly manage custom model access; it relies on deployed endpoints like those in SageMaker.

AWS AI Practitioner References:

Amazon SageMaker Endpoints: AWS recommends deploying models to SageMaker endpoints to use them for real-time inference in various applications.

When a model performs well on the training data but poorly in production, it is often due to overfitting. Overfitting occurs when a model learns patterns and noise specific to the training data, which does not generalize well to new, unseen data in production. Increasing the volume of data used in training can help mitigate this problem by providing a more diverse and representative dataset, which helps the model generalize better.

Option C (Correct): "Increase the volume of data that is used in training": Increasing the data volume can help the model learn more generalized patterns rather than specific features of the training dataset, reducing overfitting and improving performance in production.

Option A: "Reduce the volume of data that is used in training" is incorrect, as reducing data volume would likely worsen the overfitting problem.

Option B: "Add hyperparameters to the model" is incorrect because adding hyperparameters alone does not address the issue of data diversity or model generalization.

Option D: "Increase the model training time" is incorrect because simply increasing training time does not prevent overfitting; the model needs more diverse data.

AWS AI Practitioner References:

Best Practices for Model Training on AWS: AWS recommends using a larger and more diverse training dataset to improve a model's generalization capability and reduce the risk of overfitting.

Comprehensive and Detailed Explanation From Exact AWS AI documents:

Generative AI models offer adaptability, meaning they can generalize across:

Different markets

New product lines

Variations in language and complaint structure

Unlike hard-coded logic, generative models can adapt to new patterns and inputs without requiring extensive rule rewrites, making them ideal for scaling text-based processing applications.

Why the other options are incorrect:

Predictability (A) is typically lower in generative models.

Less sensitivity (C) is incorrect; generative models are sensitive to input variations.

Explainability (D) is generally limited in large generative models.

Generative AI Benefits and Trade-offs

Modernizing Text Processing with Foundation Models

Scaling NLP Solutions on AWS

 Sentiment analysis → Text data

 Traffic sign recognition → Image data

 Customer demographics & purchase history → Tabular data

 Stock price forecasting → Time series data

 AWS classifies NLP tasks like sentiment analysis under text data

 Computer vision tasks such as object and sign recognition use image data

 Structured rows and columns (demographics, transactions) are tabular data

 Sequential data indexed by time (prices, metrics) is time series data

The business objective to evaluate the effect of an LLM chatbot aimed at reducing the actions required by call center employees should be average call duration.

Average Call Duration:

This metric measures the time taken to handle a customer call or query. A successful LLM chatbot should reduce the call duration by efficiently providing answers, minimizing the need for human intervention.

By decreasing the average call duration, the company can improve call center efficiency, reduce costs, and enhance the user experience.

Why Option B is Correct:

Direct Impact: The objective aligns directly with the goal of reducing the number of actions call center employees must take.

Operational Efficiency: Reducing call duration is a clear indicator of the chatbot's effectiveness in assisting customers without human help.

Why Other Options are Incorrect:

A. Website engagement rate: Is unrelated to call center operations.

C. Corporate social responsibility: Does not relate to call center efficiency.

D. Regulatory compliance: Is important but does not measure the effectiveness of a chatbot in reducing employee actions.

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.

Prompt Engineering:

Adjusting and refining the prompt allows for better control over the FM's outputs, ensuring they align with the desired tone and style.

This iterative process involves testing different prompts and modifying them based on the model's responses to achieve the desired outcome.

Why Option C is Correct:

Directly Influences Output Quality: Allows for fine-tuning of the model’s responses to match the company's tone.

Cost-Effective: Does not require modifying the model itself, only the inputs to it.

Why Other Options are Incorrect:

A. Low limit on tokens: Limits response length but not the adherence to company tone.

B. Batch inferencing: Relates to processing multiple inputs, not controlling response tone.

D. Higher temperature: Increases randomness in responses, which could deviate from the desired tone.
