Amazon Web Services AIF-C01 Exam With Confidence Using Practice Dumps

Providing labeled data with both a prompt field and a completion field is the correct strategy for fine-tuning a foundation model (FM) on Amazon Bedrock.

Fine-Tuning Strategy:

To fine-tune a model, labeled data that pairs input prompts with the correct outputs (completions) is necessary.

This allows the model to learn the desired behavior or response style based on the provided examples.

Why Option A is Correct:

Proper Training Format: The prompt-completion pairs provide the necessary format for training the model to produce accurate outputs.

Customization: Ensures that the model is fine-tuned to the specific requirements of the company’s data and desired outputs.

Why Other Options are Incorrect:

B. Prepare a .txt file in .csv format: This does not align with the specific need for labeled data with prompts and completions.

C. Purchase Provisioned Throughput: Relates to read/write capacity in databases, not to model fine-tuning.

D. Train on journals and textbooks: Lacks the specific format and labeling required for fine-tuning.

Amazon Textract is a service that automatically extracts text and data from scanned documents, including PDFs. It is the best choice for converting resumes from PDF format to plain text for further processing.

Amazon Textract:

Extracts text, forms, and tables from scanned documents accurately.

Ideal for automating the process of converting PDF resumes into plain text format.

Why Option A is Correct:

Automation of Text Extraction: Textract is designed to handle large volumes of documents and convert them into machine-readable text, perfect for the company's need.

Scalability and Efficiency: Supports scalability to handle a growing volume of resumes as the company expands.

Why Other Options are Incorrect:

B. Amazon Personalize: Used for creating personalized recommendations, not for text extraction.

C. Amazon Lex: A service for building conversational interfaces, not for processing documents.

D. Amazon Transcribe: Used for converting speech to text, not for extracting text from documents.

Generative adversarial networks (GANs) are a type of deep learning model used for generating synthetic data based on existing datasets. GANs consist of two neural networks (a generator and a discriminator) that work together to create realistic data.

Option A (Correct): "Generative adversarial network (GAN)": This is the correct answer because GANs are specifically designed for generating synthetic data that closely resembles the real data they are trained on.

Option B: "XGBoost" is a gradient boosting algorithm for classification and regression tasks, not for generating synthetic data.

Option C: "Residual neural network" is primarily used for improving the performance of deep networks, not for generating synthetic data.

Option D: "WaveNet" is a model architecture designed for generating raw audio waveforms, not synthetic data in general.
