20+ practice questions focused on Generative AI and Foundation Models — one of the most tested topics on the AWS Certified AI Practitioner AIF-C01 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Generative AI and Foundation Models PracticeA company wants to build a customer service chatbot that answers questions about their internal policy documents. The documents are updated monthly, and the team cannot afford to retrain a model each time. Which approach is MOST appropriate?
Explanation: RAG (Retrieval-Augmented Generation) allows the LLM to retrieve relevant document sections at inference time, so knowledge stays current without retraining. The other options either require expensive retraining for each update or lack document grounding.
Which component of the Transformer architecture allows the model to weigh the importance of different words in the input sequence when generating output?
Explanation: The self-attention mechanism computes attention scores between every pair of words in the input sequence, allowing the model to dynamically weigh the relevance of each word when producing an output. This enables the Transformer to capture long-range dependencies and contextual relationships, which is the core innovation over earlier sequence models like RNNs.
A data scientist is using Amazon Bedrock to generate product descriptions. They notice the output is often repetitive and lacks creativity. Which combination of parameter adjustments is MOST likely to produce more diverse and less repetitive output?
Explanation: Increasing temperature raises the probability of sampling lower-probability tokens, which increases randomness and diversity. Increasing top-p (nucleus sampling) expands the set of tokens considered for sampling, further reducing repetitiveness. Together, these adjustments encourage the model to explore a wider range of possible continuations, producing more creative and less repetitive output.
A developer is building a multimodal application that needs to process both text and images to generate a description. Which Amazon Bedrock model provider offers a multimodal foundation model capable of accepting images and text as input?
Explanation: Anthropic's Claude 3 and Claude 3.5 models on Amazon Bedrock are multimodal, accepting both text and image inputs to generate descriptions. This capability is built into the model's architecture, which processes images alongside text prompts natively, unlike other providers that focus solely on text or image generation.
A company is using Amazon Bedrock to generate embeddings for a semantic search application. They want to ensure that semantically similar phrases (e.g., "car" and "vehicle") produce similar vector representations. Which type of model should they use?
Explanation: Amazon Titan Embeddings is a text embedding model specifically designed to convert textual input into dense vector representations that capture semantic meaning. By mapping semantically similar phrases like 'car' and 'vehicle' to nearby points in the embedding space, it enables accurate similarity comparisons for semantic search applications.
