Question 2

In the context of a Retrieval-Augmented Generation (RAG) system, which type of retriever is best suited for retrieving documents based on semantic similarity in a vector space?

A. Hierarchical retriever, which first applies keyword-based filters and then ranks documents using machine learning models. B. Exact match retriever, which retrieves documents that exactly match the query string. C. Boolean retriever, which uses logical operators (AND, OR, NOT) to filter documents based on keyword presence. D. Dense retriever, which converts both the query and documents into vectors and retrieves based on similarity in the vector space.

Question 5

Your team has developed an AI model that generates automated legal documents based on user inputs. The client, a large law firm, wants to deploy this model but has stringent security, compliance, and auditability requirements due to the sensitive nature of the data.
What is the most appropriate deployment strategy to meet these specific requirements?

A. Deploy the model on a hybrid cloud, with inference done on the client's on-premise servers and training done in the public cloud. B. Deploy the model using a serverless architecture to minimize operational overhead and maintain compliance. C. Use a private cloud with role-based access controls (RBAC) and ensure model activity is logged for auditing purposes. D. Deploy the model on a public cloud with built-in encryption and use APIs to connect to the client's private data.

Question 6

You are working on a large-scale enterprise application using IBM watsonx and need to ensure that different versions of your generative AI model prompts are properly managed for deployment.
Which of the following is the most appropriate action when planning the deployment of prompt versions?

A. Embed the prompt version directly into the API request body so that the deployed model can select the correct prompt dynamically at runtime. B. Store all prompt versions directly in the model's code repository, updating the main branch with each new version. C. Keep prompt versions in an external document management system and manually track which versions are deployed in the application. D. Use a deployment space in IBM watsonx to version your prompts, assigning unique tags to each version and ensuring rollback capabilities.

Question 7

You are experimenting with a generative AI model to write a personalized email response template. You want to ensure that the output maintains a formal tone but occasionally produces creative phrasing without making nonsensical sentences. You are advised to adjust the top-p (nucleus sampling) parameter.
Which of the following settings would most effectively balance between formal coherence and occasional creativity in the generated output?

A. Set top-p to 0.5 B. Set top-p to 0.95 C. Set top-p to 0.0 D. Set top-p to 1.0

Question 8

You are designing a workflow using watsonx.ai to generate complex text summaries from multiple sources. To achieve this, you plan to implement a LangChain-based chain that orchestrates different generative AI tasks: document retrieval, natural language processing (NLP) analysis, and summarization.
What is the best way to structure the LangChain-based chain to ensure that each task is effectively handled and results in an accurate summary?

A. Start with NLP analysis, pass the data to watsonx.ai for summarization, and then perform document retrieval to verify the accuracy of the summary. B. Use watsonx.ai to generate a summary immediately, and then perform NLP analysis and document retrieval in parallel to verify the accuracy of the output. C. Perform document retrieval first, followed by NLP analysis to extract relevant information, and then pass the processed data to watsonx.ai for summarization. D. Break the LangChain-based chain into individual steps that allow for manual intervention at each stage, ensuring control over the process at every step.

Question 9

You are working on generating synthetic training data using IBM InstructLab to supplement a small dataset for a question-answering system.
Which strategy would most effectively enhance the dataset without introducing biases or artifacts?

A. Use prompts that closely mimic the structure and semantics of the real dataset's questions to maintain consistency. B. Manually tweak each generated response to ensure it's free of errors and aligns with the intended task. C. Generate a large amount of synthetic data by directly feeding the model with random prompts, ensuring data diversity. D. Automatically generate synthetic data using a different model architecture than the one being fine-tuned.

Question 10

You are building a customer support chatbot using IBM watsonx.ai and Watson Assistant. The chatbot must use watsonx.ai's large language model (LLM) to generate dynamic responses and Watson Assistant to manage dialog and interaction flow.
What is the most efficient way to integrate these two services to deliver an optimal solution?

A. Deploy watsonx.ai's LLM within Watson Assistant by embedding the LLM directly into the Watson Assistant environment. B. Use Watson Assistant as the primary interface and call watsonx.ai's LLM through an API for generating dynamic responses in specific intents. C. Build a separate microservice for each service, allowing Watson Assistant and watsonx.ai's LLM to operate independently, with no communication between them. D. Use Watson Assistant to directly generate all responses, bypassing watsonx.ai's LLM.

Question 11

In the context of IBM Watsonx and generative AI models, you are tasked with designing a model that needs to classify customer support tickets into different categories. You decide to experiment with both zero-shot and few-shot prompting techniques.
Which of the following best explains the key difference between zero-shot and few-shot prompting?

A. Few-shot prompting is used only for training the model, while zero-shot prompting is used only for inference tasks. B. In zero-shot prompting, the model learns from a large number of examples during the inference stage, while in few-shot prompting, only a single example is used. C. Zero-shot prompting does not use any examples in the input prompt, while few-shot prompting includes a few examples to guide the model. D. Zero-shot prompting provides the model with a few example tasks to help it understand the problem, while few-shot prompting provides no examples at all.

Question 12

You are designing a customer support chatbot using watsonx.ai as the primary generative model. You want to enhance the chatbot's capabilities by integrating it with IBM Watson Assistant to handle structured conversations while allowing watsonx.ai to generate responses for open-ended queries.

A. Use Watson Discovery to preprocess all queries before routing them to either Watson Assistant or watsonx.ai based on query complexity. B. Implement Watson Assistant for structured conversations and use a middleware layer that dynamically routes complex, open-ended queries to watsonx.ai, returning the results within the same session. C. Create separate chat interfaces for Watson Assistant and watsonx.ai, and allow the user to choose which system to query based on their needs. D.
