QUESTION NO: 4
You want a generative AI model to summarize a lengthy text in one sentence. You provide the following prompt: "Summarize the following paragraph in one sentence: 'Artificial intelligence (AI) is the simulation of human intelligence in machines that are programmed to think and learn. The field of AI includes everything from speech recognition to problem-solving and robotics.'" No prior examples are given.
What type of prompting is being used, and what are the expectations?

A. Zero-shot prompting, with the expectation that the model can summarize common concepts like AI due to pre-training. B. Few-shot prompting, but the model will likely struggle without a few examples of summaries provided. C. Zero-shot prompting, but it requires the addition of a few examples for the model to generate a summary. D. Zero-shot prompting, but the model may fail without detailed instructions on what aspects of the text to focus on.

Correct Answer: A

QUESTION NO: 5
You are creating a prompt template for a generative AI model that helps technical support staff troubleshoot customer issues based on symptoms provided. The goal is to generate a clear, step-by-step diagnostic process.
What elements would improve the effectiveness of the template? (Select two)

A. Provide explicit instructions to break the response into steps B. Incorporate complex technical jargon to ensure expert-level responses C. Include an instruction to ask clarifying questions when the issue is unclear D. Ask the model to generate multiple diagnostic paths for each issue E. Set a high temperature value to explore more creative diagnostic approaches

Correct Answer: A,C

QUESTION NO: 6
You are working on a Retrieval-Augmented Generation (RAG) system using IBM watsonx. The system needs to retrieve relevant documents based on a user's query and generate a response using a language model. To optimize retrieval, you are tasked with generating vector embeddings for documents and queries using a pre-trained model. Your goal is to ensure that the embeddings are semantically meaningful to improve the retrieval accuracy.
Which of the following steps should be taken to ensure the vector embeddings are correctly generated and effective for document retrieval in a RAG system? (Select two)

A. Normalize the vector embeddings after generation to ensure they are comparable during retrieval. B. Manually adjust the embedding vectors to emphasize certain keywords that are more important for retrieval. C. Generate embeddings for documents only and skip embeddings for user queries, relying on traditional keyword-based retrieval for queries. D. Use a generative language model to generate embeddings without any fine-tuning, as it captures all the necessary context. E. Use a pre-trained model designed specifically for embedding generation rather than general-purpose language models.

Correct Answer: A,E

QUESTION NO: 7
When working with IBM Watsonx Generative AI models, it's important to configure proper stopping criteria to control when the model should terminate the text generation process. You are developing a chatbot where responses should stay within a manageable length without losing coherence.
Which configuration best represents an effective stopping criterion to ensure coherent responses without abrupt truncation?

A. Greedy decoding with maximum tokens set to 20 and a stop sequence of "END". B. Greedy decoding with no stop sequence and maximum tokens set to 200. C. Beam search decoding with a stop sequence of "END" and a maximum tokens limit of 50. D. Greedy decoding with temperature set to 2.0 and no stop sequence.

Correct Answer: C

QUESTION NO: 8

QUESTION NO: 9
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.
