1Which IBM-developed family of foundation models is available natively on watsonx.ai and is positioned as IBM's enterprise-grade option?

A.Granite

B.Llama 2

C.Mistral

D.Falcon

Explanation: IBM Granite is the family of foundation models developed by IBM Research and offered as enterprise-ready models on watsonx.ai. Granite models are trained on curated, indemnified data and come in chat, code, and instruct variants designed for business workloads.

2A developer wants to interactively craft and test prompts against a foundation model on watsonx.ai before embedding the prompt into an application. Which watsonx.ai tool is designed for this?

A.Prompt Lab

B.Tuning Studio

C.Watson OpenScale

D.AutoAI

Explanation: Prompt Lab is the watsonx.ai workspace where users craft, test, and iterate on prompts against foundation models in chat, freeform, or structured modes. It supports saving prompts as session assets or deploying them as prompt templates.

3Which decoding parameter most directly controls the randomness of token selection during text generation, where a higher value increases creativity?

A.Max new tokens

B.Stop sequences

C.Temperature

D.Repetition penalty

Explanation: Temperature scales the logits before the softmax during sampling. Higher temperature (>1) flattens the distribution and yields more diverse, creative output; lower temperature (<1) sharpens it toward the highest-probability token. It is the primary 'creativity' knob in sampling decoding.

4A team is building a chatbot that must answer questions about an internal HR policy PDF that the foundation model has never seen. Which approach is most appropriate?

A.Pre-train a new foundation model from scratch

B.Use Retrieval-Augmented Generation (RAG) with a vector store

C.Increase the temperature of the existing model

D.Add the entire PDF to every system prompt

Explanation: RAG retrieves relevant policy chunks from a vector store at query time and injects them into the prompt as grounded context. This lets the model answer with up-to-date proprietary knowledge without retraining and without exceeding the context window for unrelated content.

5In the context of large language models, what is a 'token'?

A.A single character

B.A subword unit produced by the model's tokenizer

C.A complete sentence

D.A hexadecimal hash of the prompt

Explanation: A token is the unit of text consumed and produced by an LLM. Modern tokenizers (BPE, SentencePiece, etc.) split text into subword pieces — common words may be one token, rare words multiple tokens. Token counts drive context-window limits and pricing.

6Which prompting technique provides the model a few input/output examples in the prompt itself to demonstrate the desired pattern?

A.Zero-shot prompting

B.Few-shot prompting

C.Prompt tuning

D.Fine-tuning

Explanation: Few-shot prompting includes a small number of solved examples directly in the prompt so the model can pattern-match the format and reasoning. It requires no model weights to change and is the fastest way to steer behavior on novel tasks.

7Which watsonx component is the data lakehouse that supports open table formats such as Apache Iceberg and engines including Presto and Spark?

A.watsonx.ai

B.watsonx.data

C.watsonx.governance

D.watsonx.assistant

Explanation: watsonx.data is IBM's open data lakehouse for AI and analytics workloads. It uses Apache Iceberg as its primary open table format and exposes data through Presto (interactive SQL) and Spark (batch/ML), letting teams query data in place across object stores and warehouses.

8Which watsonx product provides model lifecycle governance, including model facts sheets, bias monitoring, and drift detection?

A.watsonx.ai

B.watsonx.data

C.watsonx.governance

D.watsonx Code Assistant

Explanation: watsonx.governance manages AI risk and compliance across the model lifecycle. It produces auto-generated AI factsheets, monitors fairness/bias, detects drift, and tracks regulatory requirements such as the EU AI Act in a single inventory.

9Which of the following is a generative AI use case rather than a discriminative one?

A.Classifying an email as spam or not spam

B.Predicting whether a customer will churn

C.Drafting a personalized customer support reply from an issue summary

D.Detecting fraudulent transactions

Explanation: Generative AI produces new content — text, images, code — conditioned on input. Drafting a personalized reply creates novel text, making it generative. The other options are classification tasks that assign labels rather than create content.

10What is the purpose of an embedding model in a RAG pipeline?

A.Convert text into dense numerical vectors so similar meanings are close in vector space

B.Generate the final natural-language answer for the user

C.Encrypt data before it is stored in the vector database

D.Compress the foundation model to fit on edge devices

Explanation: Embedding models map text into dense vectors such that semantically similar passages are close in vector space (commonly measured by cosine similarity). The vector store then performs nearest-neighbor search to find relevant chunks for retrieval.
