IBM watsonx Generative AI Engineer - Associate Sample Questions:

Question 1

You are developing a legal research assistant that uses Retrieval-Augmented Generation (RAG) to help lawyers find relevant case law. The system must provide case law that is not only relevant to the query but also semantically similar in meaning to the legal terminology used.
Given this scenario, which of the following retrievers would be the most appropriate choice for this application?

A. A sparse retriever based on keyword matching and BM25 algorithm.
B. A rule-based retriever optimized for simple, pre-defined keyword mappings.
C. A sparse retriever that integrates exact matching of legal terms with synonym matching.
D. A dense retriever based on embeddings from a fine-tuned BERT model.

Question 2

You are tasked with deploying a foundation model for text generation on the IBM Watsonx platform. The foundation model has been pre-trained on a large corpus but has not been fine-tuned for your specific use case.
What is the most critical factor to consider when deploying this model to ensure it performs optimally on the Watsonx platform?

A. You must ensure that the model is compatible with IBM's foundation model API, as Watsonx only allows deployment of models that integrate with its foundation model architecture.
B. The model should be fine-tuned with domain-specific data before deployment, as Watsonx requires fine-tuning for all foundation models before they can be deployed.
C. You should enable quantization of the model to optimize inference performance without compromising accuracy in a production environment.
D. The model's size should be reduced to fit within the memory constraints of the deployment environment, even if it leads to a loss of precision in its outputs.

Question 3

You are working on optimizing a large language model (LLM) using quantization techniques. Your goal is to reduce memory usage while maintaining as much of the model's original accuracy as possible.
What is a common challenge faced when applying quantization to LLMs, and how can it be mitigated?

A. Embedding layers in LLMs are difficult to quantize, so it's best to skip quantization for these layers entirely.
B. Quantization causes a drastic reduction in training time, but increases memory usage. Use sparse quantization to address this.
C. Quantization may cause a significant drop in model accuracy, especially in embedding layers. Using quantization-aware training can help mitigate this.
D. LLMs are inherently resistant to quantization, so switching to a smaller model architecture is the only viable solution.

Question 4

Which of the following best describes the effect of controlling model parameters during the decoding process in IBM Watsonx's generative AI models?

A. Controlling model parameters allows the model to generate only the shortest possible responses, ensuring concise outputs.
B. Model parameters control the model's ability to self-learn from previous outputs, improving its performance over time.
C. Setting model parameters guarantees that the model will generate the most grammatically correct response, regardless of context.
D. Adjusting model parameters helps control the randomness in the output generation process, enabling a balance between creativity and accuracy.

Question 5

You are optimizing a generative AI chatbot for concise responses to user queries, ensuring that it doesn't over-generate unnecessary content. However, you observe that the model occasionally stops prematurely, cutting off relevant information.
What configuration best addresses this issue without allowing for excessive output?

A. Stop Sequence = '.', Max Tokens = 500
B. Stop Sequence = '</end>', Max Tokens = 250
C. Stop Sequence = '.' (period followed by a space), Max Tokens = 300
D. Stop Sequence = '.', Max Tokens = 150
