NVIDIA Generative AI LLMs Sample Questions (Q12-Q17):
NEW QUESTION # 12
In Natural Language Processing, there are a group of steps in problem formulation collectively known as word representations (also word embeddings). Which of the following are Deep Learning models that can be used to produce these representations for NLP tasks? (Choose two.)
- A. WordNet
- B. TensorRT
- C. Word2vec
- D. Kubernetes
- E. BERT
Answer: C,E
Explanation:
Word representations, or word embeddings, are critical in NLP for capturing semantic relationships between words, as emphasized in NVIDIA's Generative AI and LLMs course. Word2vec and BERT are deep learning models designed to produce these embeddings. Word2vec uses shallow neural networks (CBOW or Skip- Gram) to generate dense vector representations based on word co-occurrence in a corpus, capturing semantic similarities. BERT, a Transformer-based model, produces contextual embeddings by considering bidirectional context, making it highly effective for complex NLP tasks. Option B, WordNet, is incorrect, as it is a lexical database, not a deep learning model. Option C, Kubernetes, is a container orchestration platform, unrelated to NLP or embeddings. Option D, TensorRT, is an inference optimization library, not a model for embeddings.
The course notes: "Deep learning models like Word2vec and BERT are used to generate word embeddings, enabling semantic understanding in NLP tasks, with BERT leveraging Transformer architectures for contextual representations."

NEW QUESTION # 13
Which of the following is a parameter-efficient fine-tuning approach that one can use to fine-tune LLMs in a memory-efficient fashion?
- A. TensorRT
- B. Chinchilla
- C. LoRA
- D. NeMo
Answer: C
Explanation:
LoRA (Low-Rank Adaptation) is a parameter-efficient fine-tuning approach specifically designed for large language models (LLMs), as covered in NVIDIA's Generative AI and LLMs course. It fine-tunes LLMs by updating a small subset of parameters through low-rank matrix factorization, significantly reducing memory and computational requirements compared to full fine-tuning. This makes LoRA ideal for adapting large models to specific tasks while maintaining efficiency. Option A, TensorRT, is incorrect, as it is an inference optimization library, not a fine-tuning method. Option B, NeMo, is a framework for building AI models, not a specific fine-tuning technique. Option C, Chinchilla, is a model, not a fine-tuning approach. The course emphasizes: "Parameter-efficient fine-tuning methods like LoRA enable memory-efficient adaptation of LLMs by updating low-rank approximations of weight matrices, reducing resource demands while maintaining performance." References: NVIDIA Building Transformer-Based Natural Language Processing Applications course; NVIDIA Introduction to Transformer-Based Natural Language Processing.
NEW QUESTION # 14
In the context of a natural language processing (NLP) application, which approach is most effective for implementing zero-shot learning to classify text data into categories that were not seen during training?
- A. Use a pre-trained language model with semantic embeddings.
- B. Use a large, labeled dataset for each possible category.
- C. Train the new model from scratch for each new category encountered.
- D. Use rule-based systems to manually define the characteristics of each category.
Answer: A
Explanation:
Zero-shot learning allows models to perform tasks or classify data into categories without prior training on those specific categories. In NLP, pre-trained language models (e.g., BERT, GPT) with semantic embeddings are highly effective for zero-shot learning because they encode general linguistic knowledge and can generalize to new tasks by leveraging semantic similarity. NVIDIA's NeMo documentation on NLP tasks explains that pre-trained LLMs can perform zero-shot classification by using prompts or embeddings to map input text to unseen categories, often via techniques like natural language inference or cosine similarity in embedding space. Option A (rule-based systems) lacks scalability and flexibility. Option B contradicts zero- shot learning, as it requires labeled data. Option C (training from scratch) is impractical and defeats the purpose of zero-shot learning.

NEW QUESTION # 15
"Hallucinations" is a term coined to describe when LLM models produce what?
- A. Images from a prompt description.
- B. Outputs are only similar to the input data.
- C. Grammatically incorrect or broken outputs.
- D. Correct sounding results that are wrong.
Answer: D
Explanation:
In the context of LLMs, "hallucinations" refer to outputs that sound plausible and correct but are factually incorrect or fabricated, as emphasized in NVIDIA's Generative AI and LLMs course. This occurs when models generate responses based on patterns in training data without grounding in factual knowledge, leading to misleading or invented information. Option A is incorrect, as hallucinations are not about similarity to input data but about factual inaccuracies. Option B is wrong, as hallucinations typically refer to text, not image generation. Option D is inaccurate, as hallucinations are grammatically coherent but factually wrong. The course states: "Hallucinations in LLMs occur when models produce correct-sounding but factually incorrect outputs, posing challenges for ensuring trustworthy AI." References: NVIDIA Building Transformer-Based Natural Language Processing Applications course; NVIDIA Introduction to Transformer-Based Natural Language Processing.
NEW QUESTION # 16
You have access to training data but no access to test data. What evaluation method can you use to assess the performance of your AI model?
- A. Average entropy approximation
- B. Cross-validation
- C. Greedy decoding
- D. Randomized controlled trial
Answer: B
Explanation:
When test data is unavailable, cross-validation is the most effective method to assess an AI model's performance using only the training dataset. Cross-validation involves splitting the training data into multiple subsets (folds), training the model on some folds, and validating it on others, repeating this process to estimate generalization performance. NVIDIA's documentation on machine learning workflows, particularly in the NeMo framework for model evaluation, highlights k-fold cross-validation as a standard technique for robust performance assessment when a separate test set is not available. Option B (randomized controlled trial) is a clinical or experimental method, not typically used for model evaluation. Option C (average entropy approximation) is not a standard evaluation method. Option D (greedy decoding) is a generation strategy for LLMs, not an evaluation technique.
