NVIDIA Generative AI LLMs Sample Questions (Q16-Q21):

NEW QUESTION # 16
In the context of data preprocessing for Large Language Models (LLMs), what does tokenization refer to?

A. Converting text into numerical representations.
B. Applying data augmentation techniques to generate more training data.
C. Removing stop words from the text.
D. Splitting text into smaller units like words or subwords.

Answer: D

Explanation:
Tokenization is the process of splitting text into smaller units, such as words, subwords, or characters, which serve as the basic units for processing by LLMs. NVIDIA's NeMo documentation on NLP preprocessing explains that tokenization is a critical step in preparing text data, with popular tokenizers (e.g., WordPiece, BPE) breaking text into subword units to handle out-of-vocabulary words and improve model efficiency. For example, the sentence "I love AI" might be tokenized into ["I", "love", "AI"] or subword units like ["I",
"lov", "##e", "AI"]. Option B (numerical representations) refers to embedding, not tokenization. Option C (removing stop words) is a separate preprocessing step. Option D (data augmentation) is unrelated to tokenization.

NEW QUESTION # 17
In the context of developing an AI application using NVIDIA's NGC containers, how does the use of containerized environments enhance the reproducibility of LLM training and deployment workflows?

A. Containers reduce the model's memory footprint by compressing the neural network.
B. Containers automatically optimize the model's hyperparameters for better performance.
C. Containers encapsulate dependencies and configurations, ensuring consistent execution across systems.
D. Containers enable direct access to GPU hardware without driver installation.

Answer: C

Explanation:
NVIDIA's NGC (NVIDIA GPU Cloud) containers provide pre-configured environments for AI workloads, enhancing reproducibility by encapsulating dependencies, libraries, and configurations. According to NVIDIA's NGC documentation, containers ensure that LLM training and deployment workflows run consistently across different systems (e.g., local workstations, cloud, or clusters) by isolating the environment from host system variations. This is critical for maintaining consistent results in research and production.
Option A is incorrect, as containers do not optimize hyperparameters. Option C is false, as containers do not compress models. Option D is misleading, as GPU drivers are still required on the host system.

NEW QUESTION # 18
Which calculation is most commonly used to measure the semantic closeness of two text passages?

A. Cosine similarity
B. Jaccard similarity
C. Euclidean distance
D. Hamming distance

Answer: A

Explanation:
Cosine similarity is the most commonly used metric to measure the semantic closeness of two text passages in NLP. It calculates the cosine of the angle between two vectors (e.g., word embeddings or sentence embeddings) in a high-dimensional space, focusing on the direction rather than magnitude, which makes it robust for comparing semantic similarity. NVIDIA's documentation on NLP tasks, particularly in NeMo and embedding models, highlights cosine similarity as the standard metric for tasks like semantic search or text similarity, often using embeddings from models like BERT or Sentence-BERT. Option A (Hamming distance) is for binary data, not text embeddings. Option B (Jaccard similarity) is for set-based comparisons, not semantic content. Option D (Euclidean distance) is less common for text due to its sensitivity to vector magnitude.

NEW QUESTION # 19
What is the purpose of few-shot learning in prompt engineering?

A. To optimize hyperparameters
B. To fine-tune a model on a massive dataset
C. To train a model from scratch
D. To give a model some examples

Answer: D

Explanation:
Few-shot learning in prompt engineering involves providing a small number of examples (demonstrations) within the prompt to guide a large language model (LLM) to perform a specific task without modifying its weights. NVIDIA's NeMo documentation on prompt-based learning explains that few-shot prompting leverages the model's pre-trained knowledge by showing it a few input-output pairs, enabling it to generalize to new tasks. For example, providing two examples of sentiment classification in a prompt helps the model understand the task. Option B is incorrect, as few-shot learning does not involve training from scratch. Option C is wrong, as hyperparameter optimization is a separate process. Option D is false, as few-shot learning avoids large-scale fine-tuning.

NEW QUESTION # 20
Which model deployment framework is used to deploy an NLP project, especially for high-performance inference in production environments?

A. NVIDIA DeepStream
B. HuggingFace
C. NVIDIA Triton
D. NeMo

Answer: C

Explanation:
NVIDIA Triton Inference Server is a high-performance framework designed for deploying machine learning models, including NLP models, in production environments. It supports optimized inference on GPUs, dynamic batching, and integration with frameworks like PyTorch and TensorFlow. According to NVIDIA's Triton documentation, it is ideal for deploying LLMs for real-time applications with low latency. Option A (DeepStream) is for video analytics, not NLP. Option B (HuggingFace) is a library for model development, not deployment. Option C (NeMo) is for training and fine-tuning, not production deployment.
