NVIDIA Generative AI LLMs Sample Questions (Q85-Q90):NEW QUESTION # 85
Which of the following claims is correct about quantization in the context of Deep Learning? (Pick the 2 correct responses)

A. It only involves reducing the number of bits of the parameters.
B. It leads to a substantial loss of model accuracy.
C. Helps reduce memory requirements and achieve better cache utilization.
D. It consists of removing a quantity of weights whose values are zero.
E. Quantization might help in saving power and reducing heat production.

Answer: C,E
Explanation:
Quantization in deep learning involves reducing the precision of model weights and activations (e.g., from 32- bit floating-point to 8-bit integers) to optimize performance. According to NVIDIA's documentation on model optimization and deployment (e.g., TensorRT and Triton Inference Server), quantization offers several benefits:
* Option A: Quantization reduces power consumption and heat production by lowering the computational intensity of operations, making it ideal for edge devices.

NEW QUESTION # 86
What is the purpose of the NVIDIA NeMo Toolkit?

A. NeMo helps researchers develop state-of-the-art models for computer vision based on convolutions.
B. NeMo focuses on the morphology of a language by studying its words, and how they are formed.
C. NeMo helps researchers to develop models that trade-off size with minimum loss impact.
D. NeMo facilitates the creation of models for speech recognition and natural language understanding.

Answer: D
Explanation:
The NVIDIA NeMo Toolkit is a scalable, open-source framework designed to facilitate the development of state-of-the-art conversational AI models, particularly for Automatic Speech Recognition (ASR), Natural Language Processing (NLP), and Text-to-Speech (TTS). As highlighted in NVIDIA's Generative AI and LLMs course, NeMo provides modular, pre-built components and pre-trained models that researchers and developers can customize and fine-tune for tasks like speech recognition and natural language understanding.
It supports multi-GPU and multi-node training, leveraging PyTorch for efficient model development. Option A is incorrect, as NeMo does not focus on language morphology but on building AI models. Option B is wrong, as NeMo's primary goal is not model size trade-offs but comprehensive conversational AI development. Option D is inaccurate, as NeMo primarily targets speech and language tasks, not computer vision. The course notes: "NVIDIA NeMo is a toolkit for building conversational AI models, including Automatic Speech Recognition (ASR), Natural Language Processing (NLP), and Text-to-Speech (TTS) models, enabling researchers to create and deploy advanced AI solutions."

NEW QUESTION # 87
Which metric is primarily used to evaluate the quality of the text generated by language models?

A. Perplexity
B. Recall
C. Precision
D. Accuracy

Answer: A
Explanation:
Perplexity is the primary metric used to evaluate the quality of text generated by language models, as emphasized in NVIDIA's Generative AI and LLMs course. Perplexity measures how well a language model predicts a sequence of tokens, with lower values indicating better performance, as the model is less
"surprised" by the data. It is calculated as the exponentiated average negative log-likelihood of the tokens in a test set, reflecting the model's ability to assign high probabilities to correct sequences. In generative tasks, perplexity is widely used because it directly assesses the model's fluency and coherence. Option B, Precision, and Option C, Recall, are metrics for classification tasks, not text generation. Option D, Accuracy, is also irrelevant for evaluating generative quality, as it applies to categorical predictions. The course notes:
"Perplexity is a key metric for evaluating language models, measuring how well the model predicts text sequences, with lower perplexity indicating higher-quality generation." References: NVIDIA Building Transformer-Based Natural Language Processing Applications course; NVIDIA Introduction to Transformer-Based Natural Language Processing.

NEW QUESTION # 88
What are the main advantages of instructed large language models over traditional, small language models (<
300M parameters)? (Pick the 2 correct responses)

A. It is easier to explain the predictions.
B. Single generic model can do more than one task.
C. Smaller latency, higher throughput.
D. Cheaper computational costs during inference.
E. Trained without the need for labeled data.

Answer: B,D
Explanation:
Instructed large language models (LLMs), such as those supported by NVIDIA's NeMo framework, have significant advantages over smaller, traditional models:
* Option D: LLMs often have cheaper computational costs during inference for certain tasks because they can generalize across multiple tasks without requiring task-specific retraining, unlike smaller models that may need separate models per task.

NEW QUESTION # 89
When comparing and contrasting the ReLU and sigmoid activation functions, which statement is true?

A. ReLU is less computationally efficient than sigmoid, but it is more accurate than sigmoid.
B. ReLU is more computationally efficient, but sigmoid is better for predicting probabilities.
C. ReLU and sigmoid both have a range of 0 to 1.
D. ReLU is a linear function while sigmoid is non-linear.

Answer: B
Explanation:
ReLU (Rectified Linear Unit) and sigmoid are activation functions used in neural networks. According to NVIDIA's deep learning documentation (e.g., cuDNN and TensorRT), ReLU, defined as f(x) = max(0, x), is computationally efficient because it involves simple thresholding, avoiding expensive exponential calculations required by sigmoid, f(x) = 1/(1 + e
