NVIDIA Generative AI LLMs Sample Questions (Q26-Q31):

NEW QUESTION # 26
You have developed a deep learning model for a recommendation system. You want to evaluate the performance of the model using A/B testing. What is the rationale for using A/B testing with deep learning model performance?

  • A. A/B testing allows for a controlled comparison between two versions of the model, helping to identify the version that performs better.
  • B. A/B testing ensures that the deep learning model is robust and can handle different variations of input data.
  • C. A/B testing helps in collecting comparative latency data to evaluate the performance of the deep learning model.
  • D. A/B testing methodologies integrate rationale and technical commentary from the designers of the deep learning model.

Answer: A

Explanation:
A/B testing is a controlled experimentation method used to compare two versions of a system (e.g., two model variants) to determine which performs better based on a predefined metric (e.g., user engagement, accuracy).
NVIDIA's documentation on model optimization and deployment, such as with Triton Inference Server, highlights A/B testing as a method to validate model improvements in real-world settings by comparing performance metrics statistically. For a recommendation system, A/B testing might compare click-through rates between two models. Option B is incorrect, as A/B testing focuses on outcomes, not designer commentary. Option C is misleading, as robustness is tested via other methods (e.g., stress testing). Option D is partially true but narrow, as A/B testing evaluates broader performance metrics, not just latency.

NEW QUESTION # 27
Which of the following is a key characteristic of Rapid Application Development (RAD)?

  • A. Linear progression through predefined project phases.
  • B. Iterative prototyping with active user involvement.
  • C. Extensive upfront planning before any development.
  • D. Minimal user feedback during the development process.

Answer: B

Explanation:
Rapid Application Development (RAD) is a software development methodology that emphasizes iterative prototyping and active user involvement to accelerate development and ensure alignment with user needs.
NVIDIA's documentation on AI application development, particularly in the context of NGC (NVIDIA GPU Cloud) and software workflows, aligns with RAD principles for quickly building and iterating on AI-driven applications. RAD involves creating prototypes, gathering user feedback, and refining the application iteratively, unlike traditional waterfall models. Option B is incorrect, as RAD minimizes upfront planning in favor of flexibility. Option C describes a linear waterfall approach, not RAD. Option D is false, as RAD relies heavily on user feedback.

NEW QUESTION # 28
When deploying an LLM using NVIDIA Triton Inference Server for a real-time chatbot application, which optimization technique is most effective for reducing latency while maintaining high throughput?

  • A. Switching to a CPU-based inference engine for better scalability.
  • B. Increasing the model's parameter count to improve response quality.
  • C. Reducing the input sequence length to minimize token processing.
  • D. Enabling dynamic batching to process multiple requests simultaneously.

Answer: D

Explanation:
NVIDIA Triton Inference Server is designed for high-performance model deployment, and dynamicbatching is a key optimization technique for reducing latency while maintaining high throughput in real-time applications like chatbots. Dynamic batching groups multiple inference requests into a single batch, leveraging GPU parallelism to process them simultaneously, thus reducing per-request latency. According to NVIDIA's Triton documentation, this is particularly effective for LLMs with variable input sizes, as it maximizes resource utilization. Option A is incorrect, as increasing parameters increases latency. Option C may reduce latency but sacrifices context and quality. Option D is false, as CPU-based inference is slower than GPU-based for LLMs.

NEW QUESTION # 29
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.

NEW QUESTION # 30
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
