NVIDIA Generative AI Multimodal Sample Questions (Q19-Q24):

NEW QUESTION # 19
Consider a scenario where you are evaluating the performance of a multimodal A1 model that generates descriptions for images. However, the generated descriptions tend to be repetitive and lack diversity. Which of the following techniques can be employed to address this issue and encourage more diverse and creative outputs from the model? (Select TWO)

A. Employing a nucleus sampling (top-p sampling) decoding strategy.
B. Using a greedy decoding strategy.
C. Using a beam search decoding strategy with a small beam width.
D. Utilizing a temperature scaling parameter during decoding and increasing its value.
E. Increasing the model's training data size.

Answer: A,D

Explanation:
Nucleus sampling (top-p sampling) randomly samples from the smallest set of words whose cumulative probability mass exceeds a threshold p, encouraging more diverse outputs. Increasing the temperature scaling parameter makes the probability distribution flatter, leading to more exploration and less predictable (more creative) outputs. Beam search with a small beam width might still result in repetitive outputs. Increasing the training data size can help, but it might not directly address the lack of diversity. Greedy decoding always selects the most probable word, leading to repetitive and predictable outputs.

NEW QUESTION # 20
You are developing a system that uses a generative A1 model deployed with Triton Inference Server to create personalized avatars. You want to ensure that the system is robust against malicious inputs designed to generate offensive or harmful content. Which of the following security measures are most critical to implement in conjunction with Triton?

A. Implementing input validation to enforce a maximum length for text prompts, using a content moderation API to filter the output generated by the model, and logging all user activity for auditing purposes.
B. Using a web application firewall (WAF) to protect the Triton server from denial-of-service attacks, implementing role-based access control (RBAC) to limit user privileges, and regularly updating the Triton software to patch security vulnerabilities.
C. Encrypting all communication between the client and the Triton server using HTTPS, restricting access to the Triton server to a private network, and using strong passwords for all Triton accounts.
D. All of the above.
E. Rate limiting the number of requests per user, implementing input validation and sanitization to filter out potentially harmful prompts, and regularly auditing the generated content for offensive material.

Answer: D

Explanation:
All the security measures listed are crucial for protecting a generative A1 system from malicious inputs. (A, B, C, D). These steps ensure the system's security, protect sensitive data, prevent misuse, and allow you to monitor and respond to potential issues effectively.

NEW QUESTION # 21
Consider this PyTorch code snippet related to processing multimodal dat a. What is the primary purpose of the following code in the context of Generative A1?

A. To ensure images and text are processed in the same order during training.
B. To concatenate image and text data into a single tensor.
C. To resize all images to the same dimension.
D. To create a custom dataset class for handling paired image and text data.
E. To create separate data loaders for images and text.

Answer: D

Explanation:
The code defines a custom dataset class ( 'ImageTextDataset' ) which is the standard way in PyTorch to handle datasets that involve paired data, such as images and corresponding text descriptions. This allows for efficient loading and processing of the data during training. The snippet does not directly concatenate, ensure order, or specifically resize the images, though these could be parts of the larger system built upon the dataset class. It also doesn't create separate data loaders, but allows to create one dataset class and loader for the multimodal data.

NEW QUESTION # 22
You are tasked with building a multimodal A1 system that can generate video descriptions from video footage. You have experimented with several architectures, including combining CNNs for visual feature extraction and LSTMs for sequence generation. However, you are facing challenges with the model capturing long-range dependencies in the video. Which of the following architectural modifications or training techniques is MOST likely to address this issue?

A. Increasing the number of layers in the CNN to extract more detailed visual features.
B. Incorporating a Transformer-based architecture, such as a Vision Transformer (ViT) for visual feature extraction and a standard Transformer for sequence generation.
C. Reducing the frame rate of the input video to reduce the temporal complexity.
D. Using a smaller batch size during training to reduce memory consumption.

Answer: C

Explanation:
Transformers are known for their ability to capture long-range dependencies due to their self-attention mechanism. Replacing LSTMs with Transformers allows the model to attend to relevant parts of the video sequence regardless of their temporal distance. While CNNs can extract visual features, they don't inherently address long-range dependencies. RNNs are prone to vanishing gradients, making it difficult to learn long- range dependencies. Reducing the frame rate or batch size doesn't directly address the issue of capturing long-range dependencies within the video sequence.

NEW QUESTION # 23
You are building a multimodal application that needs to understand both image and text dat a. You want to use a pre-trained model but fine-tune it for your specific task. Which of the following strategies is MOST effective for fine-tuning a large pre-trained multimodal model?

A. Fine-tune only the text encoder layers, keeping the image encoder layers frozen.
B. Train a new classification head from scratch on top of the frozen pre-trained model.
C. Fine-tune the attention mechanism between the text and image encoders, while keeping the encoder weights frozen.
D. Fine-tune only the image encoder layers, keeping the text encoder layers frozen.
E. Fine-tune the entire model, including both text and image encoder layers, using a small learning rate.

Answer: E

Explanation:
Fine-tuning the entire model with a small learning rate allows the model to adapt to the specific nuances of the new task while leveraging the knowledge already learned during pre-training. Freezing layers can limit adaptability. Training only a new head might not fully utilize the pre-trained features.
