NEW QUESTION # 110
Your company is developing an AI application that requires seamless integration of data processing, model training, and deployment in a cloud-based environment. The application must support real-time inference and monitoring of model performance. Which combination of NVIDIA software components is best suited for this end-to-end AI development and deployment process?
Answer: B
Explanation:
The combination ofNVIDIA RAPIDS + NVIDIA Triton Inference Server + NVIDIA DeepOps(D) is the most comprehensive solution for an end-to-end AI workflow in a cloud-based environment requiring data processing, training, deployment, real-time inference, and monitoring. Let's break this down step-by-step:
* NVIDIA RAPIDS: This is an open-source suite of GPU-accelerated libraries (e.g., cuDF, cuML) designed to speed up data processing and machine learning workflows. It handles the initial data preparation and preprocessing stages by replacing CPU-based tools like pandas with GPU-accelerated equivalents, ensuring that large datasets are processed efficiently in the cloud. For an AI application, RAPIDS ensures that data pipelines feeding into training are optimized for GPU performance, reducing bottlenecks.
* NVIDIA Triton Inference Server: This server is purpose-built for deploying AI models in production, supporting multiple frameworks (e.g., TensorFlow, PyTorch, ONNX) and optimizing real-time inference. It provides features like dynamic batching, model versioning, and integrated monitoring (via metrics endpoints), which are critical for the application's requirements of real-time inference and performance tracking. Triton leverages NVIDIA GPUs to deliver low-latency, high-throughput inference, making it ideal for cloud deployment.
* NVIDIA DeepOps: This is a set of tools and scripts for provisioning, managing, and monitoring GPU clusters, particularly in cloud or on-premises environments. DeepOps simplifies the deployment of Kubernetes-based GPU clusters, ensuring that the infrastructure supporting RAPIDS and Triton is scalable, reliable, and monitored. It integrates with orchestration tools to automate resource allocation, making it a key component for seamless end-to-end management.
Why not the other options?
* A (DeepOps + RAPIDS): Covers infrastructure and data processing but lacks a dedicated inference solution for real-time deployment and monitoring.
* B (Clara Deploy SDK + Triton): Clara Deploy is healthcare-specific, not general-purpose, limiting its relevance here despite Triton's strength.
* C (RAPIDS + TensorRT): TensorRT optimizes inference but lacks the deployment management and monitoring capabilities of Triton, and it doesn't cover infrastructure orchestration.
Option D provides a full-stack solution, aligning with NVIDIA's cloud AI ecosystem for data processing (RAPIDS), inference (Triton), and infrastructure (DeepOps).
NEW QUESTION # 111
How many Mellanox ConnectX-6 Single Port VPI cards are in a DGX A100 system?
Answer: B
Explanation:
The DGX A100 system includes eight Mellanox ConnectX-6 Single Port VPI cards, providing high-speed connectivity (up to 200 Gb/s) for clustering and data transfer. These cards support versatile protocols (InfiniBand or Ethernet), enabling robust multi-node AI workloads, with eight being the standard configuration for this system.

NEW QUESTION # 112
You are working on a high-performance AI workload that requires the deployment of deep learning models on a multi-GPU cluster. The workload needs to scale across multiple nodes efficiently while maintaining high throughput and low latency. However, during the deployment, you notice that the GPU utilization is uneven across the nodes, leading to performance bottlenecks. Which of the following strategies would be the most effective in addressing the uneven GPU utilization in this multi-node AI deployment?
Answer: D
Explanation:
Uneven GPU utilization across nodes in a multi-GPU cluster often results from poor task-to-GPU mapping, where some nodes are overloaded while others are underutilized. Enabling GPU affinity in the job scheduler (e.g., Slurm, Kubernetes with NVIDIA GPU Operator) ensures that tasks are pinned to specific GPUs, optimizing resource allocation and balancing utilization. This approach leverages NVIDIA's infrastructure tools to enforce locality, reducing communication overhead (via NVLink or InfiniBand) and ensuring each GPU is assigned an appropriate workload share, improving throughput and latency.
A CPU-based load balancer (Option A) is less effective for GPU-specific tasks, as it lacks awareness of GPU states. Increasing batch size (Option C) might improve throughput for individual GPUs but doesn't address inter-node imbalances and could increase latency. Mixed precision training (Option D) enhances performance per GPU but doesn't solve distribution issues. GPU affinity, supported by NVIDIA's scheduling frameworks, directly tackles the root cause.
NEW QUESTION # 113
Which situation MOST strongly indicates data leakage?
Answer: A
Explanation:
Using test-set information during training contaminates evaluation and leads to overly optimistic results.
NEW QUESTION # 114
What is a common tool for container orchestration in AI clusters?
Answer: A
Explanation:
Kubernetes is the industry-standard tool for container orchestration in AI clusters, automating deployment, scaling, and management of containerized workloads. Slurm manages job scheduling, Apptainer (formerly Singularity) runs containers, and MLOps is a practice, not a tool, making Kubernetes the clear leader in this domain.
