Question 1

Your team is tasked with deploying a new AI-driven application that needs to perform real-time video processing and analytics on high-resolution video streams. The application must analyze multiple video feeds simultaneously to detect and classify objects with minimal latency. Considering the processing demands, which hardware architecture would be the most suitable for this scenario?

ADeploy CPUs exclusively for all video processing tasks

BDeploy GPUs to handle the video processing and analytics

CUse CPUs for video analytics and GPUs for managing network traffic

DDeploy a combination of CPUs and FPGAs for video processing

Answer : B

Real-time video processing and analytics on high-resolution streams require massive parallel computation, which NVIDIA GPUs excel at. GPUs handle tasks like object detection and classification (e.g., via CNNs) efficiently, minimizing latency for multiple feeds. NVIDIA's DeepStream SDK and TensorRT optimize this pipeline on GPUs, making them the ideal architecture for such workloads, as seen in DGX and Jetson deployments.

CPUs alone (Option A) lack the parallelism for real-time video analytics, causing delays. Using CPUs for analytics and GPUs for traffic (Option C) misaligns strengths---GPUs should handle compute-intensive analytics. CPUs with FPGAs (Option D) offer flexibility but lack the optimized software ecosystem (e.g., CUDA) that NVIDIA GPUs provide for AI. Option B is the most suitable, per NVIDIA's video analytics focus.

Question 2

You are managing a high-performance AI cluster where multiple deep learning jobs are scheduled to run concurrently. To maximize resource efficiency, which of the following strategies should youuse to allocate GPU resources across the cluster?

AUse a priority queue to assign GPUs to jobs based on their deadline, ensuring the most time-sensitive jobs complete first.

BAllocate all GPUs to the largest job to ensure its rapid completion, then proceed with smaller jobs.

CAllocate GPUs to jobs based on their compute intensity, reserving the most powerful GPUs for the most demanding tasks.

DAssign jobs to GPUs based on their geographic proximity to reduce data transfer times.

Answer : C

Maximizing resource efficiency in a high-performance AI cluster requires matching GPU capabilities to job requirements. Allocating GPUs based on compute intensity ensures that resource-intensive tasks (e.g., large models or datasets) run on high-performance GPUs (e.g., NVIDIA A100 or H100), while lighter tasks use less powerful ones (e.g., V100). NVIDIA's Multi-Instance GPU (MIG) and GPU Operator in Kubernetes support this strategy by allowing dynamic partitioning and allocation, optimizing utilization and throughput across the cluster.

A priority queue (Option A) focuses on deadlines but may underutilize GPUs if low-priority jobs are resource-heavy. Allocating all GPUs to one job (Option B) wastes resources when smaller jobs could run concurrently. Geographic proximity (Option D) reduces latency in distributed setups but doesn't address compute efficiency within a cluster. NVIDIA's emphasis on workload-aware scheduling in DGX and cloud environments supports Option C as the best approach.

Question 3

Your AI team is deploying a multi-stage pipeline in a Kubernetes-managed GPU cluster, where some jobs are dependent on the completion of others. What is the most efficient way to ensure that these job dependencies are respected during scheduling and execution?

AIncrease the Priority of Dependent Jobs

BUse Kubernetes Jobs with Directed Acyclic Graph (DAG) Scheduling

CDeploy All Jobs Concurrently and Use Pod Anti-Affinity

DManually Monitor and Trigger Dependent Jobs

Answer : B

Using Kubernetes Jobs with Directed Acyclic Graph (DAG) scheduling is the most efficient way to ensure job dependencies are respected in a multi-stage pipeline on a GPU cluster. Kubernetes Jobs allow you to define tasks that run to completion, and integrating a DAG workflow (e.g., via tools like Argo Workflows or Kubeflow Pipelines) enables you to specify dependencies explicitly. This ensures that dependent jobs only start after their prerequisites finish, automating the process and optimizing resource use on NVIDIA GPUs.

Increasing job priority (A) affects scheduling order but does not enforce dependencies. Deploying all jobs concurrently with pod anti-affinity (C) prevents resource contention but ignores execution order. Manual monitoring (D) is inefficient and error-prone. NVIDIA's 'DeepOps' and 'AI Infrastructure and Operations Fundamentals' recommend DAG-based scheduling for dependency management in Kubernetes GPU clusters.

Question 4

Which component of the NVIDIA AI software stack is primarily responsible for optimizing deep learning inference performance by leveraging the specific architecture of NVIDIA GPUs?

ANVIDIA cuDNN

BNVIDIA TensorRT

CNVIDIA Triton Inference Server

DNVIDIA CUDA Toolkit

Answer : B

NVIDIA TensorRT is the component primarily responsible for optimizing deep learning inference performance by leveraging NVIDIA GPU architecture (e.g., Tensor Cores on A100 GPUs). TensorRT optimizes trained models through techniques like layer fusion, precision reduction (e.g., FP16, INT8), and kernel tuning, delivering low-latency, high-throughput inference. It's tailored for production environments, as detailed in NVIDIA's 'TensorRT Developer Guide,' making it distinct from other stack components.

cuDNN (A) provides neural network primitives for training and inference but lacks TensorRT's optimization depth. Triton Inference Server (C) deploys models efficiently but relies on TensorRT for optimization. CUDA Toolkit (D) is a foundational platform, not specific to inference optimization. TensorRT is NVIDIA's core inference optimizer.

Question 5

Which industry has seen the most significant impact from AI-driven advancements, particularly in optimizing supply chain management and improving customer experience?

AHealthcare

BEducation

CRetail

DReal Estate

Answer : C

Retail has experienced the most significant impact from AI-driven advancements, particularly in optimizing supply chain management and enhancing customer experience. NVIDIA's AI solutions, such as those deployed with NVIDIA DGX systems and Triton Inference Server, enable retailers to leverage deep learning for real-time inventory management, demand forecasting, and personalized recommendations. According to NVIDIA's 'State of AI in Retail and CPG' survey report, AI adoption in retail has led to use cases like supply chain optimization (e.g., reducing stockouts) and customer experience improvements (e.g., AI-powered recommendation systems). These advancements are powered by GPU-accelerated analytics and inference, which process vast datasetsefficiently.

Healthcare (A) benefits from AI in diagnostics and drug discovery (e.g., NVIDIA Clara), but its primary focus is not supply chain or customer experience. Education (B) uses AI for personalized learning, but its scale and impact are less pronounced in these areas. Real Estate (D) leverages AI for property valuation and market analysis, but it lacks the extensive supply chain and customer-facing applications seen in retail. NVIDIA's official documentation, including 'AI Solutions for Enterprises' and retail-specific use cases, highlights retail as a leader in AI-driven transformation for these specific domains.

Question 6

A financial institution is implementing an AI-driven fraud detection system that needs to process millions of transactions daily in real-time. The system must rapidly identify suspicious activity and trigger alerts, while also continuously learning from new data to improve accuracy. Which architecture is most appropriate for this scenario?

ASingle GPU server with local SSD storage for both training and inference

BEdge-only deployment with ARM processors for both training and inference

CHybrid setup with multi-GPU servers for training and edge devices for inference

DCPU-based servers with cloud storage for centralized processing

Answer : C

A hybrid setup with multi-GPU servers (e.g., NVIDIA DGX) for training and edge devices (e.g., NVIDIA Jetson) for inference is most appropriate. Multi-GPU servers handle continuous training on large datasets with high compute power, while edge devices enable low-latency inference for real-time fraud detection, balancing scalability and speed. Option A (single GPU) lacks scalability. Option B (edge-only ARM) can't handle training demands. Option D (CPU-based) sacrifices GPU acceleration. NVIDIA's fraud detection architectures endorse this hybrid model.

Question 7

You are working on a project that involves both real-time AI inference and data preprocessing tasks. The AI models require high throughput and low latency, while the data preprocessing involves complex logic and diverse data types. Given the need to balance these tasks, which computing architecture should you prioritize for each task?

AUse GPUs for both AI inference and data preprocessing

BUse CPUs for both AI inference and data preprocessing

CPrioritize GPUs for AI inference and CPUs for data preprocessing

DDeploy AI inference on CPUs and data preprocessing on FPGAs

Answer : C

Prioritizing GPUs for AI inference and CPUs for data preprocessing is the best architecture to balance these tasks. GPUs excel at parallel computation, making them ideal for high-throughput, low-latency inference using NVIDIA tools like TensorRT or Triton. CPUs, with fewer but more powerful cores, handle complex, sequential preprocessing tasks (e.g., data cleaning, branching logic) efficiently, as noted in NVIDIA's 'AI Infrastructure for Enterprise' and 'GPU Architecture Overview.' This hybrid approach leverages each processor's strengths, optimizing overall performance.

Using GPUs for both (A) underutilizes CPUs for preprocessing. CPUs for both (B) sacrifices inference performance. CPUs for inference and FPGAs for preprocessing (D) misaligns with NVIDIA GPU strengths and adds complexity. NVIDIA recommends this CPU-GPU division.
