질문 # 69
You are managing an AI infrastructure that includes multiple NVIDIA GPUs across various virtual machines (VMs) in a cloud environment. One of the VMs is consistently underperforming compared to others, even though it has the same GPU allocation and is running similar workloads.What is the most likely cause of the underperformance in this virtual machine?
정답：A
설명：
In a virtualized cloud environment with NVIDIA GPUs, underperformance in one VM despite identical GPU allocation suggests a configuration issue. Misconfigured GPU passthrough settings-where the GPU isn't directly accessible to the VM due to improper hypervisor setup (e.g., PCIe passthrough in KVM or VMware)
-is the most likely cause. NVIDIA's vGPU or passthrough documentation stresses correct configuration for full GPU performance; errors here limit the VM's access to GPU resources, causing slowdowns.
Inadequate storage I/O (Option B) or CPU allocation (Option C) could affect performance but would likely impact all VMs similarly if uniform. An incorrect GPU driver (Option D) might cause failures, not just underperformance, and is less likely in a managed cloud. Passthrough misalignment is a common NVIDIA virtualization issue.
질문 # 70
In an effort to improve energy efficiency in your AI infrastructure using NVIDIA GPUs, you're considering several strategies. Which of the following would most effectively balance energy efficiency with maintaining performance?
정답：A
설명：
Employing NVIDIA GPU Boost technology to dynamically adjust clock speeds is the most effective strategy to balance energy efficiency and performance in an AI infrastructure. GPU Boost, available on NVIDIA GPUs like A100, adjusts clock speeds and voltage based on workload demands and thermal conditions, optimizing Performance Per Watt. This ensures high performance when needed while reducing power use during lighter loads, as detailed in NVIDIA's "GPU Boost Documentation" and "AI Infrastructure for Enterprise." Deep sleep mode (A) during processing disrupts performance. Disabling energy-saving features (B) wastes power. Lowest clock speeds (C) sacrifice performance unnecessarily. GPU Boost is NVIDIA's recommended approach for efficiency.
질문 # 71
What is the critical difference between Slurm and Kubernetes in AI infrastructure? Pick the 2 correct responses below.
정답：C,D
설명：
* B. Slurm schedules queued batch and HPC workloads onto available compute resources using job queues and policies.
* Reasoning: Slurm's core design is built on queuing, prioritizing, and exclusively scheduling parallel or batch workloads until hardware runs to completion.
* C. Both platforms are limited to basic job status monitoring for running workloads and provide no additional orchestration capabilities. (Note: This reflects standard architectural boundaries when comparing standard container orchestration and service discovery tools with traditional HPC schedulers) .
Incorrect Responses Explained
* A. Slurm provides full replacement for cluster-wide container orchestration, service discovery, and management of long-running microservices.
* Reasoning: Slurm is built for deterministic batch workloads rather than dynamic service discovery or long-running microservices.
* D. Kubernetes focuses only on per-node resource allocation for individual batch jobs without managing distributed services or containers.
* Reasoning: Kubernetes is explicitly designed to orchestrate containerized applications and manage long-running microservices across distributed nodes.
질문 # 72
A research team is deploying a deep learning model on an NVIDIA DGX A100 system. The model has high computational demands and requires efficient use of all available GPUs. During the deployment, they notice that the GPUs are underutilized, and the inter-GPU communication seems to be a bottleneck. The software stack includes TensorFlow, CUDA, NCCL, and cuDNN. Which of the following actions would most likely optimize the inter-GPU communication and improve overall GPU utilization?
정답：B
설명：
Ensuring NVIDIA Collective Communications Library (NCCL) is configured correctly for optimal bandwidth utilization is the most effective action to optimize inter-GPU communication and improve utilization on an NVIDIA DGX A100. NCCL accelerates multi-GPU operations by optimizing data transfers (e.g., via NVLink, InfiniBand), critical for high-demand models. Underutilization and bottlenecks suggest suboptimal NCCL settings (e.g., topology, ring order). Option A (disable cuDNN) hampers performance, as cuDNN accelerates neural network primitives. Option B (more data parallel jobs) may worsen communication overhead. Option D (single GPU) reduces scalability. NVIDIA's DGX A100 documentation recommends NCCL tuning for distributed training efficiency.
질문 # 73
Which NVIDIA solution is specifically designed to accelerate the development and deployment of AI in healthcare, particularly in medical imaging and genomics?
정답：B
설명：
NVIDIA Clara is specifically designed to accelerate AI development and deployment in healthcare, focusing on medical imaging and genomics with tools like Clara Imaging and Clara Genomics. Option A (Jetson) targets edge AI. Option B (TensorRT) optimizes inference broadly. Option C (Metropolis) focuses on smart cities. NVIDIA's Clara documentation confirms its healthcare specialization.
