최신 NVIDIA-Certified Associate NCA-AIIO 무료샘플문제 (Q87-Q92):
질문 # 87
Your team is running an AI inference workload on a Kubernetes cluster with multiple NVIDIA GPUs. You observe that some nodes with GPUs are underutilized, while others are overloaded, leading to inconsistent inference performance across the cluster. Which strategy would most effectively balance the GPU workload across the Kubernetes cluster?
- A. Deploying a GPU-aware scheduler in Kubernetes
- B. Using CPU-based autoscaling to balance the workload
- C. Implementing GPU resource quotas to limit GPU usage per pod
- D. Reducing the number of GPU nodes in the cluster
정답：A
설명：
Deploying a GPU-aware scheduler in Kubernetes (A) is the most effective strategy to balance GPU workloads across a cluster. Kubernetes by default does not natively understand GPU resources beyond basic resource requests and limits. A GPU-aware scheduler, such as the NVIDIA GPU Operator with Kubernetes, enhances the orchestration by intelligently distributing workloads basedon GPU availability, utilization, and specific requirements of the inference tasks. This ensures that underutilized nodes are assigned work while preventing overloading of others, leading to consistent performance.
* Implementing GPU resource quotas(B) can limit GPU usage per pod, but it doesn't dynamically balance workloads across nodes-it only caps resource consumption, potentially leaving some GPUs idle if quotas are too restrictive.
* Using CPU-based autoscaling(C) focuses on CPU metrics and ignores GPU-specific utilization, making it ineffective for GPU workload balancing in this scenario.
* Reducing the number of GPU nodes(D) might exacerbate the issue by reducing overall capacity, not addressing the imbalance.
The NVIDIA GPU Operator integrates with Kubernetes to provide GPU-aware scheduling, monitoring, and management, making (A) the optimal solution.
질문 # 88
Which of the following NVIDIA compute platforms is best suited for deploying AI workloads at the edge with minimal latency?
- A. NVIDIA RTX
- B. NVIDIA GRID
- C. NVIDIA Tesla
- D. NVIDIA Jetson
정답：D
설명：
NVIDIA Jetson (D) is best suited for deploying AI workloads at the edge with minimal latency. The Jetson family (e.g., Jetson Nano, AGX Xavier) is designed for compact, power-efficient edge computing, delivering real-time AI inference for applications like IoT, robotics, and autonomous systems. It integrates GPU, CPU, and I/O in a single module, optimized for low-latency processing on-site.
* NVIDIA GRID(A) is for virtualized GPU sharing, not edge deployment.
* NVIDIA Tesla(B) is a data center GPU, too power-hungry for edge use.
* NVIDIA RTX(C) targets gaming/workstations, not edge-specific needs.
Jetson's edge focus is well-documented by NVIDIA (D).
질문 # 89
You are managing a data center running numerous AI workloads on NVIDIA GPUs. Recently, some of the GPUs have been showing signs of underperformance, leading to slower job completion times. You suspect that resource utilization is not optimal. You need to implement monitoring strategies to ensure GPUs are effectively utilized and to diagnose any underperformance. Which of the following metrics is most critical to monitor for identifying underutilized GPUs in your data center?
- A. Network Bandwidth Utilization
- B. System Uptime
- C. GPU Memory Usage
- D. GPU Core Utilization
정답：D
설명：
GPU Core Utilization is the most critical metric for identifying underutilized GPUs in an AI data center. This metric, accessible via NVIDIA's nvidia-smi or DCGM, measures the percentage of time GPU cores are actively processing tasks, directly indicating whether GPUs are underperforming due to idle time or poor workload distribution. Low core utilization suggests inefficient task scheduling or bottlenecks elsewhere (e.g., CPU, I/O). Option B (memory usage) is important but secondary, as high memory use doesn't guarantee core activity. Option C (network bandwidth) affects distributed workloads, not local GPU use. Option D (uptime) ensures availability, not utilization. NVIDIA's monitoring guidelines prioritize core utilization for performance diagnostics.
질문 # 90
Your organization has deployed a large-scale AI data center with multiple GPUs running complex deep learning workloads. You've noticed fluctuating performance and increasing energy consumption across several nodes. You need to optimize the data center's operation and improve energy efficiency while ensuring high performance. Which of the following actions should you prioritize to achieve optimized AI data center management and maintain efficient energyconsumption?
- A. Disable power management features on all GPUs to ensure maximum performance
- B. Install additional GPUs to distribute the workload more evenly
- C. Implement GPU workload scheduling based on real-time performance metrics
- D. Increase the number of active cooling systems to reduce thermal throttling
정답：C
설명：
Implementing GPU workload scheduling based on real-time performance metrics is the priority action to optimize AI data center management and improve energy efficiency while maintaining performance. Using tools like NVIDIA DCGM, this approach monitors metrics (e.g., power usage, utilization) and schedules workloads to balance load, reduce idle time, and leverage power-saving features (e.g., GPU Boost). This aligns with NVIDIA's "AI Infrastructure and Operations Fundamentals" for energy-efficient GPU management without sacrificing throughput.
Disabling power management (A) increases consumption unnecessarily. Adding GPUs (C) raises costs without addressing efficiency. More cooling (D) mitigates symptoms, not root causes. NVIDIA prioritizes dynamic scheduling for optimization.
질문 # 91
In an AI data center, ensuring the health and performance of GPU resources is critical. You notice that some workloads are unexpectedly failing or slowing down. Which monitoring approach would be most effective in proactively detecting and resolving these issues?
- A. Review system logs weekly.
- B. Set up NVIDIA DCGM health checks and alerts.
- C. Monitor server uptime and network latency.
- D. Deploy automatic workload restart mechanisms.
정답：B
설명：
NVIDIA's Data Center GPU Manager (DCGM) is specifically designed to monitor GPU health and performance in real-time, making it the most effective solution for proactively detecting and resolving issues like workload failures or slowdowns. DCGM provides detailed telemetry, including GPU utilization, memory usage, temperature, and error states, and supports health checks and alerts to notify administrators of anomalies (e.g., GPU faults, thermal throttling). Option A (weekly log reviews) is reactive and too slow for real-time issue detection in an AI data center. Option B (monitoring uptime and latency) provides indirect metrics but lacks GPU-specific insights critical for diagnosing failures. Option D (automatic restarts) addresses symptoms without identifying root causes, risking recurring issues. NVIDIA's official DCGM documentation emphasizes its role in cluster management, offering automated diagnostics and integration with tools like Prometheus for proactive monitoring, ensuring optimal GPU performance.
