NVIDIA-Certified Associate AI Infrastructure and Operations NCA-AIIO Prüfungsfragen mit Lösungen (Q10-Q15):

10. Frage
The foundation of the NVIDIA software stack is the DGX OS. Which of the following Linux distributions is DGX OS built upon?

A. CentOS
B. Ubuntu
C. Red Hat

Antwort: B

Begründung:
DGX OS, the operating system powering NVIDIA DGX systems, is built on Ubuntu Linux, specifically the Long-Term Support (LTS) version. It integrates Ubuntu's robust base with NVIDIA-specific enhancements, including GPU drivers, tools, and optimizations tailored for AI and high-performance computing workloads.
Neither Red Hat nor CentOS serves as the foundation for DGX OS, making Ubuntu the correct choice.

11. Frage
Which of the following best describes how memory and storage requirements differ between training and inference in AI systems?

A. Inference usually requires more memory than training because of the need to load multiple models simultaneously.
B. Training and inference have identical memory and storage requirements since both involve processing data with the same models.
C. Training generally requires more memory and storage due to the need to process large datasets and store intermediate gradients.
D. Training can be done with minimal memory, focusing more on GPU performance, while inference requires extensive storage.

Antwort: C

Begründung:
Training and inference have distinct resource demands in AI systems. Training involves processing large datasets, computing gradients, and updating model weights, requiring significant memory (e.g., GPU VRAM) for intermediate tensors and storage for datasets and checkpoints. NVIDIA GPUs like the A100 with HBM3 memory are designed to handle these demands, often paired with high-capacity NVMe storage in DGX systems. Inference, conversely, uses a pre-trained model to make predictions, requiring less memory (only the model and input data) and minimal storage, focusing on low latency and throughput.
Option A is incorrect-training's iterative nature demands more resources than inference's single-pass execution. Option C is false; inference rarely loads multiple models at once unless explicitly designed that way, and its memory needs are lower. Option D reverses the reality-training needs substantial memory, not minimal, while inference prioritizes speed over storage. NVIDIA's documentation on training (e.g., DGX) versus inference (e.g., TensorRT) workloads confirms Option B.

12. Frage
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

Antwort: C

Begründung:
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.

13. Frage
What is one key advantage that Cloud GPU Infrastructure has over On-Prem GPU infrastructure?

A. Greater flexibility for hardware orchestration.
B. Lower cost barrier to entry.
C. Reduced cost of I/O traffic.

Antwort: B

Begründung:
Cloud GPU infrastructure lowers the cost barrier to entry by offering a pay-as-you-go model, eliminating the need for significant upfront capital expenditure on hardware. While on-prem may offer I/O cost savings or hardware control, the cloud's accessibility and reduced initial investment make it a compelling choice for organizations seeking immediate GPU access without large sunk costs.
(Reference: NVIDIA AI Infrastructure and Operations Study Guide, Section on Cloud GPU Advantages)

14. Frage
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?

A. Ensure NCCL is configured correctly for optimal bandwidth utilization.
B. Disable cuDNN to streamline GPU operations.
C. Switch to using a single GPU to reduce complexity.
D. Increase the number of data parallel jobs running simultaneously.

Antwort: A

Begründung:
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.
