NVIDIA-Certified Associate AI Infrastructure and Operations Sample Questions (Q45-Q50):NEW QUESTION # 45
What is the maximum number of MIG instances that an H100 GPU provides?
Answer: B
Explanation:
The NVIDIA H100 GPU supports up to 7 Multi-Instance GPU (MIG) partitions, allowing it to be divided into seven isolated instances for multi-tenant or mixed workloads. This capability leverages the H100's architecture to maximize resource flexibility and efficiency, with 7 being the documented maximum.
(Reference: NVIDIA H100 GPU Documentation, MIG Section)

NEW QUESTION # 46
Your AI team is deploying a real-time video processing application that leverages deep learning models across a distributed system with multiple GPUs. However, the application faces frequent latency spikes and inconsistent frame processing times, especially when scaling across different nodes. Upon review, you find that the network bandwidth between nodes is becoming a bottleneck, leading to these performance issues.
Which strategy would most effectively reduce latency and stabilize frame processing times in this distributed AI application?
Answer: B
Explanation:
Implementing data compression techniques for inter-node communication is the most effective strategy to reduce latency and stabilize frame processing times in a distributed real-time videoprocessing application.
When network bandwidth between nodes is a bottleneck, compressing the data (e.g., frames or intermediate model outputs) before transmission reduces the volume of data transferred, alleviating network congestion and improving latency. NVIDIA's documentation, such as the "DeepStream SDK Reference" and "AI Infrastructure for Enterprise," highlights the importance of optimizing inter-node communication for distributed GPU systems, including compression as a viable technique.
Increasing GPUs per node (A) may improve local processing but does not address inter-node bandwidth issues. Reducing video resolution (B) lowers data load but sacrifices quality, which may not be acceptable.
Optimizing models for lower complexity (C) reduces compute load but does not directly solve network bottlenecks. NVIDIA's guidance on distributed systems emphasizes communication optimization, making compression the best solution here.

NEW QUESTION # 47
You have completed an analysis of resource utilization during the training of a deep learning model on an NVIDIA GPU cluster. The senior engineer requests that you create a visualization that clearly conveys the relationship between GPU memory usage and model training time across different training sessions. Which visualization would be most effective in conveying the relationship between GPU memory usage and model training time?
Answer: A
Explanation:
A scatter plot with GPU memory usage on one axis (e.g., x-axis) and training time on the other (e.g., y-axis) is the most effective visualization for conveying the relationship between these two variables across different training sessions. This type of plot allows you to plot individual data points for each session, revealing correlations, trends, or outliers (e.g., high memory usage leading to longer training times due to swapping).
NVIDIA's "AI Infrastructure and Operations Fundamentals" course and "NVIDIA DCGM" documentation encourage such visualizations for performance analysis, as they provide actionable insights into resource impacts on training efficiency.
A bar chart (A) shows averages but obscures session-specific relationships. A histogram (B) displays distribution, not pairwise relationships. A line chart (C) implies temporal continuity, which doesn't fit this use case. The scatter plot aligns with NVIDIA's best practices for GPU performance analysis.

NEW QUESTION # 48
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?
Answer: B
Explanation:
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.

NEW QUESTION # 49
Your organization runs multiple AI workloads on a shared NVIDIA GPU cluster. Some workloads are more critical than others. Recently, you've noticed that less critical workloads are consuming more GPU resources, affecting the performance of critical workloads. What is the best approach to ensure that critical workloads have priority access to GPU resources?
Answer: B
Explanation:
Ensuring critical workloads have priority in a shared GPU cluster requires resource control. Implementing GPU Quotas with Kubernetes Resource Management, using NVIDIA GPU Operator, assigns resource limits and priorities, ensuring critical tasks (e.g., via pod priority classes) access GPUs first. This aligns with NVIDIA's cluster management in DGX or cloud setups, balancing utilization effectively.
CPU-based inference (Option B) reduces GPU load but sacrifices performance for non-critical tasks.
Upgrading GPUs (Option C) increases capacity, not priority. Model optimization (Option D) improves efficiency but doesn't enforce priority. Quotas are NVIDIA's recommended strategy.
