NVIDIA-Certified Associate AI Infrastructure and Operations Sample Questions (Q39-Q44):

NEW QUESTION # 39
What is the primary command for checking the GPU utilization on a single DGX H100 system?

A. nvidia-smi
B. ctop
C. nvml

Answer: A

Explanation:
The nvidia-smi (System Management Interface) command is the primary tool for checking GPU utilization on NVIDIA systems, including the DGX H100. It provides real-time metrics like utilization percentage, memory usage, and power draw. NVML (NVIDIA Management Library) is an API, not a command, and ctop is unrelated, solidifying nvidia-smi as the standard.
(Reference: NVIDIA DGX H100 System Documentation, Monitoring Section)

NEW QUESTION # 40
You are part of a team working on optimizing an AI model that processes video data in real-time. The model is deployed on a system with multiple NVIDIA GPUs, and the inference speed is not meeting the required thresholds. You have been tasked with analyzing the data processing pipeline under the guidance of a senior engineer. Which action would most likely improve the inference speed of the model on the NVIDIA GPUs?

A. Profile the data loading process to ensure it's not a bottleneck.
B. Increase the batch size used during inference.
C. Enable CUDA Unified Memory for the model.
D. Disable GPU power-saving features.

Answer: A

Explanation:
Inference speed in real-time video processing depends not only on GPU computation but also on the efficiency of the entire pipeline, including data loading. If the data loading process (e.g., fetching and preprocessing video frames) is slow, it can starve the GPUs, reducing overall throughput regardless of their computational power. Profiling this process-using tools like NVIDIA Nsight Systems or NVIDIA Data Center GPU Manager (DCGM)-identifies bottlenecks, such as I/O delays or inefficient preprocessing, allowing targeted optimization. NVIDIA's Data Loading Library (DALI) can further accelerate this step by offloading data preparation to GPUs.
CUDA Unified Memory (Option A) simplifies memory management but may not directly address speed if the bottleneck isn't memory-related. Disabling power-saving features (Option B) might boost GPU performance slightly but won't fix pipeline inefficiencies. Increasing batch size (Option D) can improve throughput for some workloads but may increase latency, which is undesirable for real-time applications. Profiling is the most systematic approach, aligning with NVIDIA's performance optimization guidelines.

NEW QUESTION # 41
You are optimizing an AI data center that uses NVIDIA GPUs for energy efficiency. Which of the following practices would most effectively reduce energy consumption while maintaining performance?

A. Enabling NVIDIA's Adaptive Power Management features
B. Utilizing older GPUs to reduce power consumption
C. Running all GPUs at maximum clock speeds
D. Disabling power capping to allow full power usage

Answer: A

Explanation:
Enabling NVIDIA's Adaptive Power Management features (B) is the most effective practice to reduce energy consumption while maintaining performance. NVIDIA GPUs, such as the A100, support power management capabilities that dynamically adjust power usage based on workload demands. Features like Multi-Instance GPU (MIG) and power capping allow the GPU to scale clock speeds and voltage efficiently, minimizing energy waste during low-utilization periods without sacrificing performance for AI tasks. This is managed via tools like NVIDIA System Management Interface (nvidia-smi).
* Disabling power capping(A) allows GPUs to consume maximum power continuously, increasing energy use unnecessarily.
* Running GPUs at maximum clock speeds(C) boosts performance but significantly raises power consumption, countering efficiency goals.
* Utilizing older GPUs(D) may lower power draw but reduces performance and efficiency due to outdated architecture (e.g., less efficient FLOPS/watt).
NVIDIA's documentation emphasizes Adaptive Power Management for energy-efficient AI data centers (B).

NEW QUESTION # 42
Which networking feature is most important for supporting distributed training of large AI models across multiple data centers?

A. Implementation of Quality of Service (QoS) policies to prioritize AI training traffic
B. High throughput with low latency WAN links between data centers
C. Deployment of wireless networking to enable flexible node placement
D. Segregated network segments to prevent data leakage between AI tasks

Answer: B

Explanation:
High throughput with low latency WAN links between data centers is the most important networking feature for supporting distributed training of large AI models. Distributed training across multiple data centers requires rapid exchange of gradients and model parameters, which demands high-bandwidth, low-latency connections (e.g., InfiniBand or high-speed Ethernet over WAN). NVIDIA's "DGX SuperPOD Reference Architecture" and "AI Infrastructure for Enterprise" emphasize that network performance is critical for scaling AI training geographically, ensuring synchronization and minimizing training time.
QoS policies (B) prioritize traffic but don't address raw performance needs. Segregated segments (C) enhance security, not training efficiency. Wireless networking (D) lacks the reliability and bandwidth for data center AI. NVIDIA prioritizes high-throughput, low-latency networking for distributed training.

NEW QUESTION # 43
Which of the following best describes the primary benefit of using GPUs over CPUs for AI workloads?

A. GPUs consume less power than CPUs for AI tasks.
B. GPUs provide better accuracy in AI model predictions.
C. GPUs are designed to handle parallel processing tasks efficiently.
D. GPUs have higher memory capacity than CPUs.

Answer: C

Explanation:
The primary benefit of GPUs over CPUs for AI workloads is their design for efficient parallel processing, leveraging thousands of cores (e.g., in NVIDIA A100) to accelerate tasks like matrix operations in deep learning. Option A (accuracy) depends on models, not hardware. Option B (power) is false; GPUs consume more power. Option C (memory) varies but isn't primary. NVIDIA's GPU architecture documentation highlights parallel processing as the key advantage.
