NVIDIA-Certified Associate AI Infrastructure and Operations Sample Questions (Q13-Q18):

NEW QUESTION # 13
Your team is tasked with deploying a new AI-driven application that needs to perform real-time video processing and analytics on high-resolution video streams. The application must analyze multiple video feeds simultaneously to detect and classify objects with minimal latency. Considering the processing demands, which hardware architecture would be the most suitable for this scenario?

  • A. Deploy CPUs exclusively for all video processing tasks
  • B. Deploy GPUs to handle the video processing and analytics
  • C. Deploy a combination of CPUs and FPGAs for video processing
  • D. Use CPUs for video analytics and GPUs for managing network traffic

Answer: B

Explanation:
Real-time video processing and analytics on high-resolution streams require massive parallel computation, which NVIDIA GPUs excel at. GPUs handle tasks like object detection and classification (e.g., via CNNs) efficiently, minimizing latency for multiple feeds. NVIDIA's DeepStream SDK and TensorRT optimize this pipeline on GPUs, making them the ideal architecture for such workloads, as seen in DGX and Jetson deployments.
CPUs alone (Option A) lack the parallelism for real-time video analytics, causing delays. Using CPUs for analytics and GPUs for traffic (Option C) misaligns strengths-GPUs should handle compute-intensive analytics. CPUs with FPGAs (Option D) offer flexibility but lack the optimized software ecosystem (e.g., CUDA) that NVIDIA GPUs provide for AI. Option B is the most suitable, per NVIDIA's video analytics focus.


NEW QUESTION # 14
You are tasked with optimizing the performance of a deep learning model used for image recognition. The model needs to process a large dataset as quickly as possible while maintaining high accuracy. You have access to both GPU and CPU resources. Which two statements best describe why GPUs are more suitable than CPUs for this task? (Select two)

  • A. GPUs have a lower latency than CPUs, making them faster for individual calculations.
  • B. CPUs consume less power than GPUs, making them more suitable for prolonged computations.
  • C. GPUs have a higher number of cores compared to CPUs, allowing for parallel processing of many operations simultaneously.
  • D. GPUs are optimized for matrix operations, which are common in deep learning algorithms.
  • E. CPUs are better suited for handling the large dataset due to their superior memory bandwidth.

Answer: C,D

Explanation:
GPUs are more suitable than CPUs for image recognition due to:
* B: GPUs have a higher number of cores (e.g., thousands in NVIDIA A100), enabling parallel processing of operations like convolutions across large datasets, drastically reducing training time.


NEW QUESTION # 15
You are supporting a senior engineer in troubleshooting an AI workload that involves real-time data processing on an NVIDIA GPU cluster. The system experiences occasional slowdowns during data ingestion, affecting the overall performance of the AI model. Which approach would be most effective in diagnosing the cause of the data ingestion slowdown?

  • A. Increase the number of GPUs used for data processing
  • B. Profile the I/O operations on the storage system
  • C. Optimize the AI model's inference code
  • D. Switch to a different data preprocessing framework

Answer: B

Explanation:
Profiling the I/O operations on the storage system is the most effective approach to diagnose the cause of data ingestion slowdowns in a real-time AI workload on an NVIDIA GPU cluster. Slowdowns during ingestion often stem from bottlenecks in data transfer between storage and GPUs (e.g., disk I/O, network latency), which can starve the GPUs of data and degradeperformance. Tools like NVIDIA DCGM or system-level profilers (e.g., iostat, nvprof) can measure I/O throughput, latency, and bandwidth, pinpointing whether storage performance is the issue. NVIDIA's "AI Infrastructure and Operations" materials stress profiling I/O as a critical step in diagnosing data pipeline issues.
Switching frameworks (B) may not address the root cause if I/O is the bottleneck. Adding GPUs (C) increases compute capacity but doesn't solve ingestion delays. Optimizing inference code (D) improves model efficiency, not data ingestion. Profiling I/O is the recommended first step per NVIDIA guidelines.


NEW QUESTION # 16
You are working on a project that involves monitoring the performance of an AI model deployed in production. The model's accuracy and latency metrics are being tracked over time. Your task, under the guidance of a senior engineer, is to create visualizations that help the team understand trends in these metrics and identify any potential issues. Which visualization would be most effective for showing trends in both accuracy and latency metrics over time?

  • A. Box plot comparing accuracy and latency.
  • B. Stacked area chart showing cumulative accuracy and latency.
  • C. Pie chart showing the distribution of accuracy metrics.
  • D. Dual-axis line chart with accuracy on one axis and latency on the other.

Answer: D

Explanation:
Tracking accuracy and latency trends over time requires a visualization that shows both metrics' evolution clearly. A dual-axis line chart, with accuracy on one axis and latency on the other, plots each as a line against time, revealing correlations (e.g., latency spikes reducing accuracy) and trends. NVIDIA RAPIDS supports such visualizations on GPUs, enhancing real-time monitoring in production environments like DGX or Triton deployments.
Pie charts (Option A) show distributions, not trends. Box plots (Option B) summarize static data, not time- based changes. Stacked area charts (Option C) imply cumulative values, confusing for independent metrics.
Dual-axis is NVIDIA-aligned for performance analysis.


NEW QUESTION # 17
When virtualizing a GPU-accelerated infrastructure to support AI operations, what is a key factor to ensure efficient and scalable performance across virtual machines (VMs)?

  • A. Ensure that GPU memory is not overcommitted among VMs.
  • B. Allocate more network bandwidth to the host machine.
  • C. Increase the CPU allocation to each VM.
  • D. Enable nested virtualization on the VMs.

Answer: A

Explanation:
Ensuring that GPU memory is not overcommitted among VMs is a key factor for efficient and scalable performance in a virtualized GPU-accelerated infrastructure. NVIDIA's vGPU technology allows multiple VMs to share a GPU, but overcommitting memory (allocating more than physically available) causes contention, degrading performance. Proper memory allocation, as outlined in NVIDIA's vGPU documentation, ensures each VM has sufficient resources for AI workloads. Option A (more CPU) doesn't address GPU bottlenecks. Option C (network bandwidth) aids communication, not GPU efficiency. Option D (nested virtualization) adds complexity without direct benefit. NVIDIA emphasizes memory management for virtualization success.
