NVIDIA-Certified Associate AI Infrastructure and Operations Sample Questions (Q111-Q116):

NEW QUESTION # 111
During routine monitoring of your AI data center, you notice that several GPU nodes are consistently reporting high memory usage but low compute usage. What is the most likely cause of this situation?

  • A. The power supply to the GPU nodes is insufficient
  • B. The GPU drivers are outdated and need updating
  • C. The data being processed includes large datasets that are stored in GPU memory but not efficiently utilized by the compute cores
  • D. The workloads are being run with models that are too small for the available GPUs

Answer: C

Explanation:
The most likely cause is thatthe data being processed includes large datasets that are stored in GPU memory but not efficiently utilized by the compute cores(D). This scenario occurs when a workload loads substantial data into GPU memory (e.g., large tensors or datasets) but the computation phase doesn't fully leverage the GPU's parallel processing capabilities, resulting in high memory usage and low compute utilization. Here's a detailed breakdown:
* How it happens: In AI workloads, especially deep learning, data is often preloaded into GPU memory (e.g., via CUDA allocations) to minimize transfer latency. If the model or algorithm doesn't scale its compute operations to match the data size-due to small batch sizes, inefficient kernel launches, or suboptimal parallelization-the GPU cores remain underutilized while memory stays occupied. For example, a small neural network processing a massive dataset might only use a fraction of the GPU's thousands of cores, leaving compute idle.
* Evidence: High memory usage indicates data residency, while low compute usage (e.g., via nvidia-smi) shows that the CUDA cores or Tensor Cores aren't being fully engaged. This mismatch is common in poorly optimized workloads.
* Fix: Optimize the workload by increasing batch size, using mixed precision to engage Tensor Cores, or redesigning the algorithm to parallelize compute tasks better, ensuring data in memory is actively processed.
Why not the other options?
* A (Insufficient power supply): This would cause system instability or shutdowns, not a specific memory-compute imbalance. Power issues typically manifest as crashes, not low utilization.
* B (Outdated drivers): Outdated drivers might cause compatibility or performance issues, but they wouldn't selectively increase memory usage while reducing compute-symptoms would be more systemic (e.g., crashes or errors).
* C (Models too small): Small models might underuse compute, but they typically require less memory, not more, contradicting the high memory usage observed.
NVIDIA's optimization guides highlight efficient data utilization as key to balancing memory and compute (D).


NEW QUESTION # 112
A financial services company is using an AI model for fraud detection, deployed on NVIDIA GPUs. After deployment, the company notices a significant delay in processing transactions, which impacts their operations. Upon investigation, it's discovered that the AI model is being heavily used during peak business hours, leading to resource contention on the GPUs. What is the best approach to address this issue?

  • A. Implement GPU load balancing across multiple instances
  • B. Disable GPU monitoring to free up resources
  • C. Switch to using CPU resources instead of GPUs for processing
  • D. Increase the batch size of input data for the AI model

Answer: A

Explanation:
Implementing GPU load balancing across multiple instances is the best approach to address resource contention and delays in a fraud detection system during peak hours. Load balancing distributes inference workloads across multiple NVIDIA GPUs (e.g., in a DGX cluster or Kubernetes setup with Triton Inference Server), ensuring no single GPU is overwhelmed. This maintains low latency and high throughput, as recommended in NVIDIA's "AI Infrastructure and Operations Fundamentals" and "Triton Inference Server Documentation" for production environments.
Switching to CPUs (A) sacrifices GPU performance advantages. Disabling monitoring (B) doesn't address contention and hinders diagnostics. Increasing batch size (C) may worsen delays by overloading GPUs. Load balancing is NVIDIA's standard solution for peak load management.


NEW QUESTION # 113
You are tasked with optimizing an AI-driven financial modeling application that performs both complex mathematical calculations and real-time data analytics. The calculations are CPU-intensive, requiring precise sequential processing, while the data analytics involves processing large datasets in parallel. How should you allocate the workloads across GPU and CPU architectures?

  • A. Use GPUs for mathematical calculations and CPUs for managing I/O operations
  • B. Use GPUs for both the mathematical calculations and data analytics
  • C. Use CPUs for mathematical calculations and GPUs for data analytics
  • D. Use CPUs for data analytics and GPUs for mathematical calculations

Answer: C

Explanation:
Allocating CPUs for mathematical calculations and GPUs for data analytics (C) optimizes performance based on architectural strengths. CPUs excel at sequential, precise tasks like complex financial calculations due to their high clock speeds and robust single-thread performance. GPUs, with thousands of parallel cores (e.g., NVIDIA A100), are ideal for data analytics, accelerating large-scale, parallel operations like matrix computations or aggregations in real-time. This hybrid approach leverages NVIDIA RAPIDS for GPU- accelerated analytics while reserving CPUs for sequential logic.
* CPUs for analytics, GPUs for calculations(A) reverses strengths, slowing analytics.
* GPUs for calculations, CPUs for I/O(B) misaligns compute needs; I/O isn't the primary workload.
* GPUs for both(D) underutilizes CPUs and may struggle with sequential precision.
NVIDIA's hybrid computing model supports this allocation (C).


NEW QUESTION # 114
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. Profile the I/O operations on the storage system
  • B. Switch to a different data preprocessing framework
  • C. Increase the number of GPUs used for data processing
  • D. Optimize the AI model's inference code

Answer: A

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 # 115
Which NVIDIA solution is specifically designed to accelerate the development and deployment of AI in healthcare, particularly in medical imaging and genomics?

  • A. NVIDIA TensorRT
  • B. NVIDIA Jetson
  • C. NVIDIA Metropolis
  • D. NVIDIA Clara

Answer: D

Explanation:
NVIDIA Clara is specifically designed to accelerate AI development and deployment in healthcare, focusing on medical imaging and genomics with tools like Clara Imaging and Clara Genomics. Option A (Jetson) targets edge AI. Option B (TensorRT) optimizes inference broadly. Option C (Metropolis) focuses on smart cities. NVIDIA's Clara documentation confirms its healthcare specialization.
