NVIDIA-Certified Associate AI Infrastructure and Operations Sample Questions (Q152-Q157):

NEW QUESTION # 152
A large healthcare provider wants to implement an AI-driven diagnostic system that can analyze medical images across multiple hospitals. The system needs to handle large volumes of data, comply with strict data privacy regulations, and provide fast, accurate results. The infrastructure should also support future scaling as more hospitals join the network. Which approach using NVIDIA technologies would best meet the requirements for this AI-driven diagnostic system?

  • A. Use NVIDIA Jetson Nano devices at each hospital for image processing
  • B. Implement the AI system on NVIDIA Quadro RTX GPUs across local servers in each hospital
  • C. Deploy the AI model on NVIDIA DGX A100 systems in a centralized data center with NVIDIA Clara
  • D. Deploy the system using generic CPU servers with TensorFlow for model training and inference

Answer: C

Explanation:
Deploying the AI model on NVIDIA DGX A100 systems in a centralized data center with NVIDIA Clara is the best approach for an AI-driven diagnostic system in healthcare. The DGX A100provides high- performance GPU computing for training and inference on large medical image datasets, while NVIDIA Clara offers a healthcare-specific AI platform with pre-trained models, privacy-preserving tools (e.g., federated learning), and scalability features. A centralized data center ensures compliance with privacy regulations (e.g., HIPAA) via secure data handling and supports future scaling as more hospitals join.
Generic CPU servers with TensorFlow (A) lack the GPU acceleration needed for fast, large-scale image analysis. Quadro RTX GPUs (B) are for visualization, not enterprise-scale AI diagnostics. Jetson Nano (C) is for edge inference, not centralized, scalable diagnostic systems. NVIDIA's "Clara Documentation" and "AI Infrastructure for Enterprise" validate this approach for healthcare AI.


NEW QUESTION # 153
When deploying AI workloads on a cloud platform using NVIDIA GPUs, which of the following is the most critical consideration to ensure cost efficiency without compromising performance?

  • A. Running all workloads on a single, high-performance GPU instance to minimize costs
  • B. Selecting the instance with the maximum GPU memory available
  • C. Using spot instances where applicable for non-critical workloads
  • D. Choosing a cloud provider that offers the lowest per-hour GPU cost

Answer: C

Explanation:
Using spot instances where applicable for non-critical workloads is the most critical consideration for cost efficiency without compromising performance. Spot instances, offered by cloud providerswith NVIDIA GPUs (e.g., DGX Cloud), provide significant cost savings for interruptible tasks like batch training, while reserved instances ensure performance for critical workloads. Option A (single instance) limits scalability.
Option C (lowest cost) risks performance trade-offs. Option D (max memory) increases costs unnecessarily.
NVIDIA's cloud deployment guides endorse spot instance strategies.


NEW QUESTION # 154
Your AI model training process suddenly slows down, and upon inspection, you notice that some of the GPUs in your multi-GPU setup are operating at full capacity while others are barely being used. What is the most likely cause of this imbalance?

  • A. Different GPU models are used in the same setup.
  • B. GPUs are not properly installed in the server chassis.
  • C. The AI model code is optimized only for specific GPUs.
  • D. Data loading process is not evenly distributed across GPUs.

Answer: D

Explanation:
Uneven GPU utilization in a multi-GPU setup often stems from an imbalanced data loading process. In distributed training, if data isn't evenly distributed across GPUs (e.g., via data parallelism), some GPUs receive more work while others idle, causing performance slowdowns. NVIDIA's NCCL ensures efficient communication between GPUs, but it relies on the data pipeline-managed by tools like NVIDIA DALI or PyTorch DataLoader-to distribute batches uniformly. A bottleneck in data loading, such as slow I/O or poor partitioning, is a common culprit, detectable via NVIDIA profiling tools like Nsight Systems.
Model code optimized for specific GPUs (Option A) is unlikely unless explicitly written to exclude certain GPUs, which is rare. Different GPU models (Option B) can cause imbalances due to varying capabilities, but NVIDIA frameworks typically handle heterogeneity; this would be a design flaw, not a sudden issue.
Improper installation (Option C) would likely cause complete failures, not partial utilization. Data distribution is the most probable and fixable cause, per NVIDIA's distributed training best practices.


NEW QUESTION # 155
When extracting insights from large datasets using data mining and data visualization techniques, which of the following practices is most critical to ensure accurate and actionable results?

  • A. Maximizing the size of the dataset used for training models.
  • B. Using complex algorithms with the highest computational cost.
  • C. Visualizing all possible data points in a single chart.
  • D. Ensuring the data is cleaned and pre-processed appropriately.

Answer: D

Explanation:
Accurate and actionable insights from data mining and visualization depend on high-quality data. Ensuring data is cleaned and pre-processed appropriately-removing noise, handling missing values, and normalizing features-prevents misleading results and ensures reliability. NVIDIA's RAPIDS library accelerates these steps on GPUs, enabling efficient preprocessing of large datasets for AI workflows, a critical practice in NVIDIA's data science ecosystem (e.g., DGX and NGC integrations).
Complex algorithms (Option A) may enhance analysis but are secondary to data quality; high cost doesn't guarantee accuracy. Visualizing all data points (Option C) can overwhelm charts, obscuring insights, and is less critical than preprocessing. Maximizing dataset size (Option D) can improve models but risks introducing noise if not cleaned, reducing actionability. NVIDIA's focus on data preparation in AI pipelines underscores Option B's importance.


NEW QUESTION # 156
A financial institution is implementing a real-time fraud detection system using deep learning models. The system needs to process large volumes of transactions with very low latency to identify fraudulent activities immediately. During testing, the team observes that the system occasionally misses fraudulent transactions under heavy load, and latency spikes occur. Which strategy would best improve the system's performance and reliability?

  • A. Deploy the model on a CPU cluster instead of GPUs to handle the processing.
  • B. Increase the dataset size by including more historical transaction data.
  • C. Implement model parallelism to split the model across multiple GPUs.
  • D. Reduce the complexity of the model to decrease the inference time.

Answer: C

Explanation:
Implementing model parallelism to split the deep learning model across multiple NVIDIA GPUs is the best strategy to improve performance and reliability for a real-time fraud detection system under heavy load.
Model parallelism divides the computational workload of a large model across GPUs, reducing latency and increasing throughput by leveraging parallel processing capabilities, a strength of NVIDIA's architecture (e.
g., TensorRT, NCCL). This addresses latency spikes and missed detections by ensuring the system scales with demand. Option A (CPU cluster) sacrifices GPU acceleration, increasing latency. Option B (reducing complexity) may lower accuracy, undermining fraud detection. Option C (larger dataset) improves training but not inference performance. NVIDIA's fraud detection use cases highlight model parallelism as a key optimization technique.
