NVIDIA-Certified Associate AI Infrastructure and Operations 認定 NCA-AIIO 試験問題 (Q39-Q44):

質問 # 39
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. Implement the AI system on NVIDIA Quadro RTX GPUs across local servers in each hospital
B. Deploy the AI model on NVIDIA DGX A100 systems in a centralized data center with NVIDIA Clara
C. Use NVIDIA Jetson Nano devices at each hospital for image processing
D. Deploy the system using generic CPU servers with TensorFlow for model training and inference

正解：B

解説：
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.

質問 # 40
You are working with a large healthcare dataset containing millions of patient records. Your goal is to identify patterns and extract actionable insights that could improve patient outcomes. The dataset is highly dimensional, with numerous variables, and requires significant processing power to analyze effectively.
Which two techniques are most suitable for extracting meaningful insights from this large, complex dataset?
(Select two)

A. Dimensionality Reduction (e.g., PCA)
B. K-means Clustering
C. SMOTE (Synthetic Minority Over-sampling Technique)
D. Data Augmentation
E. Batch Normalization

正解：A、B

解説：
A large, high-dimensional healthcare dataset requires techniques to uncover patterns and reduce complexity.
K-means Clustering (Option D) groups similar patient records (e.g., by symptoms or outcomes), identifying actionable patterns using NVIDIA RAPIDS cuML for GPU acceleration. Dimensionality Reduction (Option E), like PCA, reduces variables to key components, simplifying analysis while preserving insights, also accelerated by RAPIDS on NVIDIA GPUs (e.g., DGX systems).
SMOTE (Option A) addresses class imbalance, not general pattern extraction. Data Augmentation (Option B) enhances training data, not insight extraction. Batch Normalization (Option C) is a training technique, not an analysis tool. NVIDIA's data science tools prioritize clustering and dimensionality reduction for such tasks.

質問 # 41
What is the name of NVIDIA's SDK that accelerates machine learning?

A. RAPIDS
B. cuDNN
C. Clara

正解：B

解説：
The CUDA Deep Neural Network library (cuDNN) is NVIDIA's SDK specifically designed to accelerate machine learning, particularly deep learning tasks. It provides highly optimized implementations of neural network primitives-such as convolutions, pooling, normalization, and activation functions-leveraging GPU parallelism. Clara focuses on healthcare applications, and RAPIDS accelerates data science workflows, but cuDNN is the core SDK for machine learning acceleration.
(Reference: NVIDIA cuDNN Documentation, Introduction)

質問 # 42
What is a key benefit of using NVIDIA GPUDirect RDMA in an AI environment?

A. It allows multiple GPUs to share the same memory space without any synchronization.
B. It increases the power efficiency and thermal management of GPUs.
C. It reduces the latency and bandwidth overhead of remote memory access between GPUs.
D. It enables faster data transfers between GPUs and CPUs without involving the operating system.

正解：D

解説：
NVIDIA GPUDirect RDMA allows network adapters to directly access GPU memory, bypassing the CPU and operating system kernel. This accelerates data transfers between GPUs and CPUs (or other devices), reducing latency and CPU overhead in AI workflows, such as multi-node training. It doesn't focus on power efficiency or unsynchronized memory sharing, making faster transfers its key benefit.
(Reference: NVIDIA GPUDirect RDMA Documentation, Overview Section)

質問 # 43
You are comparing several regression models that predict the future sales of a product based on historical data. The models vary in complexity and computational requirements. Your goal is to select the model that provides the best balance between accuracy and the ability to generalize to new data. Which performance metric should you prioritize to select the most reliable regression model?

A. Mean Squared Error (MSE)
B. R-squared (Coefficient of Determination)
C. Accuracy
D. Cross-Entropy Loss

正解：B

解説：
R-squared (Coefficient of Determination) is the performance metric to prioritize when selecting a regression model that balances accuracy and generalization. R-squared measures the proportion of variance in the dependent variable (sales) explained by the independent variables, ranging from 0 to 1. A higher R-squared indicates better fit, but when paired with techniques like cross-validation, italso reflects the model's ability to generalize to new data, avoiding overfitting. This aligns with NVIDIA's AI development best practices, which emphasize robust model evaluation for real-world deployment.
Mean Squared Error (MSE) (A) quantifies prediction error but does not directly assess generalization.
Accuracy (B) is for classification, not regression. Cross-Entropy Loss (D) is for classification tasks, irrelevant here. NVIDIA's "Deep Learning Institute (DLI)" training and "AI Infrastructure and Operations" materials recommend R-squared for regression model selection.
