質問 # 102
Your AI team is deploying a real-time video processing application that leverages deep learning models across a distributed system with multiple GPUs. However, the application faces frequent latency spikes and inconsistent frame processing times, especially when scaling across different nodes. Upon review, you find that the network bandwidth between nodes is becoming a bottleneck, leading to these performance issues.
Which strategy would most effectively reduce latency and stabilize frame processing times in this distributed AI application?
正解：B
解説：
Implementing data compression techniques for inter-node communication is the most effective strategy to reduce latency and stabilize frame processing times in a distributed real-time videoprocessing application.
When network bandwidth between nodes is a bottleneck, compressing the data (e.g., frames or intermediate model outputs) before transmission reduces the volume of data transferred, alleviating network congestion and improving latency. NVIDIA's documentation, such as the "DeepStream SDK Reference" and "AI Infrastructure for Enterprise," highlights the importance of optimizing inter-node communication for distributed GPU systems, including compression as a viable technique.
Increasing GPUs per node (A) may improve local processing but does not address inter-node bandwidth issues. Reducing video resolution (B) lowers data load but sacrifices quality, which may not be acceptable.
Optimizing models for lower complexity (C) reduces compute load but does not directly solve network bottlenecks. NVIDIA's guidance on distributed systems emphasizes communication optimization, making compression the best solution here.
質問 # 103
Which data format is best for efficient and accurate AI model training?
正解：B
解説：
Mixed precision (FP8/FP16/TF32/FP32) allows AI models to balance computational speed and numerical accuracy, optimizing memory usage and accelerating training without significant loss of model fidelity.
質問 # 104
When training a neural network, what is the most common pattern of storage access?
正解：A
解説：
Training neural networks typically involves streaming large datasets from storage in a sequential read pattern. This ordered access maximizes throughput and minimizes seek overhead, as training pipelines ingest data in batches for processing across epochs. Writes (e.g., model checkpoints) are less frequent and typically sequential, while random writes are rare, making sequential reads the dominant pattern. (Note: The document incorrectly lists C as the answer; B aligns with NVIDIA's documentation.)
質問 # 105
In your AI infrastructure, several GPUs have recently failed during intensive training sessions. To proactively prevent such failures, which GPU metric should you monitor most closely?
正解：A
解説：
GPU Temperature (A) should be monitored most closely to prevent failures during intensive training.
Overheating is a primary cause of GPU hardware failure, especially under sustained high workloads like deep learning. Excessive temperatures can degrade components or trigger thermal shutdowns. NVIDIA's System Management Interface (nvidia-smi) tracks temperature, with thresholds (e.g., 85-90°C for many GPUs) indicating risk. Proactive cooling adjustments or workload throttling can prevent damage.
* Power Consumption(B) is related but less direct-high power can increase heat, but temperature is the failure trigger.
* Frame Buffer Utilization(C) reflects memory use, not physical failure risk.
* GPU Driver Version(D) affects functionality, not hardware health.
NVIDIA recommends temperature monitoring for reliability (A).
質問 # 106
What is the name of NVIDIA's SDK that accelerates machine learning?
正解：A
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.
