NEW QUESTION # 65
An AI operations team is tasked with monitoring a large-scale AI infrastructure where multiple GPUs are utilized in parallel. To ensure optimal performance and early detection of issues, which two criteria are essential for monitoring the GPUs? (Select two)
Answer: B,C
Explanation:
For monitoring GPUs in an AI infrastructure:
* GPU utilization percentage(A) measures how effectively GPUs are being used, identifying underutilization or overloading-key to performance optimization.
* Memory bandwidth usage on GPUs(D) tracks data transfer rates within the GPU, critical for detecting bottlenecks in memory-intensive AI workloads like deep learning.
* Number of active CPU threads(B) is a CPU metric, less relevant to GPU performance.
* Average CPU temperature(C) monitors CPU health, not GPU status.
* GPU fan noise levels(E) are a byproduct, not a direct performance indicator.
NVIDIA's nvidia-smi tool provides these GPU metrics (A and D) for operational monitoring.
NEW QUESTION # 66
A logistics company wants to optimize its delivery routes by predicting traffic conditions and delivery times.
The system must process real-time data from various sources, such as GPS, weather reports, and traffic sensors, to adjust routes dynamically. Which approach should the company use to effectively handle this complex scenario?
Answer: C
Explanation:
A deep learning model with a CNN to process multi-source real-time data (GPS, weather, traffic) is best for dynamic route optimization. CNNs excel at spatial data analysis, enabling accurate predictions on NVIDIA GPUs. Option A (decision trees) lacks real-time adaptability. Option B (unsupervised) doesn't predict dynamically. Option C (rule-based) is static. NVIDIA's logistics use cases endorse deep learning for real-time optimization.
NEW QUESTION # 67
In an AI data center, you are working with a professional administrator to optimize the deployment of AI workloads across multiple servers. Which of the following actions would best contribute to improving the efficiency and performance of the data center?
Answer: C
Explanation:
Distributing AI workloads across multiple servers with GPUs, while using DPUs (e.g., NVIDIA BlueField) to manage network and storage tasks, best improves efficiency and performance in an AI data center. This approach leverages GPU parallelism for computation and offloads networking/storage (e.g., RDMA, encryption) to DPUs, reducing CPU overhead and latency. NVIDIA's "BlueField DPU Documentation" and
"AI Infrastructure for Enterprise" highlight this as an optimized design for scalable, high-performance AI deployments.
Consolidating workloads on one server (B) creates a bottleneck and single point of failure. Assigning networking to CPUs (C) negates DPU benefits, reducing efficiency. NVIDIA's architecture guidance supports distributed GPU-DPU setups.
NEW QUESTION # 68
Your AI team is running a distributed deep learning training job on an NVIDIA DGX A100 clusterusing multiple nodes. The training process is slowing down significantly as the model size increases. Which of the following strategies would be most effective in optimizing the training performance?
Answer: D
Explanation:
Enabling Mixed Precision Training is the most effective strategy to optimize training performance on an NVIDIA DGX A100 cluster as model size increases. Mixed precision uses lower-precision data types (e.g., FP16) alongside FP32, reducing memory usage and leveraging Tensor Cores on A100 GPUs for faster computation without significant accuracy loss. This approach, detailed in NVIDIA's "Mixed Precision Training Guide," accelerates training by allowing larger models to fit in GPU memory and speeding up matrix operations, addressing slowdowns in distributed setups.
Data parallelism (B) distributes data but may not help if memory constraints slow computation. Decreasing nodes (C) reduces parallelism, worsening performance. Increasing batch size (D) can strain memory further, exacerbating slowdowns. NVIDIA's DGX A100 documentation highlights mixed precision as a key optimization for large models.
NEW QUESTION # 69
What is the name of NVIDIA's SDK that accelerates machine learning?
Answer: B
Explanation:
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.
