NEW QUESTION # 81
What is a common tool used for container orchestration in AI clusters?
Answer: B
Explanation:
Kubernetes is widely used for container orchestration in AI clusters because it automates the deployment, scaling, and management of containerized workloads across distributed compute resources, which is essential for running and coordinating AI training and inference jobs at scale.
NEW QUESTION # 82
Which NVIDIA technology provides the broadest ecosystem for parallel computation across languages?
Answer: C
Explanation:
CUDA is the correct answer because it is NVIDIA's core parallel computing platform and programming model. NVIDIA's CUDA Programming Guide states: "CUDA is a parallel computing platform and programming model developed by NVIDIA that enables dramatic increases in computing performance by harnessing the power of the GPU." It also says CUDA is widely used in "deep learning, scientific computing, and high-performance computing (HPC)." NVIDIA's CUDA platform page further confirms the "across languages" part of the question: "Developers can program in languages such as C++, Python, and Fortran or leverage GPU-accelerated libraries and frameworks like PyTorch." Why the other options are incorrect: cuGraph is a GPU-accelerated graph analytics library, not the broad parallel-computing ecosystem. OpenCL is an open standard, but it is not NVIDIA's broadest software ecosystem. Triton Inference Server is for serving and managing AI inference workloads, not general-purpose parallel computation.
Reference: NVIDIA CUDA Programming Guide; NVIDIA CUDA Platform for Accelerated Computing.
NEW QUESTION # 83
You are working on a project that involves monitoring the performance of an AI model deployed in production. The model's accuracy and latency metrics are being tracked over time. Your task, under the guidance of a senior engineer, is to create visualizations that help the team understand trends in these metrics and identify any potential issues. Which visualization would be most effective for showing trends in both accuracy and latency metrics over time?
Answer: D
Explanation:
Tracking accuracy and latency trends over time requires a visualization that shows both metrics' evolution clearly. A dual-axis line chart, with accuracy on one axis and latency on the other, plots each as a line against time, revealing correlations (e.g., latency spikes reducing accuracy) and trends. NVIDIA RAPIDS supports such visualizations on GPUs, enhancing real-time monitoring in production environments like DGX or Triton deployments.
Pie charts (Option A) show distributions, not trends. Box plots (Option B) summarize static data, not time- based changes. Stacked area charts (Option C) imply cumulative values, confusing for independent metrics.
Dual-axis is NVIDIA-aligned for performance analysis.
NEW QUESTION # 84
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: A,E
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 # 85
Engineers are troubleshooting slow step-time and poor scaling efficiency in a multi-rack distributed AI training cluster. Which infrastructure change is MOST likely to improve end-to-end training performance?
Answer: D
Explanation:
End-to-end distributed training is often limited by collective communication, especially all-reduce across racks. NVIDIA's NCCL is optimized for high-bandwidth, low-latency interconnects such as InfiniBand and RoCE, and its documentation specifically notes optimization over InfiniBand and RoCE to maximize performance for collectives like all-reduce. A lossless RDMA-capable fabric therefore most directly improves step time and scaling efficiency in multi-node training.
