An infrastructure architect is selecting a network technology for a dedicated AI training cluster requiring extremely low latency, adaptive routing, congestion control, and efficient collective communications across thousands of GPUs. Which networking solution is generally the preferred choice for this environment?

• A.InfiniBand
• B.Wi-Fi 7
• C.Fibre Channel SAN
• D.Standard Layer 2 Ethernet without RDMA

What is the purpose of using NCCL in verifying east/west fabric in an NVIDIA AI Factory?
(Choose two.)

• A.To measure the storage network performance.
• B.To measure bandwidth between GPUs.
• C.To measure the latency between GPUs.
• D.To measure the power consumption of GPUs.

A network architect deploys a Spectrum Ethernet fabric for a RoCE-based AI cluster. During stress testing, distributed training performance fluctuates significantly because packet loss occurs whenever multiple training jobs execute simultaneously. Which network feature should be prioritized to improve communication consistency?

• A.Replacing all Top-of-Rack switches with PCIe switches
• B.Lossless Ethernet configuration with congestion management
• C.Increasing GPU memory allocation
• D.Disabling RDMA on every interface

Which software library provides GPU acceleration for pandas-like DataFrame operations?

• A.Intel oneAPI Data Analytics Library
• B.TensorFlow Data API
• C.RAPIDS cuDF
• D.R tidyverse

An AI infrastructure team upgrades a training cluster from PCIe-only GPU servers to HGX systems with NVLink and NVSwitch. Single-GPU benchmark results remain unchanged, but multi-GPU training jobs complete significantly faster. Which workload characteristic most directly benefits from the new architecture?

• A.Frequent peer-to-peer communication and collective operations among GPUs
• B.Local NVMe read performance for training datasets
• C.Kubernetes control plane scheduling latency
• D.Sequential CPU-intensive preprocessing before model execution
