NVIDIA NCP-AIN - NVIDIA-Certified Professional AI Networking Certification Exam

Question #6 (Topic: Demo Questions)

Which service on Cumulus switches can monitor layer 1, layer 2, layer 3, tunnel, buffer, and ACL related issues?

WJH

ONIE

NCLU

BGP

Correct Answer: A

Explanation:

The "What Just Happened" (WJH) service on Cumulus switches provides real-time visibility into network problems by monitoring various layers and components, including layer 1, layer 2, layer 3, tunnel, buffer, and Access Control List (ACL) related issues. WJH streams detailed and contextual telemetry data, enabling administrators to diagnose and troubleshoot network problems effectively.
Reference Extracts from NVIDIA Documentation:
"WJH can monitor layer 1, layer 2, layer 3, tunnel, buffer and ACL related issues."
"The WJH service enables you to diagnose network problems by looking at dropped packets."

Question #7 (Topic: Demo Questions)

You are optimizing an AI workload that involves multiple GPUs across different nodes in a data center. The application requires both high-bandwidth GPU-to-GPU communication within nodes and efficient communication between nodes.
Which combination of NVIDIA technologies would best support this multi-node, multi-GPU AI workload?

NVLink for both intra-node and inter-node GPU communication.

InfiniBand for both intra-node and inter-node GPU communication.

NVLink for intra-node GPU communication and InfiniBand for inter-node communication.

PCIe for intra-node GPU communication and RoCE for inter-node communication.

Correct Answer: C

Explanation:

For optimal performance in multi-node, multi-GPU AI workloads:

NVLink provides high-speed, low-latency communication between GPUs within the same node.
InfiniBand offers efficient, scalable communication between nodes in a data center. Combining these technologies ensures both intra-node and inter-node communication needs are effectively met.
