ValidTorrent's web-based NVIDIA NCP-AIN practice test also contains mock exams just like the desktop practice exam software with some extra features. As this is a web-based software, this is accessible through any browser like Opera, Safari, Chrome, Firefox and MS Edge with a good internet connection. NVIDIA-Certified Professional AI Networking (NCP-AIN) practice test is also customizable so that you can easily set the timings and change the number of questions according to your ease.

NVIDIA-Certified Professional AI Networking Sample Questions (Q25-Q30):

NEW QUESTION # 25
How does Spectrum-X achieve network isolation for multiple tenants?

A. By implementing a Layer 3 Virtual Network Identifier (L3VNI) per VRR
B. By implementing physical network segmentation.
C. By assigning unique IP address ranges to each tenant.
D. Using manual configuration of access control lists (ACLs).

Answer: A

Explanation:
Spectrum-X achieves network isolation in multi-tenant environments by implementing Layer 3 Virtual Network Identifiers (L3VNIs) per Virtual Routing and Forwarding (VRF) instance. This approach allows each tenant to have a separate routing table and network segment, ensuring that traffic is isolated and secure between tenants.

NEW QUESTION # 26
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?

A. PCIe for intra-node GPU communication and RoCE for inter-node communication.
B. InfiniBand for both intra-node and inter-node GPU communication.
C. NVLink for both intra-node and inter-node GPU communication.
D. NVLink for intra-node GPU communication and InfiniBand for inter-node communication.

Answer: D

Explanation:
For optimal performance in multi-node, multi-GPU AI workloads:
* NVLinkprovides high-speed, low-latency communication between GPUs within the same node.
* InfiniBandoffers efficient, scalable communication between nodes in a data center.Combining these technologies ensures both intra-node and inter-node communication needs are effectively met.

NEW QUESTION # 27
You are troubleshooting a Spectrum-X network and need to ensure that the network remains operational in case of a link failure. Which feature of Spectrum-X ensures that the fabric continues to deliver high performance even if there is a link failure?

A. RoCE Adaptive Routing
B. RoCE Congestion Control
C. RoCE Performance Isolation
D. NVIDIA NetQ

Answer: A

Explanation:
RoCE Adaptive Routing is a key feature of NVIDIA Spectrum-X that ensures high performance and resiliency in the network, even in the event of a link failure. This technology dynamically reroutes traffic to the least congested and operational paths, effectively mitigating the impact of link failures. By continuously evaluating the network's egress queue loads and receiving status notifications from neighboring switches, Spectrum-X can adaptively select optimal paths for data transmission. This ensures that the network maintains high throughput and low latency, crucial for AI workloads, even when certain links are down.
Reference Extracts from NVIDIA Documentation:
* "Spectrum-X employs global adaptive routing to quickly reroute traffic during link failures, minimizing disruptions and preserving optimal storage fabric utilization."
* "RoCE Adaptive Routing avoids congestion by dynamically routing large AI flows away from congestion points. This approach improves network resource utilization, leaf/spine efficiency, and performance."

NEW QUESTION # 28
In which mode of the BlueField DPU does the ARM system on the DPU control the NIC data path, but allow access to the DPU OS from the host?

A. Restricted mode
B. DPU mode
C. Separated Host mode
D. NIC mode

Answer: B

NEW QUESTION # 29
Which service on Cumulus switches can monitor layer 1, layer 2, layer 3, tunnel, buffer, and ACL related issues?

A. WJH
B. ONIE
C. BGP
D. NCLU

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."
