NVIDIA-Certified Professional AI Networking Sample Questions (Q63-Q68):

NEW QUESTION # 63
Which of the following statements are true about AI workloads and adaptive routing?
Pick the 2 correct responses below.

  • A. ECMP-based load balancing works best for AI workloads.
  • B. AI workloads are made of a small number of volumetric flows called elephant flows.
  • C. AI workloads have very high entropy that helps spread traffic evenly without congestion.
  • D. Flow-based load balancing mechanisms increase congestion risk.

Answer: B,D

Explanation:
AI workloads, particularly in large-scale training scenarios, are characterized by a small number of high- bandwidth, long-lived flows known as "elephant flows." These flows can dominate network traffic and are prone to causing congestion if not managed effectively.
Traditional flow-based load balancing mechanisms, such as Equal-Cost Multipath (ECMP), distribute traffic based on flow hashes. However, in AI workloads with lowentropy (i.e., limited variability in flow characteristics), ECMP can lead to uneven traffic distribution and congestion on certain paths.
Adaptive routing techniques, which dynamically adjust paths based on real-time network conditions, are more effective in managing AI traffic patterns and mitigating congestion risks.

NEW QUESTION # 64
Which of the following scenarios would the Network Traffic Map in UFM be least useful for troubleshooting?

  • A. When optimizing job placement and workload distribution across the cluster.
  • B. When troubleshooting a single node's hardware failure.
  • C. After making changes to network configuration.
  • D. When investigating reports of network congestion or latency problems.

Answer: B

Explanation:
The Network Traffic Map in NVIDIA's Unified Fabric Manager (UFM) provides a visual representation of the network topology and traffic flows, which is particularly useful for identifying congestion points, verifying network configurations, and optimizing workload distribution.
However, when troubleshooting a single node's hardware failure, the Network Traffic Map is less effective, as it focuses on network-level issues rather than individual hardware components.


NEW QUESTION # 65
How is congestion evaluated in an NVIDIA Spectrum-X system?

  • A. By measuring the number of connected devices in the network.
  • B. By assessing the physical distance between network devices.
  • C. By monitoring the CPU and power usage of network devices.
  • D. By analyzing the egress queue loads ensuring all ports are well-balanced.

Answer: D

Explanation:
In NVIDIA Spectrum-X, congestion is evaluated based on egress queue loads. Spectrum-4 switches assess the load on each egress queue and select the port with the minimal load for packet transmission. This approach ensures that all ports are well-balanced, optimizing network performance and minimizing congestion.


NEW QUESTION # 66
A financial services company is planning to implement an AI infrastructure to support real-time fraud detection and risk assessment. They need a solution that can handle both training and inference workloads while maintaining data privacy and security.
Which NVIDIA reference architecture component would be most appropriate to address the data privacy and security concerns in this AI networking setup?

  • A. NVIDIA BlueField DPUs
  • B. NVIDIA Spectrum switches
  • C. NVIDIA Magnum IO
  • D. NVIDIA CUDA-X AI libraries

Answer: A

Explanation:
NVIDIA BlueField Data Processing Units (DPUs)are integral to securing AI infrastructures, especially in environments requiring stringent data privacy and security measures. BlueField DPUs offload and accelerate critical infrastructure tasks such as encryption, firewall enforcement, and intrusion detection, thereby isolating sensitive data paths from potential threats.
In the context of AI workloads, BlueField DPUs enable secure and efficient data movement between GPUs and storage systems, ensuring that sensitive information, like financial data, is protected during both training and inference processes. Their integration into NVIDIA's reference architectures provides a hardware root of trust, essential for maintaining data integrity and compliance with security standards.

NEW QUESTION # 67
You are tasked with configuring multi-tenancy using partition key (PKey) for a high-performance storage fabric running on InfiniBand. Each tenant's GPU server is allowed to access the shared storage system but cannot communicate with another tenant's GPU server.
Which of the following partition key membership configurations would you implement to set up multi- tenancy in this environment?

  • A. Assign limited membership PKey to the shared storage system and full membership PKey to each tenant's GPU servers.
  • B. Assign full membership PKey to the shared storage system and limited membership PKey to each tenant's GPU servers.
  • C. Assign full membership to both GPU servers and storage system.
  • D. Assign limited membership to both GPU servers and storage system.

Answer: B

Explanation:
To enforce strictmulti-tenancy, where:
* Tenant A's GPUcannot talk toTenant B's GPU
* But both can accessshared storage
The correct solution is:
* Storage system # Full PKey membership
* Each tenant's GPU # Limited PKey membership
From theNVIDIA InfiniBand P_Key Partitioning Guide:
"A port with limited membership can only communicate with full members of the same PKey. It cannot communicate with other limited members, even within the same partition." This isolates tenantsfrom each other, while allowingshared access to storage.
Incorrect Options:
* Apermits tenant-to-tenant communication.
* Bisolates everything, including access to storage.
* Cprevents GPU access to storage.
