NVIDIA-Certified Professional AI Networking Sample Questions (Q33-Q38):

NEW QUESTION # 33
A leading AI research center is upgrading its infrastructure to support large language model projects.
The team is debating whether to implement a dedicated storage fabric for their AI workloads.
Which of the following best explains why a dedicated storage fabric is crucial for this AI network architecture?
Pick the 2 correct responses below

A. To reduce the overall cost of the storage infrastructure.
B. To ensure data security and isolation from other network traffic.
C. To enable parallel data access and improve storage performance for distributed AI workloads.
D. To provide high-bandwidth, low-latency data access that prevents I/O bottlenecks during AI model training.

Answer: C,D

Explanation:
Modern AI training (especially with LLMs) requires extremely high-speed, parallel access to large datasets. A dedicated storage fabricseparates data I/O traffic from the training compute path and avoids contention.
FromNVIDIA DGX Infrastructure Reference Architectures:
"Dedicated storage networks eliminate I/O bottlenecks by providing low-latency, high-bandwidth access to distributed storage for large-scale training jobs."
"Parallel access to datasets is key for performance, especially in multi-node, multi-GPU AI clusters." Security (B)is important, but not the core reason for a storage fabric.
Cost (D)is typicallyincreased, not reduced, with dedicated fabrics.

NEW QUESTION # 34
How is congestion evaluated in an NVIDIA Spectrum-X system?

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

Answer: B

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 # 35
When designing a multi-tenancy East/West (E/W) fabric using Unified Fabric Manager (UFM), which method should be used?

A. VXLAN
B. ROMA
C. Partition / PKey
D. VLAN

Answer: C

Explanation:
In InfiniBand networks,Partitioning using Partition Keys (PKeys)is the standard method for implementing multi-tenancy and traffic isolation. PKeys allow administrators to define logical partitions within the fabric, ensuring that traffic is confined to designated groups of nodes. This mechanism is essential for creating secure and isolated environments in multi-tenant architectures.
The Unified Fabric Manager (UFM) leverages PKeys to manage these partitions effectively, enabling administrators to assign and control access rights across different tenants. This approach ensures that each tenant's traffic remains isolated, maintaining both security and performance integrity within the shared fabric.

NEW QUESTION # 36
Which of the following routing protocols is not capable of avoiding credit loops?

A. MINHOP
B. FAT TREE
C. All routing protocols are capable of avoiding credit loops
D. UPDOWN

Answer: A

Explanation:
TheMINHOProuting protocol, while efficient in finding minimal paths, does not inherently prevent credit loops. This can lead to deadlocks in the network. In contrast, routing protocols like UPDOWN and FAT TREE are designed to avoid such loops, ensuring more reliable network operation.

NEW QUESTION # 37
When upgrading DOCA on a BlueField DPU, what command should first be run on the host?

A. sudo apt-get autoremove
B. sudo apt-get upgrade doca
C. /usr/sbin/ofed_uninstall.sh -force
D. sudo apt-get install doca

Answer: C

Explanation:
Before upgrading the DOCA SDK on aBlueField DPU, it ismandatory to uninstall the existing OFED driversto prevent compatibility conflicts.
From theNVIDIA DOCA Installation Guide:
"Before upgrading DOCA or BlueField-related software, you must remove existing OFED packages using: /usr/sbin/ofed_uninstall.sh -force." This ensures:
* Clean driver state
* No residual kernel modules or userspace libraries
* Proper registration of new DOCA/OFED versions
Incorrect Options:
* AandCmay not resolve conflicts.
* Dinstalls but doesn't remove conflicting packages.
