Question#1

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 CUDA-X AI libraries

B. NVIDIA Magnum IO

C. NVIDIA BlueField DPUs

D. NVIDIA Spectrum switches

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.

Question#2

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. Separated Host mode

B. NIC mode

C. DPU mode

D. Restricted mode

Explanation:
In DPU Mode, the ARM cores on Blue Fieldown the NIC data path, while still allowing the host system to access the DPU OS (via OOB or virtio).
From NVIDIA BlueField Documentation:
"In DPU Mode, the data path is offloaded to the BlueField Arm cores, enabling advanced security and networking functions, while still allowing host access to the BlueField OS."
This is different from:
NIC Mode: Data path controlled by host, ARM cores inactive.
Separated Host Mode: Complete isolation; host cannot access DPU OS.
Restricted Mode: Limited host access to DPU OS, but without full offload capabilities.

Question#3

Which of the following commands would you use to assign the IP address 20.11.12.13 to the management interface in SONiC?

A. nv set interface mgmt ip 20.11.12.13 20.11.12.254

B. interface mgmt0 vrf mgmt ip address 20.11.12.13 20.11.12.254

C. sudo config interface ip add eth0 20.11.12.13/24 20.11.12.254

D. config ip add etho 20.11.12.13/24 20.11.12.254

Explanation:
In SONiC, to assign a static IP address to the management interface, the correct command is:
sudo config interface ip add eth0 20.11.12.13/24 20.11.12.254
This command sets the IP address and the default gateway for the management interface.
SONiC (Software for Open Networking in the Cloud) is an open-source network operating system used on NVIDIA Spectrum-X platforms, including Spectrum-4 switches, to provide a flexible and scalable networking solution for AI and HPC data centers. Configuring the management interface in SONiC is a critical task for enabling remote access and network management. The question asks for the correct command to assign the IP address 20.11.12.13 to the management interface, typically identified as eth0 in SONiC, as it is the default management interface for out-of-band management.
Based on NVIDIA’s official SONiC documentation, the correct command to assign an IP address to the management interface involves using the config command-line utility, which is part of SONiC’s configuration framework. The command sudo config interface ip add eth0 20.11.12.13/24 20.11.12.254 is the standard method to configure the IP address and gateway for the eth0 management interface. This command specifies the interface (eth0), the IP address with its subnet mask (20.11.12.13/24), and the default gateway (20.11.12.254), ensuring proper network connectivity.
Exact Extract from NVIDIA Documentation:
“To configure the management interface in SONiC, use the config interface ip add command. For example, to assign an IP address to the eth0 management interface, run:
sudo config interface ip add eth0 <IP_ADDRESS>/<PREFIX_LENGTH> <GATEWAY>
Example:
sudo config interface ip add eth0 20.11.12.13/24 20.11.12.254
This command adds the specified IP address and gateway to the management interface, enabling network access.”
―NVIDIA SONiC Configuration Guide
This extract confirms that option C is the correct command for assigning the IP address to the management interface in SONiC. The use of sudo ensures the command is executed with the necessary administrative privileges, and the syntax aligns with SONiC’s configuration model, which persists the changes in the configuration database.

Question#4

You have recently implemented NVIDIA Spectrum-X in your data center to optimize AI workloads. You need to verify the performance improvements and create a baseline for future comparisons.
Which tool would be most appropriate for creating performance baseline results in this Spectrum-X environment?

A. NetQ

B. CloudAI Benchmark

C. MLNX-OS

D. Ansible

Explanation:
The CloudAI Benchmark is designed to evaluate and establish performance baselines in AI-optimized networking environments like NVIDIA Spectrum-X. It assesses various performance metrics, including throughput and latency, ensuring that the network meets the demands of AI workloads. This benchmarking is essential for validating the benefits of Spectrum-X and for ongoing performance monitoring.

Question#5

A fabric administrator added new servers to a 40-port edge switch. The administrator now needs to gather and map the newly added ports’ LIDs and LINK SPEED.
Which of the following commands can be used for that purpose?

A. ib_check_routes

B. ibnetdiscover

C. ibhosts

D. ibswitches

Explanation:
The correct utility isibnetdiscover.
From the official NVIDIA InfiniBand Utilities Guide:
"ibnetdiscover scans the fabric and returns a topology of all switches and end nodes, including their GUIDs, LIDs, port numbers, and link speeds."
It generates a fabric map with node-to-port relationships and shows:
GUIDs
LIDs (Local IDs)
Link speeds and widths
Switch-to-host connections
This is essential for network topology validation and mapping physical port additions.
Incorrect Options:
ib_check_routesC for routing table diagnostics.
ibhostsC shows host information but not switch-level port mapping.
ibswitchesC shows switch info, but lacks port-level LID/link speed mapping.
