NVIDIA-Certified Professional AI Networking Sample Questions (Q19-Q24):

NEW QUESTION # 19
You have implemented adaptive routing in your Spectrum-X network to optimize AI workload performance.
You need to verify the effectiveness of this configuration and monitor its impact on network congestion.
Which tool would be most appropriate for monitoring and analyzing the adaptive routing performance in your Spectrum-X environment?

  • A. Ansible
  • B. MLNXOS
  • C. CloudAI Benchmark
  • D. NetQ

Answer: D

Explanation:
NVIDIA NetQ is a comprehensive network operations tool designed to provide real-time visibility into the health and performance of NVIDIA networking environments, including Spectrum-X. It offers detailed telemetry and analytics, allowing administrators to monitor adaptive routing behaviors, detect congestion, and analyze traffic patterns. By leveraging NetQ, you can ensure that adaptive routing is functioning as intended and that the network is optimized for AI workloads.
Reference Extracts from NVIDIA Documentation:
* "The NVIDIA NetQ network validation and ASIC monitoring tool set provide visibility into the network health and behavior. The NetQ flow telemetry analysis shows the paths that data flows take as they traverse the network, providing network latency and performance insights."
* "By leveraging telemetry from Spectrum Ethernet switches and BlueField-3 SuperNICs, NVIDIA NetQ can detect network issues proactively and troubleshoot network issues faster for optimal use of network capacity."


NEW QUESTION # 20
When upgrading Cumulus Linux to a new version, which configuration files should be migrated from the old installation?
Pick the 2 correct responses below.

  • A. All files in /etc/network
  • B. All files in /etc/cumulus/acl
  • C. All files in /etc/mix
  • D. All files in /etc

Answer: A,B

Explanation:
Before upgrading Cumulus Linux, it's essential to back up configuration files to a different server. The /etc directory is the primary location for all configuration data in Cumulus Linux. Specifically, the following files and directories should be backed up:
* /etc/frr/ - Routing application (responsible for BGP and OSPF)
* /etc/hostname - Configuration file for the hostname of the switch
* /etc/network/ - Network configuration files, most notably /etc/network/interfaces and /etc/network
/interfaces.d/
* /etc/cumulus/acl - Access control list configurations
Cumulus Linux is a network operating system used on NVIDIA Spectrum switches, including those in the Spectrum-X platform, to provide a Linux-based environment forEthernet networking in AI and HPC data centers. When upgrading Cumulus Linux to a new version, it's critical to migrate specific configuration files to preserve network settings and ensure continuity. The question asks for the two configuration file locations that should be migrated from the old installation during an upgrade.
According to NVIDIA's official Cumulus Linux documentation, the key directories containing configuration files that should be migrated during an upgrade are /etc/cumulus/acl (for access control list configurations) and /etc/network (for network interface configurations). These directories store critical network settings that define the switch's behavior, such as ACL rules and interface settings, which must be preserved to maintain network functionality after the upgrade.
Exact Extract from NVIDIA Documentation:
"When upgrading Cumulus Linux, you must back up and migrate specific configuration files to ensure continuity of network settings. The following directories should be included in the backup:
* /etc/cumulus/acl: Contains access control list (ACL) configuration files that define packet filtering and security policies.
* /etc/network: Contains network interface configuration files, such as interfaces and ifupdown2 settings, which define the network interfaces and their properties.Back up these directories before upgrading and restore them after the new version is installed to maintain consistent network behavior."-NVIDIA Cumulus Linux Upgrade Guide This extract confirms that options A and B are the correct answers, as /etc/cumulus/acl and /etc/network contain essential configuration files that must be migrated during a Cumulus Linux upgrade. These files ensure that ACL policies and network interface settings are preserved, which are critical for Spectrum-X configurations in AI networking environments.

NEW QUESTION # 21
What are two methods for accessing the operating system on a BlueField DPU?
Pick the 2 correct responses below

  • A. Via rshim over a USB connection on the host
  • B. Via the networking interfaces (data ports) in NIC mode
  • C. Via the rshim interface over the PCIe bus
  • D. Via the Redfish API

Answer: A,C

Explanation:
Accessing theBlueField DPU Operating System (OS)is possible throughrshim, either over PCIe or USB, and viaSSH through the OOB interfacewhen in DPU mode.
From theNVIDIA BlueField Software Documentation:
"You can access the BlueField OS through the rshim interface. The rshim module enables host-to-DPU communication either via PCIe (default) or USB."
* B. rshim over PCIe: Default when BlueField is installed in a host.
* D. rshim over USB: Useful for provisioning or systems without PCIe drivers.
Incorrect Options:
* A (NIC mode): BlueField acts as a transparent NIC; OS access is not available to the host.
* C (Redfish): Redfish is for out-of-band management, not direct OS-level access.

NEW QUESTION # 22
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. ibnetdiscover
  • B. ibhosts
  • C. ibswitches
  • D. ib_check_routes

Answer: A

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_routes- for routing table diagnostics.
* ibhosts- shows host information but not switch-level port mapping.
* ibswitches- shows switch info, but lacks port-level LID/link speed mapping.
Reference: NVIDIA InfiniBand Tools - ibnetdiscover Utility

  • C. Cumulus 5.x and later / Spectrum-2 and later / LCM enabled
  • D. Cumulus 5.x and later / Spectrum-2 and later / On-premises deployment

Answer: C

Explanation:

* Cumulus Linux Version: NetQ Flow Analysis requires Cumulus Linux 5.x or later.
* Switch Hardware: The feature is supported on Spectrum-2 and later switch models.
* Lifecycle Management (LCM): LCM must be enabled to utilize Flow Analysis capabilities.
These requirements ensure compatibility and proper functioning of the Flow Analysis feature within NetQ.
