NVIDIA-Certified Professional AI Networking Sample Questions (Q21-Q26):

NEW QUESTION # 21
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 limited membership to both GPU servers and storage system.
D. Assign full 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.

NEW QUESTION # 22
You need to configure a bond in Cumulus Linux. Which command should you use?

A. nv set interface bond1 bond member swp1-4
B. nv set interface bond1 bond mode lacp
C. nv set interface bond1 bond mlag enable
D. nv set bondbond1 interface member swp1-4

Answer: B

Explanation:
In Cumulus Linux, configuring a bond interface with Link Aggregation Control Protocol (LACP) involves setting the bond mode to 'lacp'. The correct command to achieve this is:
nv set interface bond1 bond mode lacp
This command sets the bonding mode of 'bond1' to LACP, enabling dynamic link aggregation for increased bandwidth and redundancy.
Reference Extracts from NVIDIA Documentation:
* "To reset the link aggregation mode for bond1 to the default value of 802.3ad, run the nv set interface bond1 bond mode lacp command."

NEW QUESTION # 23
Which component of the Spectrum-X platform is responsible for reordering out-of-order packets?

A. NetQ
B. DOCA software
C. SuperNIC
D. Spectrum-4 switch

Answer: C

Explanation:
Within the Spectrum-X platform, the NVIDIA BlueField-3 SuperNIC is responsible for reordering out-of- order packets. When RoCE adaptive routing is employed, packets may arrive at their destination out of order due to dynamic path selection. The BlueField-3 SuperNIC handles this by reassembling the packets in the correct order at the transport layer, ensuring that the application receives data seamlessly.
Reference Extracts from NVIDIA Documentation:
* "As different packets of the same flow travel through different paths of the network, they may arrive out of order to their destination. At the RoCE transport layer, the BlueField-3 DPU takes care of the out- of-order packets and forwards the data to the application in order."
* "The BlueField-3 SuperNIC offers adaptive routing, out-of-order packet handling and optimized congestion control." The NVIDIA Spectrum-X networking platform is an Ethernet-based solution optimized for AI workloads, combining Spectrum-4 switches, BlueField-3 SuperNICs, and software like DOCA and NetQ to deliver high performance, low latency, and efficient data transfer. A key feature of Spectrum-X is its adaptive routing, which dynamically selects the least-congested paths for packet transmission to maximize bandwidth and minimizelatency. However, this per-packet load balancing can result in packets arriving out of order at the destination, necessitating a mechanism to reorder them for seamless application performance. The question asks which Spectrum-X component is responsible for reordering these out-of-order packets.
According to NVIDIA's official documentation, theBlueField-3 SuperNICis the component responsible for reordering out-of-order packets in the Spectrum-X platform. The SuperNIC, a network accelerator designed for hyperscale AI workloads, handles packet reordering at the RDMA over Converged Ethernet (RoCE) transport layer. It uses its processing capabilities to transparently reorder packets and place them in the correct sequence in the host memory, ensuring that adaptive routing's out-of-order delivery is invisible to the application. This is critical for maintaining predictable performance in AI workloads, particularly for GPU-to- GPU communication in Spectrum-X networks.
Exact Extract from NVIDIA Documentation:
"The Spectrum-4 switches are responsible for selecting the least-congested port for data transmission on a per- packet basis. As different packets of the same flow travel through different paths of the network, they may arrive out of order to their destination. The BlueField-3 SuperNIC transforms any out-of-order data at the RoCE transport layer, transparently delivering in-order data to the application."
-NVIDIA Technical Blog: Turbocharging Generative AI Workloads with NVIDIA Spectrum-X Networking Platform This extract confirms that option A, the SuperNIC (specifically the BlueField-3 SuperNIC), is the correct answer. The SuperNIC's role in reordering packets ensures that the adaptive routing implemented by Spectrum-4 switches does not compromise application performance, maintaining high effective bandwidth and low tail latency for AI workloads.

NEW QUESTION # 24
What does NetQ leverage (in addition to NVIDIA "What Just Happened" switch telemetry data and NVIDIA DOCA telemetry) to help network operators proactively identify server and application root cause issues?

A. Application telemetry
B. Packet capture telemetry
C. Flow telemetry
D. Behavioral telemetry

Answer: D

Explanation:
NetQintegrates multiple telemetry sources, includingWJH,DOCA, and notably,Behavioral Telemetry.
From theNetQ Documentation - Behavioral Telemetry Section:
"Behavioral telemetry in NetQ correlates server and application behavior with network events, offering insights into root cause analysis by detecting anomalies in protocol, path, or performance behavior." This helps identify patterns like:
* Misbehaving applications causing retransmits.
* Sudden changes in traffic flows.
* Latency spikes correlated with app-level issues.
It complements device-level telemetry by introducingintent-based anomaly detection, crucial for proactive operations.
Incorrect Options:
* Flow telemetryandpacket captureoffer raw data but not behavioral insights.
* Application telemetryis too vague and is not the term NetQ uses for this feature.
Reference: NetQ 3.2 Documentation - Behavioral Telemetry

NEW QUESTION # 25
What is the basic functionality of an IB Router?

A. Connecting two (or more) InfiniBand fabrics
B. Connecting NVLink domains to an InfiniBand fabric
C. Connecting Ethernet switches to an InfiniBand fabric
D. Connecting SAN to an InfiniBand fabric

Answer: A

Explanation:
AnInfiniBand (IB) Routerconnects two or moreInfiniBand subnets, making it possible for nodes in different subnets to communicate throughroute-managed communication.
From the officialNVIDIA InfiniBand Routers Documentation:
"An InfiniBand router provides connectivity between two or more InfiniBand subnets, enabling communication between hosts that are not on the same subnet while preserving isolation and scalability."
* Ensures fabric scalability by allowing subnet segmentation.
* Uses LID routing across subnet managers (SMs).
* Essential in large clusters with thousands of nodes.
Incorrect Options:
* AandBare incorrect: InfiniBand does not connect directly to Ethernet or SANs without a gateway.
* Cis unrelated: NVLink is a GPU interconnect, not tied to InfiniBand routers.
Reference: NVIDIA InfiniBand Routers Guide
