Question 1 of 111

As the network administrator for a large-scale AI research cluster, you are responsible for ensuring seamless data flow across an InfiniBand east-west fabric that interconnects hundreds of compute nodes.
Which tool would you use to trace and discover the network paths between nodes on this InfiniBand east-west fabric?
Answer choices
Show answer

Correct answer: B

ibpathverify traces and verifies InfiniBand paths between source and destination nodes, making it suitable for validating east-west connectivity in a large compute fabric. It checks the path records and forwarding behavior used by the InfiniBand subnet, helping identify routing or topology issues. tracert is intended for IP networks, while ibnetdiscover focuses on discovering and displaying InfiniBand topology rather than verifying specific paths.

Question 2 of 111

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?
Answer choices
Show answer

Correct answer: A

CloudAI Benchmark creates repeatable performance measurements for AI infrastructure, allowing administrators to establish a baseline after deploying Spectrum-X. It measures workload and network behavior relevant to distributed AI training and inference, making later comparisons meaningful when configurations or workloads change. MLNX-OS is a switch operating system, Ansible automates configuration tasks, and NetQ provides network visibility and validation rather than benchmark baseline testing.

Question 3 of 111

You are designing a new AI data center for a research institution that requires high-performance computing for large-scale deep learning models. The institution wants to leverage NVIDIA’s reference architectures for optimal performance.
Which NVIDIA reference architecture would be most suitable for this high-performance AI research environment?
Answer choices
Show answer

Correct answer: A

NVIDIA DGX SuperPOD is designed as a scalable, high-performance AI infrastructure for training and running large-scale deep learning workloads. It combines DGX systems, high-speed NVIDIA networking, storage, and validated reference designs into an integrated AI data center architecture. This makes it well suited to a research institution that needs maximum performance for demanding HPC and model-training workloads. DGX Cloud provides hosted capacity, while Base Command and LaunchPad focus on AI operations and access rather than the underlying data center reference architecture.

Question 4 of 111

In an AI cluster using NVIDIA GPUs, which configuration parameter in the NicClusterPolicy custom resource is crucial for enabling high-speed GPU-to-GPU communication across nodes?
Answer choices
Show answer

Correct answer: A

The OFED Driver parameter enables installation and configuration of NVIDIA’s networking drivers required for high-performance InfiniBand or RoCE communication. These drivers provide the RDMA capabilities that allow GPUs on different nodes to exchange data with low latency and high bandwidth. RDMA Shared Device Plugin exposes RDMA resources to workloads, but it depends on the underlying OFED driver being installed and operational.

Question 5 of 111

Which tool would you use to gather telemetry data in a SpectrumX network?
Answer choices
Show answer

Correct answer: C

NVIEW is used to gather telemetry data in a SpectrumX network. It collects and exposes network performance and state information, enabling monitoring and analysis of the AI fabric. UFM is primarily associated with InfiniBand fabric management, while NetQ focuses on NVIDIA Ethernet network operations rather than the SpectrumX telemetry collection function.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.

I don't usually leave reviews, but this one felt worth sharing. The questions were quite close to what actually appeared on the exam, more than I expected. I spent about a week going through the material before my test, and it helped me feel more prepared.
Remi Nuyts
United States
Passed ITIL 4 Foundation with 87%. Material was enough by itself.
Archie Hopkins
United States
I had a smooth experience from start to finish. Access was available right away, no technical issues, which made it easy to get started. The content felt relevant and aligned well with what I was looking for.
Nancy Mcbride
United States
Does what it says it does. Content felt solid, nothing confusing to navigate and I didn't run into any weird issues. I been putting off scheduling the exam for a while and going through this gave me enough confidence to finally book it and pass.
Neil Savage
United States
A very quick response was received via email when a link issue occurred. The study materials provided were high quality and extremely helpful. I was able to complete the test successfully. Many thanks for the excellent support.
