NVIDIA AI Infrastructure Sample Questions (Q233-Q238):

NEW QUESTION # 233
You are running a distributed training job on a multi-GPU server. After several hours, the job fails with a NCCL (NVIDIA Collective Communications Library) error. The error message indicates a failure in inter-GPU communication. 'nvidia-smi' shows all GPUs are healthy. What is the MOST probable cause of this issue?

  • A. A faulty network cable connecting the server to the rest of the cluster.
  • B. Incorrect NCCL configuration, such as an invalid network interface or incorrect device affinity settings.
  • C. Insufficient inter-GPU bandwidth; reduce the batch size to decrease communication overhead.
  • D. Driver incompatibility issue between NCCL and the installed NVIDIA driver version.
  • E. A bug in the NCCL library itself; downgrade to a previous version of NCCL.

Answer: B,D

Explanation:
NCCL errors during inter-GPU communication often stem from configuration issues (B) or driver incompatibilities (E). Incorrect network interface or device affinity settings can prevent proper communication. Driver versions might not fully support the NCCL version being used. Reducing batch size (C) might alleviate symptoms but doesn't address the root cause. A faulty network cable (D) would likely cause broader network issues beyond NCCL. Downgrading NCCL (A) is a potential workaround but not the ideal first step.


NEW QUESTION # 234
You are setting up a multi-GPU AI server for deep learning. You want to ensure optimal inter-GPU communication. Which of the following interconnect technologies would provide the BEST performance?

  • A. NVLink
  • B. Infiniband
  • C. PCle Gen4 x16
  • D. PCle Gen3 x16
  • E. Ethernet

Answer: A

Explanation:
NVLink is designed specifically for high-bandwidth, low-latency inter-GPU communication, offering significantly better performance than PCIe or network connections for workloads that benefit from it. InfiniBand is suitable for node to node communication, while NVLink is for GPU to GPU on the same node.


NEW QUESTION # 235
You are configuring a BlueField-3 DPLJ for a cloud-native application using Kubernetes. You want to offload container networking using OVS (Open vSwitch). Which of the following configuration steps are NECESSARY to integrate the BlueField-3 DPIJ with the Kubernetes cluster for network offload? (Select TWO)

  • A. Configure the BlueField DPIJ to act as a DHCP server for the Kubernetes pods.
  • B. Manually create OVS bridges and vPorts on the BlueField DPU using 'ovs-vsctr.
  • C. Install the Mellanox OFED drivers on all Kubernetes worker nodes.
  • D. Configure the Kubernetes CNI (Container Network Interface) to use the OVS bridge managed by the BlueField DPIJ.
  • E. Deploy the NVIDIA BlueField Kubernetes Operator to manage the DPIJ lifecycle and networking configurations.

Answer: D,E

Explanation:
The NVIDIA BlueField Kubernetes Operator is essential for automating the management and configuration of the DPIJ within the Kubernetes environment. This includes creating and managing OVS bridges. Integrating the Kubernetes CNI to use the OVS bridge managed by the BlueField DPIJ allows pod networking traffic to be offloaded to the DPU. Installing Mellanox OFED everywhere isn't needed with the operator. While you could manually create the bridges (E), the operator is the preferred method. The DPIJ acting as a DHCP server (D) is not a requirement for simple network offload.


NEW QUESTION # 236
Which of the following methods are considered the most reliable ways to install NVIDIA drivers on a production server running a stable Linux distribution (e.g., RHEL, CentOS, or Ubuntu LTS) to minimize downtime and ensure system stability?

  • A. Utilizing NVIDIA's container toolkit and running all A1 workloads inside containers to isolate the driver dependencies.
  • B. Using NVIDIA's data center driver program.
  • C. Downloading and running the latest .run' installer from the NVIDIA website without any package manager integration.
  • D. Using the distribution's package manager (e.g., 'apt' , 'yum' , or 'dnf) to install NVIDIA drivers from the official or curated repositories.
  • E. Building custom NVIDIA driver packages from source code to match the specific kernel version and system libraries.

Answer: A,B,D

Explanation:
Using the distribution's package manager is generally the safest and most reliable method for installing NVIDIA drivers. This approach ensures that dependencies are managed correctly and updates are handled through the system's standard update mechanisms. Containerization isolates the driver and application dependencies. Nvidia's data center driver program provides enterprise-grade support and reliability. Running the .run installer directly can sometimes lead to dependency issues and conflicts. Building from source is complex and not generally recommended for production environments.


NEW QUESTION # 237
Your AI training workload involves a large dataset stored in an object storage system (like AWS S3). You notice that fetching data directly from S3 during training is a bottleneck. Which of the following strategies can significantly improve data loading performance?

  • A. Increase the number of S3 request retries
  • B. Use S3 Glacier for data storage.
  • C. Reduce the number of concurrent data loaders
  • D. Switch to a different object storage provider
  • E. Use a caching layer (e.g., using Alluxio or JuiceFS) to cache frequently accessed data locally or on faster storage

Answer: E

Explanation:
A caching layer brings frequently accessed data closer to the compute nodes, reducing latency and improving throughput. Increasing retries only addresses transient errors. Reducing data loaders worsens performance. Switching providers might not solve the underlying latency issue. S3 Glacier is for archival, so will result in worse performance.
