NVIDIA AI Infrastructure Sample Questions (Q144-Q149):

NEW QUESTION # 144
A company has a registered NGC account and their server has NCG CLI installed. What step should be taken first to gain access to NGC?

Answer: B

Explanation:
ngc config set is the first configuration step after installing the NGC CLI. It prompts for the required NGC credentials, including the API key, and stores them so the system can authenticate and access NGC resources.


NEW QUESTION # 145
An AI training cluster with NVIDIA GPUs experiences prolonged data loading times during checkpoint reloading, causing GPUs to idle frequently. CPU utilization during data transfers remains high. Which solution most effectively optimizes storage-to-GPU throughput while reducing CPU overhead?

Answer: C

Explanation:
GPUDirect Storage is the most effective solution because it reduces unnecessary CPU involvement in the data path between storage and GPU memory. In a traditional AI data pipeline, checkpoint data may move from storage into system memory, be processed by the CPU, and then be copied into GPU memory. This creates CPU overhead and can leave GPUs idle while waiting for data. GPUDirect Storage allows compatible storage systems, file systems, drivers, and NVIDIA GPUs to transfer data more directly into GPU memory. This improves checkpoint reload performance, reduces CPU copy overhead, and helps keep GPUs saturated during training. Increasing batch size may reduce the frequency of storage access, but it does not solve the checkpoint transfer bottleneck. SATA SSDs in RAID 0 may improve local sequential throughput, but they are not ideal for distributed training or shared cluster data access. Adding more GPUs can worsen the issue if the storage path is already the bottleneck. In NVIDIA AI infrastructure, storage-to-GPU optimization is critical for large model training, checkpointing, recovery, and maintaining high accelerator utilization.


NEW QUESTION # 146
What is the primary purpose of performing a NeMo Burn-in on a new AI infrastructure?

Answer: C

Explanation:
NeMo Burn-in validates new AI infrastructure by running representative NeMo workloads under sustained load. This stresses the GPUs, networking, storage paths, drivers, containers, and software stack together to confirm the platform is reliable before production use.


NEW QUESTION # 147
During a DGX cluster deployment, what is the most effective way to verify the health and integrity of the local RAID storage array?

Answer: C

Explanation:
The correct answer is C because mdadm --examine and mdadm --detail directly inspect Linux software RAID metadata and array health. During DGX cluster deployment, local RAID storage must be verified before the node is released for AI workloads, logging, container images, datasets, scratch space, or checkpoint staging. A mounted filesystem only proves that the operating system can access the volume; it does not confirm that the RAID array is clean, synchronized, degraded, rebuilding, or free of disk failure events. FIO is useful for performance benchmarking, but speed and latency results alone do not prove RAID integrity. A degraded array can sometimes still deliver acceptable short-term performance while lacking redundancy or carrying latent errors. The mdadm --detail command reports array state, active devices, failed devices, rebuild progress, spare disks, and consistency status. The mdadm --examine command checks member-device metadata and helps confirm whether disks belong correctly to the array. In NVIDIA AI infrastructure bring- up, RAID health validation is part of server readiness because storage faults can cause job failures, lost logs, unstable container operation, or checkpoint corruption during production workloads.


NEW QUESTION # 148
ClusterKit's NCCL bandwidth test shows 350 GB/s on a 400G InfiniBand fabric. How should this result be interpreted?

Answer: A

Explanation:
A 350 GB/s NCCL bandwidth result on a 400G InfiniBand fabric indicates strong collective communication performance. This is consistent with a healthy fabric and effective GPUDirect RDMA operation during ClusterKit validation.
