NVIDIA AI Infrastructure Sample Questions (Q86-Q91):

NEW QUESTION # 86
What is the primary purpose of performing a NeMo burn-in on a new AI infrastructure?

Answer: A

Explanation:
The primary purpose of a NeMo burn-in is to stress test the hardware and software stack using representative NeMo workloads before releasing the AI infrastructure to production. NeMo workloads can exercise GPU compute, GPU memory, CUDA libraries, NCCL communication, storage access, checkpointing, container runtime, scheduler integration, and distributed training behavior. This makes NeMo burn-in more realistic than simply checking that GPUs are visible or that a small synthetic benchmark runs successfully. The goal is not to tune hyperparameters for model accuracy, because burn-in validates infrastructure reliability rather than model quality. It is also not mainly about ensuring all GPUs run at identical clock speeds; clock behavior can vary based on power, thermals, workload, and GPU boost behavior. What matters is that the workload runs reliably, without stalls, NCCL failures, GPU Xid errors, storage bottlenecks, memory faults, or unstable performance. In NVIDIA AI infrastructure validation, representative workload burn-in bridges the gap between low-level diagnostics and real production training, helping detect issues that synthetic tests alone may miss.


NEW QUESTION # 87
For an NVIDIA Enterprise AI Factory with 256 GPUs, which storage solution characteristic is most critical to validate during scaling tests?

Answer: C

Explanation:
Scaling an AI cluster to 256 GPUs (32 nodes of DGX H100) creates a massive "Incast" problem for the storage fabric. During large-scale training, every node frequently reads huge batches of data simultaneously.
NVIDIA's reference architectures (BasePOD/SuperPOD) specify that for high-performance training, each node must be able to sustain a minimum throughput-often8 GiB/s or more-to keep all 8 GPUs saturated.
If the storage system can handle one node at high speed but chokes when all 32 nodes request data, the
"Scaling Efficiency" of the AI model will drop drastically as GPUs sit idle waiting for IO. Therefore, validatingconsistent per-node throughputunder full cluster load is the most critical metric for an AI Factory.
While IOPS (Option D) are important for small files, modern AI datasets are often sharded into large binary formats (like WebDataset or TFRecord) where sequential throughput becomes the primary bottleneck.


NEW QUESTION # 88
During East-West fabric validation on a 64-GPU cluster, an engineer runs all_reduce_perf and observes an algorithm bandwidth of 350 GB/s and bus bandwidth of 656 GB/s. What does this indicate about the fabric performance?

Answer: C


NEW QUESTION # 89
You encounter an error during MIG instance creation using 'nvidia-smi' stating 'Insufficient GPU resources'. Which of the following could be the cause? (Select all that apply)

Answer: A,C,D

Explanation:
The 'Insufficient GPIJ resources' error indicates that the requested MIG instance creation cannot be fulfilled due to limitations in available resources (A) such as compute or memory. Outdated drivers (B) may not support the requested MIG configurations and hence can lead to resource management problems. When other instances or processes already consume all available resources (C), the operation can't continue. A GPU in a bad state might cause issues, but the specific error message points to resource exhaustion more directly. MIG does not bypass resource checks (E).


NEW QUESTION # 90
Which of the following storage technologies are most suitable for storing large training datasets used in deep learning, considering both performance and cost?

Answer: E

Explanation:
NVMe SSDs in a local RAID offer high performance and relatively low latency, making them suitable for data that needs to be accessed quickly. Parallel file systems deployed on NVMe SSDs provide the highest performance and scalability, especially for large datasets accessed concurrently by multiple training nodes. Object storage can be used for initial data ingest or archival but is generally slower than local or parallel file systems for training. SATA HDDs and Tape backup systems are a low performing option for this case.
