NVIDIA AI Infrastructure Sample Questions (Q114-Q119):

NEW QUESTION # 114
An A1 inferencing server, using NVIDIA Triton Inference Server, experiences intermittent crashes under peak load. The logs reveal CUDA out-of-memory errors (00M) despite sufficient system RAM. You suspect a GPU memory leak within one of the models. Which strategy BEST addresses this issue?

A. Upgrade the GPUs to models with larger memory capacity.
B. Implement CUDA memory pooling within the Triton Inference Server configuration to reuse memory allocations efficiently.
C. Disable other models running on the same GPU to free up memory.
D. Reduce the batch size and concurrency of the offending model in the Triton configuration.
E. Increase the system RAM to accommodate the growing memory footprint.

Answer: B,D

Explanation:
Options B and C directly address the 00M issue. CUDA memory pooling enables efficient reuse of GPU memory, minimizing allocations and deallocations. Reducing batch size and concurrency decreases the memory footprint of the model, alleviating the pressure on GPU memory. While upgrading GPUs (D) is a solution, it is more costly than optimizing the current configuration. Increasing system RAM (A) does not solve GPU memory issues. Disabling other models (E) reduces load but doesn't address the core problem of the memory leak in the first place.

NEW QUESTION # 115
You are leading a project to enhance the energy efficiency of a data center that heavily relies on AI workloads. NVIDIA suggests moving beyond traditional metrics like Power Usage Effectiveness (PUE) to better capture the efficiency of modern data centers. Which strategy should you prioritize?

A. Develop benchmarks tailored to specific workloads, such as MLPerf for AI applications, to better understand energy use in real-world scenarios.
B. Use watts used as the primary measure of efficiency, as it accurately reflects the power input at any given time.
C. Focus on integrating kilowatt-hours into existing metrics to better reflect the actual energy used for productive work.
D. Use Power Usage Effectiveness as the primary metric while supplementing it with additional measures of useful work done per unit of energy.

Answer: A

Explanation:
Traditional data center metrics like PUE (Power Usage Effectiveness) only measure how much energy is
"wasted" by cooling and power delivery relative to the IT load; they say nothing about how efficiently that IT load is performing its task. In an AI Factory, "Efficiency" is better defined by the amount of AI training or inference performed per watt. NVIDIA advocates for the use of workload-specific benchmarks, such as MLPerf, to quantify this. MLPerf measures the time and energy required to complete standardized AI tasks (like training a ResNet-50 model or an LLM). By prioritizing these benchmarks (Option C), an organization can compare the energy efficiency of different hardware architectures (e.g., A100 vs. H100) or different software optimizations (e.g., FP8 vs. FP16). For example, even if an H100 system draws more peak power than an older system, its ability to complete a training job 9x faster results in a significantly lower "Total Energy Consumed per Job". This shift from "infrastructure efficiency" (PUE) to "computing efficiency" (MLPerf-per-watt) is essential for modern AI data centers aiming for sustainability and cost-effective scaling.

NEW QUESTION # 116
An administrator needs to perform a comprehensive pre-production stress test on a DGX H100 system. Which command validates GPU, CPU, memory, and storage components while following NVIDIA's recommended procedure?

A. ./gpu_burn 60
B. nvidia-smi -q | grep "GPU Stress Test"
C. sudo nvsm stress-test --force
D. stress --cpu $(nproc) --io $(nproc) --timeout 600

Answer: C

Explanation:
sudo nvsm stress-test --force runs NVIDIA's recommended DGX system stress validation through NVSM. It exercises key hardware components, including GPUs, CPUs, memory, and storage, making it appropriate for comprehensive pre-production health and stability testing.

NEW QUESTION # 117
You are managing a cluster of GPU servers for deep learning. You observe that one server consistently exhibits high GPU temperature during training, causing thermal throttling and reduced performance. You've already ensured adequate airflow. Which of the following actions would be MOST effective in addressing this issue?

A. Lower the GPU power limit using 'nvidia-smi -power-limit*.
B. Increase the fan speed of the GPU cooler using 'nvidia-smi --fan'.
C. Reduce the ambient temperature of the data center.
D. Update the NVIDIA drivers to the latest version.
E. Re-seat the GPU in its PCle slot to ensure proper contact and heat dissipation.

Answer: B,E

Explanation:
Re-seating the GPU (D) ensures a proper connection between the GPU and the motherboard, which is crucial for effective heat dissipation. Increasing fan speed (E) can directly improve cooling. Lowering the power limit (B) reduces temperature but also reduces performance. Updating drivers (C) may help in some cases, but it is less likely to solve a thermal throttling problem. Lowering the ambient temperature (A) is generally beneficial but might not be specific enough to fix the overheating issue on a single server.

NEW QUESTION # 118
After deploying BlueField OS, you notice that the network interfaces are not automatically configured with IP addresses. Which of the following actions would be the MOST appropriate first step to troubleshoot this issue?

A. Reinstall the Mellanox OFED drivers. A corrupted driver installation could cause network configuration issues.
B. Re-flash the Bluefield OS image
C. Manually assign static IP addresses to the interfaces using the 'ifconfig' command.
D. Check the DHCP client configuration to ensure it is enabled and properly configured to request IP addresses. Examine the logs for any errors.
E. Restart the networking service using 'systemctl restart networking'.

Answer: D

Explanation:
In most modern systems, network interfaces are automatically configured using DHCP. Therefore, the first step is to check if the DHCP client is enabled and configured correctly. If DHCP fails, then other troubleshooting steps, such as static IP assignment or driver reinstallation, can be considered.
