NVIDIA AI Infrastructure Sample Questions (Q11-Q16):

NEW QUESTION # 11
In a large-scale InfiniBand fabric, you need to implement a mechanism to prioritize traffic for a specific application that requires low latency and high bandwidth. You want to leverage Quality of Service (QOS) to achieve this. Which of the following steps are essential to properly configure QOS in this scenario? (Select THREE)

A. Disable Adaptive Routing (AR) to ensure that the application's traffic always takes the shortest path.
B. Mark the application's traffic with appropriate DiffServ Code Point (DSCP) values.
C. Configure VLAN tagging on the application's traffic to isolate it from other traffic.
D. Configure Weighted Fair Queueing (WFQ) or Strict Priority Queueing on the egress ports of the InfiniBand switches to prioritize the application's traffic class.
E. Map the application's traffic to a specific traffic class with appropriate priority settings within the InfiniBand switches.

Answer: B,D,E

Explanation:
Effective QOS requires traffic classification (DSCP marking), mapping to appropriate traffic classes with priority settings, and configuring queueing mechanisms (WFQ/Strict Priority Queueing) on egress ports to enforce the priority. VLAN tagging is useful for network segmentation but not directly for QOS. Disabling AR might reduce path diversity, but could also lead to congestion if the shortest path is already heavily utilized.

NEW QUESTION # 12
You are tasked with automating the BlueField OS deployment process across a large number of SmartNICs. Which of the following methods is MOST suitable for this task?

A. Utilizing a custom-built python script to flash each individual card, controlled from a central server. This method supports parallel flashing.
B. Utilizing the 'dd' command to directly copy the image to each SmartNIC's flash memory.
C. Manually flashing each SmartNIC using the 'bfboot utility on a workstation.
D. Creating a custom ISO image with the BlueField OS and booting each SmartNIC from a USB drive.
E. Using a network boot (PXE) server to deploy the BlueField OS image over the network. This allows centralized management and scalability.

Answer: E

Explanation:
PXE boot allows for automated and scalable OS deployment over the network, making it the most suitable option for managing a large number of SmartNlCs. Manually flashing or using USB drives is not practical at scale, and using 'dd' directly can be risky and error-prone without proper checks.

NEW QUESTION # 13
A data scientist reports that training performance on a DGX A100 server has significantly degraded over the past week. 'nvidia-smi' shows all GPUs functioning, but 'nvprof' reveals substantially increased 'cudaMemcpy' times. What is the MOST likely bottleneck?

A. The NVLink connections between GPUs are failing, forcing data transfers through PCle.
B. The storage system is slow, delaying data loading and preprocessing.
C. The PCle bus is saturated, limiting data transfer speeds between the CPU and GPUs.
D. The GPUs are overheating, causing thermal throttling and slower memory transfers.
E. The CPU is heavily loaded, causing contention for system memory bandwidth.

Answer: E

Explanation:
Increased ScudaMemcpy' times indicate a bottleneck in data transfer between the CPU and GPIJs or within the GPU memory itself. While PCle saturation or failing NVLink connections could contribute, a heavily loaded CPU is often the primary culprit. CPU-bound preprocessing tasks or general system load can create contention for system memory, slowing down data movement to the GPUs. The NVLink being used is less likely because 'nvidia-smi' would likely report errors or lower speeds between the GPUs

NEW QUESTION # 14
You are installing multiple NVIDIA GPUs in a server for a deep learning cluster. To optimally utilize the GPUs, which software component(s) are MANDATORY after the physical installation and driver setup? (Select TWO)

A. A deep learning framework like TensorFlow or PyTorch.
B. NVIDIA CUDA Toolkit.
C. A web browser.
D. A text editor.
E. A spreadsheet program.

Answer: A,B

Explanation:
The NVIDIA CUDA Toolkit provides the necessary libraries and tools for GPU-accelerated computing. A deep learning framework (TensorFlow or PyTorch) is required to build and train deep learning models that leverage the GPUs. While a web browser and text editor might be useful, they are not mandatory. Spreadsheet applications have no purpose here.

NEW QUESTION # 15
An InfiniBand administrator needs to run performance benchmarks on new devices added to the fabric. What tool should be used to check the latency?

A. tcpdump
B. perfmon
C. ibdiagnet
D. ib_write_lat

Answer: D

Explanation:
ib_write_lat is the InfiniBand performance benchmarking tool used to measure RDMA write latency between devices. It is the appropriate utility for checking latency on newly added InfiniBand fabric devices.
