NVIDIA AI Infrastructure 認定 NCP-AII 試験問題 (Q82-Q87):

質問 # 82
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?

A. Critical failure; bus bandwidth exceeds hardware capabilities.
B. Suboptimal performance; algorithm bandwidth should match bus bandwidth.
C. Optimal performance; bus bandwidth near theoretical peak for NDR InfiniBand.
D. Inconclusive; rerun with point-to-point tests.

正解：C

質問 # 83
After updating to a Docker version post 19.03, a data scientist attempts to run a container designed for GPU-accelerated applications with the following command:

This generates the following error (output might differ slightly depending on the specific version):

What will fix the problem?

A. The DOCA driver needs to be installed
B. Use an NGC TensorFlow container
C. The NVIDIA driver should be re-installed
D. Add the argument "--gpus all" to the docker command

正解：D

解説：
Docker 19.03 and later uses the native --gpus flag to expose NVIDIA GPUs to containers through the NVIDIA Container Toolkit. Adding --gpus all allows the container to access all available GPUs and resolves the issue where the NVIDIA driver is not detected inside the container.

質問 # 84
You are configuring a server with NVIDIA GPUs for optimal power efficiency. You want to leverage NVIDIA's power management features to minimize energy consumption during idle periods. Which of the following actions would be the MOST effective in achieving this goal, without significantly impacting performance during active workloads?

A. Remove one or more GPUs from the server to reduce overall power consumption.
B. Set a very low static power limit for the GPUs, significantly restricting their performance even during active workloads.
C. Enable NVIDIA's Adaptive Clocking and Power Limiting features, allowing the GPU to dynamically adjust its clock speeds and power consumption based on the workload.
D. Disable all GPU power management features to ensure maximum performance at all times.
E. Reduce the GPU's clock speeds to the lowest possible setting, regardless of workload.

正解：C

解説：
Enabling NVIDIA's Adaptive Clocking and Power Limiting features is the MOST effective approach. These features allow the GPU to dynamically adjust its clock speeds and power consumption based on the workload, minimizing energy consumption during idle periods while maximizing performance during active workloads. Setting a fixed low clock speed (A) or power limit (E) would severely impact performance. Disabling power management (C) wastes energy. Removing GPUs (D) reduces performance capacity.

質問 # 85
Your tasked with updating both NVIDIA GPU drivers and DOCA drivers on a set of servers used for AI workloads. The environment previously had an older driver stack and custom kernel modules. What is the most important step to successfully upgrade the drivers without causing conflicts?

A. Uninstall all existing GPU and DOCA-related drivers and associated kernel modules before the new install.
B. Validate the driver version post-install since the fresh install will overwrite the legacy drivers.
C. Keep the older driver running alongside the new version in case you need to roll back the upgrade.
D. Update the GPU driver leaving the DOCA and OFED drivers unchanged as long as they are detecting the hardware properly.

正解：A

解説：
NVIDIA AI infrastructure relies on a tightly coupled stack involving the GPU driver and theDOCA (Data Center Infrastructure-on-a-Chip Architecture)drivers, which include the OFED stack for InfiniBand.
When upgrading from an older version, "residue" from previous installations or custom kernel modules can cause version mismatches or symbol errors, preventing the new drivers from loading. The "100% verified" best practice is to perform a clean installation. This involves completely uninstalling the existing drivers (using apt-get purge or the .run file's --uninstall flag) and ensuring that kernel modules are removed from memory. This prevents conflict between the legacy nvidia.ko and the new version. Once the system is "clean," the new DOCA and GPU drivers can be installed as a matched set, ensuring that features like GPUDirect RDMA function correctly without being hindered by legacy configuration files.

質問 # 86
You are designing an Ai server infrastructure using NVIDIA HGX AIOO modules. The server's power supply units (PSUs) are configured in a redundant (N+1) setup. The individual PSUs are rated for 3000W each, and the server contains three PSUs. If the expected peak power consumption of the HGX A100 modules and other components is 5500W, what is the safety margin (in Watts) in the power budget?

A. 0W
B. 3500W
C. 5000W
D. 9000W
E. 500W

正解：E

解説：
With N+1 redundancy and three 3000W PSUs, the total available power is 2 3000W = 6000W (N+1 means the system can tolerate one PSU failure). The safety margin is 6000W - 5500W = 500W.
