NVIDIA AI Infrastructure 認定 NCP-AII 試験問題 (Q103-Q108):

質問 # 103
After physically installing a new NVIDIA GPU in a server, you boot the system. You notice that the GPU is not recognized by the operating system. You've verified the card is properly seated and powered. What are the MOST LIKELY causes and solutions? (Select TWO)

正解：C、D

解説：
The most common reasons for a GPU not being recognized are missing or incorrect drivers and an outdated BIOS/UEFI that doesn't support the card. A faulty PCIe slot is possible, but less likely as the initial troubleshooting step. Reinstalling the OS is rarely needed for driver issues. A defective GPU is possible but should be considered after other options are exhausted.


質問 # 104
If two ports must be connected, but one is SFP and one is QSFP, for example, to connect a 25 GbE Host Channel Adapter to a QSFP port capable of both 100 GbE and 25 GbE, which solution would best meet this requirement?

正解：B

解説：
A QSA adapter is the correct solution when an SFP-based device must connect to a QSFP port that supports the required speed mode. QSA stands for QSFP-to-SFP adapter. It allows an SFP or SFP28 transceiver or cable to be inserted into a QSFP or QSFP28 cage, assuming the switch port supports operation at the lower target speed, such as 25 GbE. This is useful in mixed-speed NVIDIA networking environments where a 25 GbE Host Channel Adapter must connect to a switch port that is physically QSFP but electrically capable of
25 GbE operation. SFP connectors alone do not solve the mechanical mismatch because they cannot directly fit into a QSFP cage. An SFP-to-1G BASE-T adapter is intended for 1 GbE copper RJ45 connectivity and does not meet a 25 GbE requirement. A QSFP-to-QSFP DAC cable also fails because the host side is SFP- based. During physical-layer management, engineers must confirm port capability, supported cable type, transceiver compatibility, link speed, and firmware support to avoid link-down conditions during cluster bring- up.


質問 # 105
You have configured MIG on your A100 GPU, creating several MIG instances. You now want to allocate a specific MIG instance to a Docker container. How would you specify the necessary device option when running the 'docker run' command to ensure the container uses only that MIG instance? Assuming the MIG instance UUID is GPU-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

正解：A

解説：
The correct way to specify a specific MIG instance for a Docker container is using the '-gpus device=' option with the MIG instance UUID. This ensures the container only has access to the designated MIG instance. '-gpus all' grants access to all GPUs. "-device=/dev/nvidiaC provides access to the entire GPU. '--runtime=nvidia' is required for NVIDIA GPU support but doesn't specify a particular instance. There is no option unvidia-visible-devices'.


質問 # 106
You encounter a situation where a container running with GPU support is experiencing significant performance degradation compared to running the same application directly on the host. You have already verified that the NVIDIA drivers are correctly installed and the NVIDIA Container Toolkit is properly configured. Which of the following could be contributing factors to this performance difference?
(Select all that apply)

正解：B、D

解説：
Using an older CUDA runtime within the container (A) can lead to performance degradation due to missing optimizations or compatibility issues with the application. Improper CPU pinning and NUMA affinity (B) can cause the container to access memory inefficiently, especially in multi-socket systems. '--ipc=host' (C) can improve performance in some cases by sharing the host's IPC namespace, but it's not always necessary and can have security implications. Kernel version differences (D) are generally handled by the NVIDIA Container Toolkit, which ensures compatibility. Insufficient bandwidth between CPU and GPU (E) might be caused by hardware issue.


質問 # 107
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?

正解：D
