NVIDIA AI Infrastructure 認定 NCP-AII 試験問題 (Q59-Q64):

質問 # 59
You need to verify the NVLink connectivity between GPUs in a DGX server. Which command-line utility is the MOST reliable and provides detailed NVLink status?

A. Ispci
B. gpustat
C. nvidia-smi
D. dcgmi diag -t 1004
E. nvlink_info (Hypothetical command)

正解：D

解説：
'dcgmi diag -t 1004' is the correct command. 'nvidia-smi' provides basic GPIJ information, but 'dcgmi diag -t 1004' (part of the Data Center GPU Manager) provides specific diagnostic tests for NVLink connectivity. 'Ispci' lists PCle devices, not specifically NVLink. 'gpustat' is a monitoring tool. 'nvlink_info' is hypothetical.

質問 # 60
You are deploying an NVIDIA-Certified A1 server. The documentation specifies a minimum airflow requirement for the GPUs. How would you BEST monitor the GPU temperatures and ensure the airflow is adequate during a stress test?

A. Use 'nvidia-smi' to monitor GPU temperature and visually inspect the fans.
B. Measure the ambient temperature around the server.
C. Use a thermal camera to measure the GPU heatsink temperature.
D. Use IPMI sensors to monitor GPU temperature and fan speeds.
E. Use a software utility like 'psensor' to monitor GPU temperature.

正解：D

解説：
IPMI provides remote monitoring of hardware sensors, including GPU temperature and fan speeds, allowing you to ensure the cooling system is working correctly during a stress test. 'nvidia-smi' gives the GPU temp but not the fan speed. Ambient temperature isn't an accurate reflection of the GPU's actual temperature.

質問 # 61
During cluster deployment, the UFM Cable Validation Tool reports "Wrong-neighbor" errors on multiple InfiniBand links. What is the most efficient way to resolve this issue?

A. Reboot all leaf switches to force LLDP rediscovery.
B. Disable FEC on all switches to bypass neighbor validation.
C. Replace all affected cables with higher-grade OM5 fiber optics.
D. Verify LLDP data against topology files and remediate.

正解：D

解説：
In large-scale InfiniBand fabrics, such as those in NVIDIA DGX SuperPODs, maintaining an exact cabling topology is mandatory for theAdaptive RoutingandFat-Treealgorithms to function correctly. A "Wrong- neighbor" error occurs when the Unified Fabric Manager (UFM) detects that a cable is connected to a port other than the one specified in the master topology map (often a .csv or .topology file). UFM uses LLDP (Link Layer Discovery Protocol) or Subnet Management packets to identify the GUIDs on both ends of a link.
The most efficient remediation is to cross-reference the live LLDP data provided by UFM with the intended design. This allows the engineer to identify if the error is a physical mis-cabling (swapped ports) or a logical error in the topology file. Rebooting switches (Option A) will not fix a physical patch error, and disabling FEC (Option D) would lead to catastrophic signal loss on 400G (NDR) links without addressing the underlying routing logic issue. Correcting the physical patch or updating the topology file ensures the fabric's
"Ground Truth" is restored.

質問 # 62
You're designing a new InfiniBand network for a distributed deep learning workload. The workload consists of a mix of large-message all- to-all communication and small-message parameter synchronization. Considering the different traffic patterns, what routing strategy would MOST effectively minimize latency and maximize bandwidth utilization across the fabric?

A. Implement a static routing scheme with manually configured forwarding tables on each switch.
B. Rely solely on the default Subnet Manager (SM) with a Min Hop path selection algorithm.
C. Utilize a combination of Adaptive Routing (AR) to handle dynamic traffic patterns and Quality of Service (QOS) to prioritize small-message parameter synchronization.
D. Disable multicast.
E. Implement a purely deterministic routing scheme, disabling all adaptive routing features.

正解：C

解説：
A combination of AR and QOS provides the most flexible and effective solution. AR can dynamically adapt to changing traffic patterns and congestion, optimizing for large-message all-to-all communication. QOS can prioritize small-message parameter synchronization, minimizing latency for critical control traffic. Min Hop routing may not always choose the optimal paths, especially in complex topologies. Static routing is difficult to manage and doesn't adapt to changing network conditions. Disabling AR can lead to congestion.

質問 # 63
You're managing a cluster of servers with BlueField-2 DPUs. One server is experiencing intermittent network connectivity issues. You suspect a problem with the DPU's firmware. Which of the following is the MOST reliable method to determine the CURRENT firmware version of the BlueField-2 DPIJ?

A. Examine the '/proc/driver/mlx4_core/versiorf file.
B. Use the 'mst status' command to query the device status and firmware version.
C. Run 'ethtool -i on a network interface associated with the DPIJ.
D. Query the DPIJ's BMC (Baseboard Management Controller) via IPMI or Redfish.
E. Check the system logs for firmware-related messages during boot.

正解：B

解説：
'mst status' is the most reliable method. This command, part of the Mellanox OFED tools, is specifically designed to query the status of Mellanox devices, including the DPLJ, and accurately reports the firmware version. While other methods might provide clues, 'mst statuS is the definitive source of truth.
