最新的 NVIDIA-Certified Professional NCP-AII 免費考試真題 (Q70-Q75):

問題 #70
You want to limit the GPU memory available to a specific Docker container running a deep learning model. Which of the following 'docker run' commands using the NVIDIA Container Toolkit is the most appropriate?

答案：A

解題說明：
The correct syntax to limit GPU memory for a Docker container using the NVIDIA Container Toolkit involves specifying the GPU device using its UUID and then setting the memory limit. 'docker run --gpus '"device=GPU-UUlD:memory=4g"' my-image' is the correct way to achieve this. The others are syntactically incorrect or do not utilize the intended functionality. You need to find the GPU UUID using 'nvidia-smi' and replace 'GPIJ-IJIJID' with it.


問題 #71
You are tasked with ensuring optimal power efficiency for a GPU server running machine learning workloads. You want to dynamically adjust the GPU's power consumption based on its utilization. Which of the following methods is the MOST suitable for achieving this, assuming the server's BIOS and the NVIDIA drivers support it?

答案：A

解題說明：
DCGM provides the most comprehensive and automated solution for dynamic power management. It can monitor GPIJ utilization in real-time and adjust the power limit based on predefined policies, ensuring optimal power efficiency without manual intervention. Manually adjusting the power limit is possible but requires scripting and continuous monitoring. Dynamic Boost is typically for laptops, and BIOS power profiles may not be fine-grained enough. Disabling ECC reduces power but compromises data integrity.


問題 #72
You are troubleshooting performance issues in an A1 training clusten You suspect network congestion. Which of the following network monitoring tools would be MOST helpful in identifying the source of the congestion?

答案：B,D

解題說明：
iPerf/Netperf can measure network bandwidth and latency between nodes, allowing you to quantify congestion. tcpdump/Wireshark can capture and analyze network packets, providing detailed insights into traffic patterns and potential bottlenecks. Ping and Traceroute are useful for basic connectivity testing but not for detailed congestion analysis. netstat shows network statistics but doesn't capture packet-level details.


問題 #73
You have installed NVIDIA drivers using the .run' installer on a system running Ubuntu. However, after each kernel update, the NVIDIA drivers stop working. What is the most effective way to address this issue permanently?

答案：D

解題說明：
DKMS (Dynamic Kernel Module Support) is the most effective solution. It automatically rebuilds kernel modules (like NVIDIA's) whenever a new kernel is installed. Re-running the Irun' installer is a manual and error-prone process. Disabling kernel updates is not recommended for security reasons. Manually compiling is complex and time-consuming. Symlinking old modules is unlikely to work due to kernel API changes.


問題 #74
An A1 server is exhibiting unusually high CPU utilization during a GPU-accelerated workload. How can you determine if the CPU is becoming a bottleneck, preventing the GPUs from achieving their full potential?

答案：B

解題說明：
All the options provide valid methods for identifying a CPU bottleneck. Monitoring CPU and GPU utilization, profiling the application, and running parallel benchmarks all help to determine if the CPU is limiting GPU performance.


問題 #75
......
