NVIDIA AI Infrastructure 認定 NCP-AII 試験問題 (Q48-Q53):

質問 # 48
You are deploying an NVIDIA GPU-accelerated application in a virtualized environment using vGPU. How does vGPU technology impact power and cooling considerations compared to a bare-metal deployment, and what specific monitoring metrics become crucial?

A. vGPU deployments can lead to higher overall power consumption and concentrated heat generation on the host server due to resource consolidation. Monitoring metrics like GPU utilization per VM, vGPU frame rate, and host server thermal headroom become crucial.
B. vGPU deployments eliminate the need for GPU monitoring, as the virtualization layer handles all power and cooling management.
C. vGPU deployments require specialized cooling solutions that are not needed for bare metal setups.
D. vGPU deployments have no significant impact on power and cooling requirements compared to bare-metal. Standard GPU temperature and power draw metrics are sufficient.
E. vGPU deployments typically require less power and cooling than bare-metal, as resources are shared. The host server's overall power consumption becomes the primary monitoring metric.

正解：A

解説：
vGPU deployments can increase overall power consumption and heat generation because multiple virtual machines share physical GPUs, concentrating the load on the host server. Monitoring GPU utilization per VM, vGPU frame rate, and host server thermal headroom becomes crucial to ensure optimal performance and prevent overheating. Host server thermal headroom refers to the difference between the maximum allowed temperature and the current operating temperature.

質問 # 49
A cluster administrator deploys GPUDirect RDMA for a distributed AI training environment. After deployment, GPU utilization improves while CPU utilization during communication decreases substantially. Which architectural change most directly explains this improvement?

A. PCIe transactions are replaced entirely by Ethernet broadcasts.
B. Data transfers bypass CPU memory and move directly between GPUs and network adapters.
C. All communication is redirected through NVSwitch.
D. Network traffic is compressed before entering GPU memory.

正解：B

解説：
GPUDirect RDMA allows compatible network adapters to access GPU memory directly, eliminating unnecessary copies through host memory and reducing CPU involvement. This lowers latency, decreases CPU overhead, and improves overall communication efficiency during distributed AI workloads. NVSwitch only affects intra-server communication, while GPUDirect RDMA operates across network fabrics.

質問 # 50
An enterprise IT team has completed the physical installation of an AI factory with a Spectrum-X Ethernet network connected to all GPU servers. They now need to ensure the environment is ready for scalable AI workload deployment. What is the recommended sequence of validation steps?

A. Perform application benchmarking, use performance logs to identify bottlenecks, update any switch and server firmware, tune the network using suitable performance tests.
B. Validate software stack, test link connectivity and port health, run network benchmarks, run OSPF, ensure neighbors are exchanging route info, then stage AI workload tests.
C. Confirm switch and server firmware configuration, test link connectivity and port health, run network benchmarks, validate software stack, then stage AI workload tests.
D. Set up Active Directory, LDAP, and configuring role-based access controls, and security configurations as the first task, install users, and validate network or hardware performance.

正解：C

解説：
After physical installation, the environment should be validated from the infrastructure layer upward. Confirming firmware and configuration first ensures supported component baselines, link and port checks verify physical connectivity, network benchmarks validate Spectrum-X fabric performance, software stack validation confirms the runtime environment, and staged AI workload tests confirm readiness for scalable production deployment.

質問 # 51
You've flashed the BlueField OS to your SmartNlC, but you need to customize the kernel command line arguments (bootargs) to enable a specific feature. Where is the MOST appropriate place to modify these arguments for persistent changes that survive reboots?

A. In the bootloader configuration file (e.g., extlinux.conf or grub.cfg) on the BlueFieId's flash memory.
B. Directly in the kernel image file itself using a hex editor.
C. In the '/proc/cmdline' file. This allows immediate changes.
D. Passing it as an argument to bfboot during deployment.
E. In the '/etc/default/grub' file on the BlueField OS, followed by updating the GRUB configuration.

正解：A

解説：
The bootloader configuration file (extlinux.conf, grub.cfg, uEnv.txt depending on the system) is where boot arguments are persistently stored. Modifying the kernel image directly is highly discouraged and risky. 'letc/default/grub' is a common location on standard Linux systems, but not necessarily on the BlueField OS's boot environment. '/proc/cmdline' shows the currently used arguments, but modifying it doesn't persist changes across reboots. bfboot will only change the image during that flash, changes at the bootloader level persist after subsequent flashes.

質問 # 52
In a data center utilizing NVIDIA GPUs and NVLink, what is the primary advantage of using a direct-attached NVLink network topology compared to routing traffic over the network?

A. Simplified network configuration
B. Reduced cost of network infrastructure
C. Increased network security
D. Improved power efficiency
E. Higher bandwidth and lower latency between GPUs

正解：E

解説：
Direct-attached NVLink provides significantly higher bandwidth and lower latency compared to routing traffic over a traditional network. This is crucial for applications that require intensive GPU-to-GPU communication, such as large-scale AI training. While direct-attached NVLink can simplify configuration in some cases, its primary advantage is the performance improvement.
