質問 # 38
A DGX H100 system shows intermittent "Link Down" errors on a 200G DAC cable. CVT reports "No Signal" despite physical connection. What is the first hardware check?
正解：C
解説：
The first hardware check should be cable compatibility and connector inspection. A "No Signal" result from the Cable Validation Tool indicates that the physical layer is not establishing a usable signal, even though the cable appears to be inserted. In DGX H100 and NVIDIA high-speed networking environments, DAC cables must be validated for the correct speed, adapter generation, switch platform, firmware compatibility, and physical form factor. A damaged connector, unsupported cable, poorly seated latch, excessive bend radius, or wrong cable type can cause intermittent "Link Down" events. Replacing an optical transceiver is not appropriate because the issue is on a DAC connection, not an optical link. Reconfiguring the port to 100G may mask the failure but does not validate the required 200G operation. Upgrading all switches for RS-FEC is too broad and does not address a local "No Signal" condition. Proper physical-layer bring-up requires confirming the cable is supported, visually inspecting both ends, reseating it, and checking whether the link comes up cleanly before moving to firmware or switch-level troubleshooting.
質問 # 39
You are managing a cluster of servers with NVIDIA GPUs. You want to automate the process of installing and updating NVIDIA drivers across all nodes. Which of the following approaches would be the most scalable and maintainable?
正解：A、E
解説：
Configuration management tools (Ansible, Chef, Puppet) provide the most scalable and maintainable solution. They allow you to define the desired state of the system and automatically enforce it across all nodes. NVIDIA's container toolkit encapsulates the driver and provides a consistent, isolated environment. Manually SSHing is not scalable. While 'pdsh' and 'parallel' can automate the execution of commands, they lack the robust error handling and state management of configuration management tools. NFS distribution requires managing the installation process separately on each server.
質問 # 40
Your AI training workload involves a large dataset stored in an object storage system (like AWS S3). You notice that fetching data directly from S3 during training is a bottleneck. Which of the following strategies can significantly improve data loading performance?
正解：B
解説：
A caching layer brings frequently accessed data closer to the compute nodes, reducing latency and improving throughput. Increasing retries only addresses transient errors. Reducing data loaders worsens performance. Switching providers might not solve the underlying latency issue. S3 Glacier is for archival, so will result in worse performance.
質問 # 41
You are a network administrator responsible for configuring an East-West (E/W) Spectrum-X fabric using SuperNIC. The Bluefield-3 devices in your network should be set to NIC mode with RoCE enabled to optimize data flow between servers. You have access to the Spectrum-X management tools and the necessary documentation. You need to use specific configuration commands to achieve this setup. Which of the following steps and commands are necessary to configure the Bluefield-3 devices in NIC mode for the E/W Spectrum-X fabric using SuperNIC? (Pick the 2 correct responses below)
正解：A、D
解説：
NVIDIA Spectrum-X is the world's first high-performance Ethernet fabric designed specifically for AI, combining Spectrum-4 switches with BlueField-3 SuperNICs. To achieve the high-throughput, low-latency requirements of East-West (server-to-server) AI traffic, the BlueField-3 hardware must be correctly provisioned. The first requirement is ensuring the physical ports are operating in Ethernet mode; LINK_TYPE_P1=2 (and P2=2 for the second port) toggles the hardware from InfiniBand to Ethernet mode.
Secondly, the BlueField-3 can operate in several "modes." While "DPU mode" (Option D) offloads the entire OS to the ARM cores, "NIC mode" (or SuperNIC mode) allows the host to manage the networking while leveraging theInternal CPU Offload Engine. Setting INTERNAL_CPU_OFFLOAD_ENGINE=1 is a specific configuration step for Spectrum-X that allows the SuperNIC to handle RoCE (RDMA over Converged Ethernet) and Congestion Control (CC) algorithms more efficiently at 400G speeds. This setup is vital for AI workloads like LLM training, where consistent latency and zero-packet-loss are non-negotiable for collective communications.
質問 # 42
You're deploying a BlueField-2 DPU in a cloud environment and need to ensure the integrity of the DPU's firmware. You want to verify that the firmware hasn't been tampered with. Which of the following methods provides the strongest level of assurance for firmware integrity?
正解：A
解説：
Digitally signed firmware provides the strongest guarantee of integrity. The signature verifies that the firmware hasn't been tampered with since it was signed by NVIDIA. SHA256 checksums are good, but digital signatures are cryptographically stronger. MD5 checksums are considered weak and easily compromised. Firmware version and file size offer minimal assurance against sophisticated attacks.
