NVIDIA AI Infrastructure Sample Questions (Q136-Q141):

NEW QUESTION # 136
A cluster administrator is preparing to update the firmware on a DGX H100 system, including the GPU tray (baseboard). What is the correct sequence of steps to perform a safe and successful firmware upgrade?

Answer: C

Explanation:
Updating firmware on an NVIDIA DGX H100 is a multi-stage process that requires careful orchestration to prevent hardware corruption. The first and most critical step is to ensure no workloads are running (stopping all GPU activity) to avoid conflicts during the flashing process. The standard NVIDIA procedure begins with updating and rebooting theBaseboard Management Controller (BMC). This is because the BMC manages the power sequencing and communication for all other trays; having the latest management logic active is a prerequisite for the subsequent steps. Once the BMC is updated and back online, the administrator proceeds with the motherboard and GPU tray updates. However, these updates are staged in flash memory and often do not "take effect" until the hardware undergoes acold reset(removing power completely). This physical or logical power cycle forces the various CPLDs and silicon root-of-trust modules to boot from the newly written firmware images. Finally, the administrator must verify completion using tools like nvsm show health or the BMC dashboard to ensure all components report the target versions and a "Healthy" status. Skipping the BMC update first (Option C) or the cold reset (Option B) can lead to mismatched firmware states that may cause system instability or boot failures.


NEW QUESTION # 137
Which of the following steps are essential components of a recommended DGX cluster installation procedure? (Choose two.)

Answer: C,D

Explanation:
A recommended DGX cluster installation requires validating network interfaces and fabric connectivity before deploying cluster software so node provisioning and workload communication are reliable. Grouping nodes by function and assigning them to the proper cluster management categories ensures consistent configuration, management, and role-based deployment across the cluster.


NEW QUESTION # 138
An AI server utilizes a QSFP28 transceiver with MPO connector. During troubleshooting, you suspect a faulty transceiver. Which steps are most important to perform when physically inspecting and testing the transceiver?

Answer: E

Explanation:
The MOST important steps involve visual inspection for damage, cleaning the connector to ensure a good optical connection, and verifying DOM information to assess the transceivers health and signal levels. OTDR is more suited for cable diagnosis. While firmware and voltage are relevant, the DOM provides immediate health indicators.


NEW QUESTION # 139
A customer has just completed the first boot of their DGX system and is prompted to create an administrative user. What is the correct approach for setting up this user to ensure secure BMC and GRUB access?

Answer: C

Explanation:
During the initial "first boot" setup of an NVIDIA DGX system (such as the DGX H100 or A100), the installation wizard requires the creation of a primary administrative user. This account is pivotal because it is used not only for local OS login but is also synchronized to provide access to the Baseboard Management Controller (BMC) and the GRUB bootloader. NVIDIA best practices emphasize security by mandating the use of a unique, strong password. Using a lower-case username is a standard Linux convention that ensures compatibility across various authentication services. By setting this up correctly during the first boot, the system ensures that "out-of-band" management (via BMC) and "pre-boot" configuration (via GRUB) are protected from unauthorized access. Relying on default credentials (Option B) or weak passwords (Option D) is a significant security risk in AI infrastructure, as the BMC often has high-level control over power, firmware, and remote console access.


NEW QUESTION # 140
You are working with a BlueField-3 DPIJ and wish to programmatically control the PCle link speed and width. Which interface exposes the most direct way to manage these low-level hardware settings on the DPU?

Answer: B

Explanation:
The 'mlxconfig' utility (or its equivalent for newer BlueField generations) is specifically designed for configuring Mellanox/NVlDlA network adapters, including BlueField DPUs. It provides access to a wide range of hardware settings, including PCle link speed and width. NVML is primarily for GPU management, not DPIJ configuration. 'ethtoor manages network interface settings, but not PCle link parameters. Accessing the PCle configuration space directly is possible but complex and risky. Modifying the DTB is a more permanent and low-level approach, typically used during initial board configuration, not for runtime adjustments.


NEW QUESTION # 141
......

Most of the candidates who plan to take the NCP-AII certification exam lack updated practice questions to ace it on the first attempt. Due to this, they fail the NVIDIA AI Infrastructure (NCP-AII) test, losing money and time. And in some cases, applicants fail on the second attempt as well because they don't prepare with NCP-AII Actual Exam questions. This results in not only the loss of resources but also the motivation of the candidate.
