NVIDIA AI Infrastructure Sample Questions (Q192-Q197):

NEW QUESTION # 192
You are leading a project to enhance the energy efficiency of a data center that heavily relies on AI workloads. NVIDIA suggests moving beyond traditional metrics like Power Usage Effectiveness (PUE) to better capture the efficiency of modern data centers. Which strategy should you prioritize to develop more accurate energy-efficiency metrics?

A. Develop benchmarks tailored to specific workloads, such as MLPerf for AI applications, to better understand energy use in real-world scenarios.
B. Use watts-used as the primary measure of efficiency, as it accurately reflects the power input at any given time.
C. Use Power Usage Effectiveness as the primary metric while supplementing it with additional measures of useful work done per unit of energy.
D. Focus on integrating kilowatt-hours into existing metrics to better reflect the actual energy used for productive work.

Answer: A

Explanation:
The best strategy is to use workload-specific benchmarks such as MLPerf-style AI benchmarks to understand energy efficiency in real-world scenarios. NVIDIA has argued that traditional PUE is not enough for modern AI data centers because PUE measures facility overhead relative to IT power, but it does not measure useful computational output. For AI infrastructure, the important question is not only how much power the facility consumes, but how much useful AI work is completed per unit of energy. NVIDIA's discussion of next- generation efficiency metrics emphasizes useful work per energy and the need to account for real applications.
Kilowatt-hours are useful for measuring energy consumed, but they do not by themselves capture productive AI output. Watts-used is only instantaneous power and does not reflect completed work. PUE remains useful for facilities management, but relying on it as the primary metric misses the performance and efficiency characteristics of accelerated computing. Workload-specific benchmarks allow teams to compare training, inference, and system performance against energy consumed in practical AI operations.

NEW QUESTION # 193
An engineer is reimaging a DGX system in a large cluster. Which method ensures the most efficient and secure remote installation without physical access?

A. Use apt-get to upgrade the operating system without rebooting the system.
B. Skip ISO verification and directly flash the operating system to the disk via SSH.
C. Build a software image on Base Command Manager and then reimage the system.
D. Create a USB drive with the ISO and manually boot from it on the DGX system.

Answer: C

Explanation:
Building a software image in NVIDIA Base Command Manager and using it to reimage the DGX system is the most efficient and secure method in a large cluster. In managed DGX infrastructure, remote image provisioning allows administrators to maintain consistent operating system versions, drivers, CUDA components, network settings, security baselines, and cluster management agents across compute nodes. This avoids manual access to each server and reduces configuration drift. Using apt-get to upgrade the operating system is not equivalent to a controlled reimage and may leave inconsistent packages or unsupported driver combinations. Creating a USB drive requires physical access and does not scale for large deployments.
Skipping ISO verification and directly flashing the operating system over SSH is unsafe because it bypasses image validation and can leave nodes in an unrecoverable or untrusted state. BCM-based imaging supports repeatable deployment, centralized control, rollback planning, and integration with node categories or software images. This is the preferred operational model for reliable DGX cluster bring-up and lifecycle management.

NEW QUESTION # 194
A system administrator needs to install a container toolkit and successfully run the following commands:

What step should be taken next to finish the installation?

A. systemctl restart docker
B. dpkg -i doca-host-repo-ubuntu<version>_am64.deb</version>
C. apt-get install cuda-drivers
D. apt-get remove nvidia-container-toolkit for

Answer: A

Explanation:
After configuring the NVIDIA Container Toolkit runtime for Docker with nvidia-ctk runtime configure --runtime=docker, Docker must be restarted so it reloads the updated runtime configuration and can run GPU-enabled containers correctly.

NEW QUESTION # 195
Consider the following Dockerfile snippet:

This Dockerfile is used to build a deep learning application. After building and running a container from this image, you observe that the application is not detecting the GPU. You have verified that the NVIDIA Container Toolkit is installed and configured correctly on the host. What is the most likely reason for this issue?

A. The 'requirements.txt' file is missing the 'nvidia-pyindex' package.
B. The application code in 'app.py' is not explicitly requesting GPU resources.
C. The base image 'nvidia/cuda:ll .6.2-base-ubuntu20.04' does not include the necessary NVIDIA Container Toolkit components.
D. The 'docker run' command is missing the '-gpus all' flag.
E. The CUDA version on the host is different than the one specified in the Dockerfile.

Answer: D

Explanation:
The 'docker run' command must include the =gpus all' (or equivalent) flag to explicitly request GPU resources for the container (C). The base image 'nvidia/cuda:ll .6.2-base-ubuntu20.04' provides the CUDA runtime, but the NVIDIA Container Toolkit on the host handles the GPU device mapping. The application code (B) doesn't need to explicitly request GPUs; the CUDA runtime will handle that. 'nvidia-pyindex' (D) is related to package management, not GPU detection. The Dockerfile includes a specific CUDA version that mitigates version differences (E). The base image does not include the Container Toolkit, which is installed on the HOST.

NEW QUESTION # 196
An engineer is tasked with configuring Out-of-Band (OOB) management for a DGX BasePOD deployment. Which network design will best ensure secure and reliable OOB management operations?

A. Place all BMC and management interfaces on an isolated OOB network with access restricted by firewall rules.
B. Configure OOB management interfaces to be accessible from any subnet within the data center for maximum flexibility.
C. Use a single VLAN for both OOB management and compute fabric to simplify network design.
D. Connect OOB management ports to the same switch as user traffic for easier troubleshooting.

Answer: A

Explanation:
OOB management should be isolated from production and compute traffic because BMC interfaces provide privileged hardware-level access. Placing BMC and management interfaces on a dedicated OOB network with firewall-restricted access improves security, reliability, and operational control for DGX BasePOD management.
