NVIDIA AI Infrastructure Sample Questions (Q111-Q116):

NEW QUESTION # 111
Refer to the exhibit. Which type of NVIDIA LinkX cable has a teal color code?

A. Optical cables with passive circuitry (POCs)
B. Copper cables with active circuitry (ACCs)
C. Copper cables with direct attachment (DACs)
D. Optical cables with active circuitry (AOCs)

Answer: D

Explanation:
NVIDIA LinkX teal-colored cables indicate active optical cables. AOCs use optical fiber with active circuitry in the cable ends to support high-speed, longer-distance data center interconnects.

NEW QUESTION # 112
You are installing multiple NVIDIA GPUs in a server for a deep learning cluster. To optimally utilize the GPUs, which software component(s) are MANDATORY after the physical installation and driver setup? (Select TWO)

A. A web browser.
B. A text editor.
C. A spreadsheet program.
D. NVIDIA CUDA Toolkit.
E. A deep learning framework like TensorFlow or PyTorch.

Answer: D,E

Explanation:
The NVIDIA CUDA Toolkit provides the necessary libraries and tools for GPU-accelerated computing. A deep learning framework (TensorFlow or PyTorch) is required to build and train deep learning models that leverage the GPUs. While a web browser and text editor might be useful, they are not mandatory. Spreadsheet applications have no purpose here.

NEW QUESTION # 113
You are tasked with validating the cooling system for a high-density AI cluster using NVIDIA Blackwell GPUs, which generate up to 120 kW of power per rack. What should you prioritize during validation?

A. Validate that the cooling system can maintain a supply air temperature below 20°C at all times to ensure GPU stability.
B. Ensure that dynamic fan speed control is enabled to optimize airflow based on real-time thermal conditions.
C. Verify that each rack has sufficient airflow to handle 50% of its maximum heat load, as full load scenarios are rare.
D. Confirm that the cooling system uses liquid-to-air heat exchangers to manage heat dissipation efficiently.

Answer: D

Explanation:
Blackwell rack-scale systems can generate extremely high heat loads, so cooling validation must confirm that the facility cooling architecture can efficiently remove that heat at full rack density.
Liquid-to-air heat exchangers are designed to support high-density AI racks by transferring heat from liquid cooling loops into the facility air-cooling environment.

NEW QUESTION # 114
Consider a scenario where you're using GPUDirect Storage to enable direct memory access between GPUs and NVMe drives. You observe that while GPUDirect Storage is enabled, you're not seeing the expected performance gains. What are potential reasons and configurations you should check to ensure optimal GPUDirect Storage performance? Select all that apply.

A. Ensure that the NVMe drives are connected to the system via PCle Gen4 or Gen5.
B. Disable CPU-side caching to force all I/O operations to go directly to the GPU memory.
C. Check if the file system supports direct I/O (e.g., using 'directio' mount option).
D. Verify that the NVMe drives are properly configured in a RAID 0 configuration.
E. Confirm that the CUDA driver version is compatible with GPIJDirect Storage.

Answer: A,C,E

Explanation:
Explanation:GPUDirect Storage requires PCle Gen4/Gen5 for sufficient bandwidth (B). The CUDA driver must be compatible with GPUDirect Storage (C). Direct I/O support in the file system is essential to bypass the OS cache and allow direct GPU access (D). RAID 0 (A) is about storage speed but not directly related to GDS functionality. Disabling CPU-side caching (E) is usually detrimental as it can reduce overall system performance. Note, this is not always bad but needs to be tested depending on application.

NEW QUESTION # 115
You are running a Docker container with GPU support using 'nvidia-docker run'. The containerized application unexpectedly fails to detect the GPU. What is the most likely cause?

A. The Docker daemon is not configured to use the NVIDIA runtime.
B. The NVIDIA drivers are not installed on the host system.
C. The Docker image does not include the CUDA toolkit.
D. The application within the container is not linked against the CUDA libraries.
E. The =gpus all' flag was not specified when running the container.

Answer: E

Explanation:
When running containers that need GPU access, it's essential to explicitly request the GPU resources. The '-gpus all' or '-gpus device=..: flag passed to 'docker run' with the NVIDIA runtime allows the container access to the available GPUs. Without this flag, the container operates as if no GPUs are available. Options A, B, C and D, while potentially problematic, are not the most likely cause if 'nvidia-docker run' was used previously.
