NCP-AII Question 88
Select 3You are tasked with validating the hardware installation of an NVIDIA DGX system in a data center. Which of the following steps should you perform to confirm that the hardware has been correctly installed and is ready for use?
- A
Check that all GPUs are detected correctly using the
nvidia-smicommand. - B
Verify the system's cooling system is functioning by checking the GPU temperatures under load.
- C
Ensure the RAID configuration is optimized by running a synthetic disk performance test.
- D
Confirm all power supplies are operational by inspecting the system's management interface.
- E
Reinstall the operating system to ensure compatibility with the hardware.
Show answer and explanation
Correct answers: A, B, D
Explanation
Validating a hardware installation involves ensuring that all critical components, such as GPUs, cooling systems, and power supplies, are functioning as expected. The nvidia-smi command helps confirm GPU detection, system cooling can be validated by monitoring GPU temperatures, and the power supply status can be checked via the system management interface. Tasks like RAID optimization or OS reinstallation are either unrelated or unnecessary for this specific validation process.
- A. Correct.
Correct: The
nvidia-smicommand is an essential tool to verify that all GPUs are detected and functioning properly after installation. - B. Correct.
Correct: Checking the GPU temperatures under load helps confirm that the cooling system is working effectively and the hardware is not overheating.
- C. Incorrect.
Incorrect: While RAID configuration is important for storage, it is not directly relevant to validating the physical hardware installation of the DGX system.
- D. Correct.
Correct: Verifying the power supplies through the management interface ensures that the system has adequate and redundant power for stable operation.
- E. Incorrect.
Incorrect: Reinstalling the operating system is not a required step for validating hardware installation unless there are specific compatibility issues identified.
