NCP-AII Question 89
Select 4You are tasked with validating the hardware installation of an NVIDIA DGX system in a data center. During the validation process, which of the following steps should you perform to ensure that the system hardware is properly installed and functioning as expected?
- A
Check that all power supplies are connected and their status LEDs indicate proper operation.
- B
Ensure the GPUs are detected and functioning by running the NVIDIA System Management Interface (nvidia-smi) command.
- C
Verify that the data center's cooling system maintains a temperature below 10°C to prevent hardware overheating.
- D
Confirm that the network interface cards (NICs) are properly connected and operational by testing network connectivity.
- E
Inspect the BIOS settings to ensure they are configured for optimal performance with the installed hardware.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
Validating hardware installation for an NVIDIA DGX system involves ensuring that all components are properly connected, detected, and configured for optimal operation. This includes checking power supplies, verifying GPU detection, testing network connectivity, and inspecting BIOS settings. Proper cooling is also important, but the temperature mentioned in one of the options is not realistic or recommended for standard data center operations.
- A. Correct.
Checking power supplies and their status LEDs ensures that the system is receiving adequate and stable power, which is critical for operation.
- B. Correct.
Running the nvidia-smi command helps verify that all GPUs are detected and functioning as expected, which is necessary for AI workloads.
- C. Incorrect.
Maintaining a temperature below 10°C is not a realistic or recommended data center operating condition. The optimal range is typically between 18°C and 27°C.
- D. Correct.
Testing network connectivity confirms that the NICs are properly installed and operational, ensuring the system can communicate over the network.
- E. Correct.
Inspecting and configuring BIOS settings ensures that the system is optimized for high-performance workloads, including AI infrastructure.
