NCP-AII Question 86
Select 4You are tasked with validating the hardware installation of an NVIDIA DGX system in your data center. After the physical installation, which of the following steps should you perform to ensure the hardware is properly installed and operational?
- A
Verify that the system's power cables are securely connected and the system powers on without errors.
- B
Check the GPU temperatures in the system's monitoring tools to ensure they are within normal operating ranges.
- C
Run a diagnostic tool, such as NVIDIA System Management Interface (nvidia-smi), to confirm GPU availability and functionality.
- D
Manually inspect the internal wiring of the system to ensure no cables are touching the GPUs.
- E
Ensure that the operating system has the latest NVIDIA driver installed and recognizes the installed GPUs.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
Validating hardware installation involves multiple steps to ensure the system is functional and ready for use. These steps include verifying power and boot functionality, checking GPU temperatures to confirm normal operation, using diagnostic tools to ensure GPU availability, and ensuring the correct drivers are installed. While inspecting internal wiring may help in certain troubleshooting scenarios, it is not a standard part of the validation process unless there is an indication of a specific problem.
- A. Correct.
Verifying the power cables and the system's ability to boot without errors is a critical step in hardware validation to ensure the system is properly installed and operational.
- B. Correct.
Monitoring GPU temperatures helps confirm that the hardware is functioning as expected and that there are no thermal issues after installation.
- C. Correct.
Running a diagnostic tool like nvidia-smi ensures that the GPUs are detected and operating correctly, which is essential for validating hardware functionality.
- D. Incorrect.
While inspecting the internal wiring may seem important, it is not a standard part of the hardware validation process unless there is a specific issue suspected. Proper cable management should have already been addressed during installation.
- E. Correct.
Ensuring the operating system has the latest NVIDIA driver and recognizing the GPUs is a key step in validating that the hardware is correctly installed and ready for use in AI workloads.
