NCP-AII Question 140
Select 3You are tasked with deploying the BlueField OS image to the Arm cores of an NVIDIA BlueField Data Processing Unit (DPU). Which of the following steps are required to ensure a successful deployment?
- A
Use the
bfb-installutility to write the BlueField OS image to the DPU. - B
Ensure that the DPU is in Reset mode before beginning the deployment process.
- C
Transfer the BlueField OS image to the management host connected to the DPU.
- D
Verify that the image checksum matches the provided reference checksum before deployment.
- E
Use the
nvsmtool to install the OS image directly onto the Arm cores of the DPU.
Show answer and explanation
Correct answers: A, C, D
Explanation
Deploying the BlueField OS image to the Arm cores of an NVIDIA BlueField DPU requires using the bfb-install utility, transferring the image to the management host, and verifying the integrity of the image via a checksum match. These steps ensure the deployment is reliable and secure. Other actions, such as putting the DPU in Reset mode or using the nvsm tool, are either unnecessary or incorrect for this specific task.
- A. Correct.
Correct: The
bfb-installutility is specifically designed to write the BlueField OS image to the DPU, making it a required step for deployment. - B. Incorrect.
Incorrect: The DPU does not need to be in Reset mode for this process. Resetting the DPU is typically for troubleshooting or reinitialization purposes, not a mandatory step for deployment.
- C. Correct.
Correct: The BlueField OS image must be transferred to the management host connected to the DPU before it can be deployed.
- D. Correct.
Correct: Verifying the image checksum ensures the integrity of the OS image and is a critical step to prevent deployment of corrupted files.
- E. Incorrect.
Incorrect: The
nvsmtool is used for managing NVIDIA GPUs and systems but is not utilized for deploying the BlueField OS image to the DPU.
