NCP-AII Question 138
Select 2You 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 load the BlueField OS image onto the DPU. - B
Ensure that the DPU is in 'managed mode' before starting the deployment.
- C
Verify the compatibility of the OS image with the specific BlueField DPU model.
- D
Perform a secure boot reset on the DPU after deploying the OS image.
- E
Transfer the image to the Arm cores using the
scpcommand directly.
Show answer and explanation
Correct answers: A, C
Explanation
To successfully deploy the BlueField OS image to the Arm cores, you must use the bfb-install utility, which is designed for this purpose, and confirm the compatibility of the OS image with the specific DPU model. These steps ensure that the image is correctly deployed and operational. Other options listed either describe unnecessary steps or incorrect methods.
- A. Correct.
The
bfb-installutility is a standard tool provided by NVIDIA to deploy the BlueField OS image to the Arm cores. This is a required step for deployment. - B. Incorrect.
The DPU does not need to be in 'managed mode' for deploying the OS image. This is not a requirement for the deployment process.
- C. Correct.
It is critical to verify that the OS image is compatible with the specific BlueField DPU model to avoid deployment issues.
- D. Incorrect.
A secure boot reset is not typically required immediately after deploying the OS image. This step is unnecessary.
- E. Incorrect.
Using the
scpcommand directly to transfer the image is not the correct method for deploying the BlueField OS. Thebfb-installutility should be used instead.
