NCP-AII Question 137
Single answerYou are tasked with deploying the BlueField OS image to the Arm cores of an NVIDIA BlueField DPU. Which step is essential to ensure a successful deployment?
- A
Ensure the DPU is in Network Boot mode before starting the deployment process.
- B
Use the
ddcommand to directly copy the BlueField OS image to the x86 host's storage. - C
Verify that the Arm subsystem is in reset state before deploying the image.
- D
Use the NVIDIA BlueField CLI command
bfb-installto install the image on the Arm cores.
Show answer and explanation
Correct answer: D
Explanation
The bfb-install command is specifically designed to facilitate the deployment of BlueField OS images to the Arm subsystem of the DPU. This command ensures proper installation and prepares the Arm cores for operation. While other options may touch on related concepts, they do not directly address the deployment of the BlueField OS image to the Arm cores.
- A. Incorrect.
While Network Boot mode is an option for booting the DPU, it is not a required step for deploying the BlueField OS image. The deployment process typically involves image installation using specific tools.
- B. Incorrect.
The
ddcommand is not used for deploying the BlueField OS image to the Arm cores. This command is primarily for low-level disk copying and does not interact with the Arm subsystem of the DPU. - C. Incorrect.
Although ensuring the Arm subsystem is in the correct state is important, placing it in a reset state is not a requirement for deploying the BlueField OS image.
- D. Correct.
The
bfb-installcommand is the correct and recommended way to deploy the BlueField OS image to the Arm cores of the NVIDIA BlueField DPU.
