NCP-AII Question 136
Select 2You are tasked with deploying the BlueField OS image to the Arm cores of an NVIDIA BlueField DPU in a data center environment. Which of the following steps are necessary to complete this task correctly?
- A
Transfer the BlueField OS image to the host system using a secure SCP or HTTP method.
- B
Use the
bfb-installcommand on the BlueField DPU to install the OS image. - C
Ensure the DPU is in 'Arm Trusted Boot Mode' before deployment to maintain security.
- D
Run the
bfctlutility from the host system to manage and monitor the deployment process. - E
Reboot the BlueField DPU after installation to apply the new OS image.
Show answer and explanation
Correct answers: B, E
Explanation
Deploying the BlueField OS image to the Arm cores of an NVIDIA BlueField DPU requires using the bfb-install command to install the OS image and rebooting the DPU to apply the changes. While other utilities like bfctl can manage the DPU, they are not part of the specific OS deployment process. Understanding the required tools and steps ensures successful deployment in an enterprise AI infrastructure.
- A. Incorrect.
Transferring the image to the host system is not necessary. The BlueField OS image deployment process directly involves the DPU itself, not just the host system.
- B. Correct.
The
bfb-installcommand is the correct tool used on the BlueField DPU to install the OS image onto the Arm cores. - C. Incorrect.
While security configurations are important, 'Arm Trusted Boot Mode' is not a required step for deploying a BlueField OS image.
- D. Incorrect.
The
bfctlutility is used for querying and managing BlueField devices but is not directly involved in the deployment of the OS image. - E. Correct.
Rebooting the BlueField DPU is a necessary step to apply the newly installed OS image and ensure it runs properly.
