Câu 15: NCP-AII: NCP-AI Infrastructure

As the infrastructure lead for an NVIDIA AI Factory deployment, you have just uploaded the latest supported firmware packages to your DGX system. It is now critical to ensure all hardware components run the new firmware and the DGX returns to full operational capability. Which sequence best guarantees that all relevant components are correctly running updated firmware according to NVIDIA’s documentation and recommended operational steps?

1. A. Execute a single AC power cycle on the DGX after the update process, then reset the software stack and verify status using diagnostic commands on each node for confirmation of all component updates.
2. B. Initiate a cold power cycle on the system to activate firmware for components, reset the BMC using the recommended command, and perform an AC power cycle to ensure EROT and CPLD firmware is activated. — đáp án hiện tại
3. C. Perform a software-driven restart on the operating system of every compute node, then use advanced tools to check firmware status, and reissue update commands if any firmware appears inactive afterward.
4. D. Initiate a cold power cycle on all node trays to activate firmware, follow with a DGX reboot procedure, and use the management interface to finish activating CPLD firmware on the host.
