Correct Answer: A, BTo update the SSD firmware in a Nutanix cluster without Internet access, you would need to download the necessary updates beforehand and make them accessible within the internal network. First, you would download a darksite bundle that contains the firmware updates and deploy it on an internal webserver so the cluster can reach the necessary files internally. Then, you would proceed with the firmware update process by selecting the option to Upgrade Software within the Nutanix management interface and uploading the firmware bundle you have prepared. This process ensures the firmware is correctly applied without requiring direct Internet access.
