A customer has 5,000 Android 10 devices in warehouses that are not connected to the internet. How can the customer get an OTA update to the device if they are only on a closed network?
(A) Since the devices are off the internet and safer, you do not need to keep the devices updated.
(B) Send the devices to the OEM for updating.
(C) Use only devices that are flashed with AOSP versions of Android so that you can get updates directly from the OEM.
(D) Use the manual update process combined with your EMM to push updates from a local server on the network.
