What is the method for setting up an HPE Aruba Networking CX 8100 switch using...

The correct answer is B. Connect the USB Bluetooth adapter to the switch’s USB-A port. HPE Aruba Networking CX 8100 installation documentation states that the Aruba CX mobile app and Aruba USB Bluetooth adapter enable switch configuration from a mobile device. It also identifies the CX 8100 front-panel USB-A auxiliary port as the port used for file management, switch software downloads, or Aruba accessories. Therefore, for an Android mobile setup workflow using the Aruba CX mobile app, the USB Bluetooth adapter connects to the switch’s USB-A auxiliary port. The USB-C port on the CX 8100 is a serial console port, not the port for the USB Bluetooth adapter. Connecting the Android phone directly to the USB-C console port is not the Bluetooth mobile-app method. Connecting the phone to the management port with an RJ-45 adapter is also not the recommended mobile-app setup method. The supported mobile method is the Aruba CX mobile app through the USB Bluetooth adapter.
