Device pools define sets of “common characteristics for devices” – this writes off other answers
A is the answer
Device pools define sets of common characteristics for devices. The device pool structure supports the separation of user and location information. The device pool contains system, device, and location-related information. The Common Device Configuration window under Device > Device Settings > Common Device Configuration records all the user-oriented information such as type of softkey template that is used and locale information. Ensure that each device is associated with a device pool and with a common device configuration for user-oriented information.
