You need to connect 100 distributed sensors to your Azure IoT infrastructure. Most of the devices are Azure certified smart sensors developed by a major manufacturer but there are several devices developed in-house, by your engineering department. You want to use the bulk provisioning process supported by IoT Central. 
Which of the following steps cannot be skipped for your in-house devices?

Answer options:

A.Export device data to CSV
B.Create a device template
C.Configure device capabilities
D.Import list of devices from CSV

Answer: C
Option A is incorrect because during bulk provisioning, the device list, together with the credentials can be exported to CSV, which then can be used to update the code of the devices. (This step must be preceded by the “Import list of devices from CSV” step.)
Option B is incorrect because when creating “standard” devices, selecting a device template is required. For certified equipment, it is created automatically.
Option C is CORRECT because Azure certified device templates come fully pre-configured and they are ready to use. For your own devices, however, the capabilities (as well as other properties of the device template) must be manually defined and configured.
Option D is incorrectduring bulk provisioning of devices, the list of device ID-s and names can be imported from CSV. IoT Central then automatically generates the devices with the necessary SAS keys. Imported devices are created as “Unassigned”, i.e. not having a template associated.
