You have an Azure IoT hub.
You plan to deploy 1,000 IoT devices by using automatic device management.
The device twin is shown below.
You need to configure automatic device management for the deployment.
Which target Condition and Device Twin Path should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Correct Answer:

Explanation:
Box 1: tags.engine.warpDriveType='VM105a'
Use tags to target twins. Before you create a configuration, you must specify which devices or modules you want to affect. Azure IoT Hub identifies devices and using tags in the device twin, and identifies modules using tags in the module twin.
Box 2: properties.desired.warpOperating
The twin path, which is the path to the JSON section within the twin desired properties that will be set.
For example, you could set the twin path to properties.desired.chiller-water and then provide the following JSON content:
{
"temperature": 66,
"pressure": 28
}

You have 100 devices that connect to an Azure IoT hub named Hub1. The devices connect by using a symmetric key.
You deploy an IoT hub named Hub2.
You need to migrate 10 devices from Hub1 to Hub2. The solution must ensure that the devices retain the existing symmetric key.
What should you do?

• A.Add a desired property to the device twin of Hub2. Update the endpoint of the 10 devices to use Hub2.
• B.Add a desired property to the device twin of Hub1. Recreate the device identity on Hub2.
• C.Recreate the device identity on Hub2. Update the endpoint of the 10 devices to use Hub2.
• D.Disable the 10 devices on Hub1. Update the endpoint of the 10 devices to use Hub2.
