I think it should be - Obtain cred - Generate cred - Flash cred - Connect - Associate We need to obtain the IoT Central application's group primary key first to generate the device credentials. https://docs.microsoft.com/en-us/azure/iot-central/core/concepts-get-connected#connect-without-registering-devices

theiotguy is right. The question is not well written. The first step should be written as "Obtain the group primary key from the IoT Central enrollment group". The second step should be "User the group primary key to generate device credentials" Purposely obtuse in order to confuse. Poor question.

To make sense, "obtain the credential" should be moved to step 3
