You are building a solution with several pressure sensors connected to an edge device. Because of the large amount of incoming data, you decide to deploy a Stream Analytics job to the edge device, which can also reset the sensor device in case of errors. Telemetry data from PressureSensor must be sent to IoT Hub and to the Stream Analytics job. The alert messages must go to the IoT Hub and to the PressureSensor module to force a reset command on the device.

Which of the following parameters goes to Script1?

Answer options:

A.FROM /messages/modules/PressureSensor/* INTO $upstream
B.FROM /messages/modules/{myAsaModule}/* INTO $upstream
C.FROM /messages/modules/{myAsaModule}/* INTO BrokeredEndpoint("/modules/PressureSensor/inputs/control")
D.FROM $downstream INTO /messages/modules/PressureSensor/*

Correct Answer: A 
Diagram: 

Option A is CORRECT because this route defines the path for sending sensor telemetry data to the $upstream, which is the IoT Hub, actually.
Option B is incorrect because it defines the path for sending pre-processed data from the Stream Analytics module to the cloud.
Option C is incorrect because this route can be used to send messages from the Stream Analytics job back to the PressureSensor.
Option D is incorrect because there is no $downstream parameter (you should use /messages/modules/{moduleName}), hence the statement is invalid.
