You have an Azure IoT Central application.
You add an IoT device named Oven1 to the application. Oven1 uses an IoT Central template for industrial ovens.
You need to send an email to the managers group at your company as soon as the oven temperature falls below
400 degrees.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

• A.Create a SendGrid account in the same resource group as the IoT Central application.
• B.Add a condition that has Time Aggregation set to Off.
• C.Add a condition that has Aggregation set to Minimum.
• D.Add the Manager role to the IoT Central application.
• E.From IoT Central, create a telemetry rule for the template.

Correct Answer: B,E

Explanation
Devices use telemetry to send numerical data from the device. A rule triggers when the selected telemetry crosses a specified threshold.
E: To create a telemetry rule, the device template must include at least one telemetry value. The rule monitors the temperature reported by the device and sends an email when it falls below 400 degrees.
B: Configure the rule conditions.
Conditions define the criteria that the rule monitors. In this tutorial, you configure the rule to fire when the temperature exceeds 70° F.
1. Select Temperature in the Telemetry dropdown.
2. Next, choose Is less than as the Operator and enter 400 as the Value.

3. Optionally, you can set a Time aggregation. When you select a time aggregation, you must also select an aggregation type, such as average or sum from the aggregation drop-down.
* Without aggregation, the rule triggers for each telemetry data point that meets the condition.
* With aggregation, the rule triggers if the aggregate value of the telemetry data points in the time window meets the condition.

You have an Azure IoT solution that includes an Azure IoT hub and 100 Azure IoT Edge devices.
You plan to deploy the IoT Edge devices to external networks. The firewalls of the external networks only allow traffic on port 80 and port 443.
You need to ensure that the devices can connect to the IoT hub. The solution must minimize costs.
What should you do?

• A.Configure the upstream protocol of the devices to use MQTT over TCP.
• B.Configure the upstream protocol of the devices to use AMQP over WebSocket.
• C.Connect the external networks to the loT solution by using ExpressRoute.
• D.Integrate cellular communication hardware onto the devices and avoid the use of the external networks.
