Question # 1

You are planning a proof of concept (POC) that will use an Azure IoT hub. You have two self-signed client authentication certificates named Cert1 and Cert2. Cert1 has a basic constraint that contains Subject Type=CA. Cert2 has a basic constraint that contains Subject Type=End Entity.

You need to identify which certificates to use. What should you identify? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Hot Area:


Box 1: Cert2 only Cert2: The leaf certificate, or end-entity certificate, identifies the certificate holder. It has the root certificate in its certificate chain as well as zero or more intermediate certificates. The leaf certificate is not used to sign any other certificates. It uniquely identifies the device to the provisioning service and is sometimes referred to as the device certificate.

Box 2: Cert1 only Cert1: A root certificate is a self-signed X.509 certificate representing a certificate authority (CA). It is the terminus, or trust anchor, of the certificate chain. Root certificates can be self-issued by an organization or purchased from a root certificate authority.



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.

Answer: BE

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.



Your company is creating a new camera security system that will use Azure IoT Hub.
You plan to use an Azure IoT Edge device that will run Ubuntu Server 18.04.
You need to configure the IoT Edge device.

Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
