You have 20 IoT devices deployed across two floors of a building. The devices on the first floor must be set to 60 degrees. The devices on the second floor must be set to 80 degrees.
The device twins are configured to use a tag that identifies the floor on which the twins are located.
You create the following automatic configuration for the devices on the first floor.
You create the following automatic configuration for the devices on the second floor.
The IoT devices on the first floor report that the temperature is set to 80 degrees.
You need to ensure that the first-floor devices are set to the correct temperature.
Solution: In the automatic configuration for the second-floor devices, you set Version to 2.
Does this meet the goal?
A. Yes
B. No
You are developing an Azure IoT solution for a shipping company. The company's ships will have sensors used for predictive maintenance. Some sensor devices will be MQTT-capable, and others will use Modbus.
Each ship has an internet connection that is available only when the ship is docked.
You create an Azure IoT hub.
You need to implement an IoT solution that uses Azure IoT Edge.
What should you do?
A. Configure an IoT Edge gateway. Deploy an IoT Edge Modbus module. From the Azure portal, create IoT devices and add connection strings to the devices.
B. Add the MQTT devices to the IoT hub and configure an IoT Edge gateway. From the IoT Edge gateway device, assign the MQTT devices as child devices of the gateway. Use the File upload feature of IoT Hub when internet connectivity is available.
C. Add the MQTT devices to the IoT hub, configure an IoT Edge gateway, and set Enable connection to IoT Hub to Disable. From the IoT Edge gateway device, assign the MQTT devices as child devices of the gateway. Deploy the IoT Edge Modbus module.
D. Add the MQTT devices to the IoT hub and configure an IoT Edge gateway. From the IoT Edge gateway device, assign the MQTT devices as child devices of the gateway. Deploy an IoT Edge Modbus module.
You have an Azure IoT hub that has 1,000 registered devices.
You create an Azure logic app.
You need to send Device Connected and Device Disconnected events in real time to the logic app.
What should you do?
A. From the Message routing blade of the IoT hub, add a route, Route DeviceLifecycleEvents to an Azure Service Bus queue.
B. From the Diagnostic settings blade of the IoT hub, add a diagnostic setting. Route the connection logs to a Log Analytics workspace.
C. From the Events blade of the IoT hub, add an event subscription. Configure the Filter to Event Types setting and route the events to a webhook.
You have an Azure subscription that contains an Azure IoT hub and two Azure IoT Edge devices named Device1 and Device2.
You need to ensure that the IoT hub only accepts connections from Device1 and Device2.
What should you configure?
A. Azure API Management
B. Azure Active Directory (Azure AD) Identity Protection
C. Azure Defender for IoT
D. an IP filter
You have an Azure IoT solution that includes an Azure IoT hub named hub1.
You plan to deploy an Azure Time Series Insights Gen 2 environment and connect the environment to hub1.
You need to use the device ID from hub1 as the Time Series ID.
What should you set as the Time Series ID when creating the environment?
A. device-id
B. connection-device-id
C. iothub-connection-device-id
D. deviceId
You have an loT solution that includes an Azure IoT hub named Hub1 and 20 loT devices.
Hub1 sends cloud-to-device messages to the 10T devices.
You need to track the number of messages that are resubmitted for delivery to an IoT device. Which metric should you monitor?
A. C2D messages abandoned
B. C2D Messages Expired
C. C2D messages rejected
D. C2D message deliveries completed
HOTSPOT
You have an Azure subscription that contains an Azure IoT hub, an Azure IoT Edge gateway, and 1,000 leaf devices. The leaf devices use a custom communication protocol that is NOT supported by the IoT hub.
You need to configure the gateway to meet the following requirements:
Minimize the number of connections between the gateway and the IoT hub.
Support addressing cloud-to-device messages to individual leaf devices.
How should you configure the gateway? To answer, select the appropriate options in the answer area.
