AZ-220 Exam Dumps - Microsoft Azure IoT Developer
You have 1,000 IoT devices that connect to an Azure IoT hub.
Each device has a property tag named city that is used to store the location of the device.
You need to update the properties on all the devices located at an office in the city of Seattle as quickly as possible. Any new devices in the Seattle office that are added to the IoT hub must receive the updated properties also.
What should you do?
You are building an Azure loT solution that will include an Azure loT hub and will process environmental data for a multi-story building by using Azure Stream Analytics. The loT devices for the solution will provide the following data:
• Temperature
• Building
• Room
• Floor
You need to identify which data formats the loT devices can use to send the data as an array. What should you identify?
You have an Azure IoT hub that is being taken from prototype to production.
You plan to connect IoT devices to the IoT hub. The devices have hardware security modules (HSMs). You need to use the most secure authentication method between the devices and the IoT hub. Company
policy prohibits the use of internally generated certificates.
Which authentication method should you use?
You have an Azure subscription named Sub1.
You need to ensure that when a new Azure loT hub is created in Sub1, a warning appears indicating that communication must be allowed only from known networks. The solution must minimize development and administrative effort.
What should you include in the solution?
You have an Azure IoT solution that includes a standard tier Azure IoT hub and an IoT device.
The device sends one 100-KB device-to-cloud message every hour.
You need to calculate the total daily message consumption of the device. What is the total daily message consumption of the device?
You have an Azure Stream Analytics job that connects to an Azure IoT hub named Hub1445 as a streaming data source. Hub1445 is configured as shown in the exhibit. (Click the Exhibit tab.)
The Stream Analytics job fails to receive any messages from the IoT hub. What should you do to resolve the issue?
You have an Azure IoT hub that uses a Device Provisioning Service instance.
You have 1,000 legacy IoT devices that only support MAC address or serial number identities. The device do NOT have a security feature that can be used to securely identify the device or a hardware security module (HSM).
You plan to deploy the devices to a secure environment.
You need to configure the Device Provisioning Service instance to ensure that all the devices are identified securely before they receive updates.
Which attestation mechanism should you choose?
You need to enable telemetry message tracing through the entire IoT solution.
What should you do?
You plan to deploy Azure Time Series Insights.
What should you create on iothub1 before you deploy Time Series Insights?
You have an existing Azure IoT hub.
You use IoT Hub jobs to schedule long running tasks on connected devices.
Which two operations do the IoT Hub jobs support directly? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
You need to store the real-time alerts generated by Stream Analytics to meet the technical requirements.
Which type of Stream Analytics output should you configure?
How should you complete the GROUP BY clause to meet the Streaming Analytics requirements?
You need to add Time Series Insights to the solution to meet the pilot requirements.
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.
You need to configure Stream Analytics to meet the POV requirements.
What are two ways to achieve the goal? Each Answer presents a complete solution.
NOTE: Each correct selection is worth one point.
During the POV phase, telemetry from IoT Hub stops flowing to the hot path. The cold path continues to work.
What should you do to restore the hot path?
During the POV phase, you connect a device to IoT Hub and start sending telemetry messages.
You need to verify the content of the messages received by IoT Hub during the POV phase.
What should you use?
You need to design a module deployment strategy that meets the device requirements. What should you create?
You need to recommend the format of telemetry messages to meet the POV requirements.
What should you recommend?
You need to meet the monitoring requirements for device metrics. What should you configure?
You need to configure a gateway for the child devices. The solution must meet the networking requirements. Which gateway pattern should you use?
You need to develop a messaging app that meets the technical requirements. Which shared access policy should you use?
You need to configure loT module routing to meet the device requirements.
How should you complete the route? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
You need to the configure the device parameters to meet the device requirements. Which file should you update on each device?
You have an Azure IoT solution that includes a basic tier Azure IoT hub named Hub1 and a Raspberry Pi device named Device1. Device1 connects to Hub1.
You back up Device1 and restore the backup to a new Raspberry Pi device.
When you start the new Raspberry Pi device, you receive the following error message in the diagnostic logs of Hub1: "409002 LinkCreationConflict."
You need to ensure that Device1 and the new Raspberry Pi device can run simultaneously without error.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
You are prototyping an loT edge solution.
You are creating a deployment manifest for an loT edge device that will connect to an Azure loT hub. Which two modules should you include in the manifest? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
HA.
You have an Azure IoT hub that uses a Device Provisioning Service instance to automate the deployment of Azure IoT Edge devices.
The IoT Edge devices have a Trusted Platform Module (TPM) 2.0 chip.
From the Azure portal, you plan to add an individual enrollment to the Device Provisioning Service that will use the TPM of the IoT Edge devices as the attestation mechanism.
Which detail should you obtain before you can create the enrollment.
You have an Azure loT solution that includes an Azure loT hub and a Device Provisioning Service instance.
Several enrolled devices are stolen.
You need to prevent the stolen devices from connecting to the loT solution. The solution must prevent the devices from re-enrollment and must be implemented as soon as possible.
What should you do?
You have an Azure loT hub.
You need to configure an Azure function that will process loT Hub messages when the messages arrive at the loT hub. The solution must NOT require additional services or solutions deployed.
