AZ-220試験無料問題集「Microsoft Azure IoT Developer 認定」

You have an Azure loT solution that contains an Azure loT hub and 100 loT devices. You deploy Microsoft Defender for loT to the devices. You need to configure alerts for the following events;
* An X.509 certificate is expired.
* Potential loss of data is detected.
* The number of unauthorized operations is outside the allowed range.
The solution must minimize administrative effort.
Which type of alert should you configure for each event? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

You plan to deploy a standard tier Azure IoT hub.
You need to perform an over-the-air (OTA) update on devices that will connect to the IoT hub by using scheduled jobs.
What should you use?

You create an Azure loT hub as shown in the following exhibit.

For each of the following statements select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

You have an Azure IoT Central application that monitors 100 IoT devices.
You need to generate alerts when the temperature of a device exceeds 100 degrees. The solution must meet the following requirements:
Minimize costs
Minimize deployment time
What should you do?

You have an Azure solution that contains an Azure loT Edge deployment.
You are configuring an Azure Stream Analytics Edge job as shown in the following exhibit.
How should you complete the query? To answer select the appropriate options m the answer area.
NOTE: Each correct selection is worth one point.

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have a Standard tier Azure IoT hub and a fleet of IoT devices.
The devices connect to the IoT hub by using either Message Queuing Telemetry Transport (MQTT) or Advanced Message Queuing Protocol (AMQP).
You need to send data to the IoT devices and each device must respond. Each device will require three minutes to process the data and respond.
Solution: You schedule an IoT Hub job to update the twin tags and you query for job progress.
Does this meet the goal?

You have an Azure IoT hub and 15,000 IoT devices that monitor temperature. The IoT hub has four partitions. Each IoT device sends a 1-KB message every five seconds.
You plan to use Azure Stream Analytics to process the telemetry stream and generate an alert when temperatures exceed a defined threshold.
You need to recommend the minimum number of streaming units to configure for Stream Analytics.
What should you recommend?

You have an Azure IoT Central application.
You need to connect an IoT device to the application.
Which two settings do you require in IoT Central to configure the device? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

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?
