Free Microsoft AZ-220 Exam Actual Questions
The questions for AZ-220 were last updated On Jan. 21, 2023
You have IoT devices that connect to an Azure IoT hub.
From IoT Hub, you create an Event subscription to be notified when devices are registered to IoT Hub. You select webhook endpoint as a handler for the Event subscription.
Which two types of Event Grid messages will be received by the webhook? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
Microsoft.Devices.DeviceCreated: Published when a device is registered to an IoT hub.
The first thing you want to do is handle Microsoft.EventGrid.SubscriptionValidationEvent events. Every time someone subscribes to an event, Event Grid sends a validation event to the endpoint with a validationCode in the data payload.

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 an Azure IoT solution that includes an Azure IoT hub, a Device Provisioning Service instance, and 1,000 connected IoT devices.
All the IoT devices are provisioned automatically by using one enrollment group.
You need to temporarily disable the IoT devices from connecting to the IoT hub.
Solution: You disconnect the Device Provisioning Service from the IoT hub.
Does this meet the goal?
Instead, from the Device Provisioning Service, you disable the enrollment group, and you disable device entries in the identity registry of the IoT hub to which the IoT devices are provisioned.

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.
Consider using jobs when you need to schedule and track progress any of the following activities on a set of devices:
Invoke direct methods
Update desired properties
Update tags
https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-jobs
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?
Automatic device management in Azure IoT Hub automates many of the repetitive and complex tasks of managing large device fleets. With automatic device management, you can target a set of devices based on their properties, define a desired configuration, and then let IoT Hub update the devices when they come into scope. This update is done using an automatic device configuration or automatic module configuration, which lets you summarize completion and compliance, handle merging and conflicts, and roll out configurations in a phased approach.

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 use cloud-to-device messages and watch the cloud-to-device feedback endpoint for successful acknowledgement.
Does this meet the goal?
IoT Hub provides three options for device apps to expose functionality to a back-end app:
Twin's desired properties for long-running commands intended to put the device into a certain desired state. For example, set the telemetry send interval to 30 minutes.
Direct methods for communications that require immediate confirmation of the result. Direct methods are often used for interactive control of devices such as turning on a fan.
Cloud-to-device messages for one-way notifications to the device app.
