Planned Changes ADatum is developing an Azure IoT solution to monitor environmental conditions. The IoT solution consists of hardware devices and cloud services. All the devices will communicate directly to Azure IoT Hub. The hardware devices will be deployed to the branch offices and will collect data about various environmental conditions such as temperature, humidity, air quality, and noise level. The devices will be wired by using Power over Ethernet (PoE) connections. ADatum is developing the solution in the following three phases: proof of value (POV), pilot, and production. Requirements. POV Requirements The POV phase will demonstrate that a technical solution is viable. During this phase, 100 devices will be deployed to the main office and Azure Stream Analytics will be connected to an IoT hub to generate real-time alerts. Stream Analytics will perform the following processing: - Calculate the median rate of the telemetry across the entire devices that exceed the median rate by a factor of 4. - Compare the current telemetry to the specified thresholds and issue alerts when telemetry values are out of range. - Ensure that all message content during this phase is human readable to simplify debugging. Requirements. Pilot Requirements During the pilot phase, devices will be deployed to 10 offices. Each office will have up to 1,000 devices. During this phase, you will add Azure Time Series Insights in parallel to Stream Analytics to support real-time graphs and queries in a dashboard web app. The pilot deployment must minimize operating costs. Requirements. Production Requirements The production phase will include all the offices. The production deployment will have one IoT hub in each Azure region. Devices must connect to the IoT hub in their region. The production phase must meet the following requirements: - Ensure that the IoT solution can support performance and scale targets. - Ensure that the IoT solution support up to 1,000 devices per office. Top-Recommended AZ-220 Exam Questions [2022] Pass Microsoft AZ-220 Exam - Minimize operating costs of the IoT solution. Requirements. Technical Requirements Datum identifies the following requirements for the planned IoT solution: - The solution must generate real-time alerts when a fire condition is detected in an office. All the devices in that office must trigger an audible alarm siren within 10 seconds of the alert. - A dashboard UI must display alerts and the system status in real time and must allow device operators to make adjustments to the system. - Each device will send hourly updates to IoT Hub. Condition alerts will be sent immediately. - Multiple types of devices will collect telemetry that has different schemas. - IoT Hub must perform message routing based on the message body. - Direct methods must be used for cloud-to-device communication. - Reports must be provided monthly, quarterly, and annually. - Stored data queries must be as efficient as possible. - The device message size will be under 4 KB. - Development effort must be minimized. Requirements. Throttle and Quotas The relevant throttles and quotas for various IoT Hub tiers are shown in the following table. Requirements. IoT Hub Routing You plan to implement IoT Hub routing during the POV phase as shown in the following exhibit.

A. the Device Disconnected events B. the device twins C. the Connections logs D. the device credentials Answer: A Explanation: The IoT Hub publishes the Microsoft.Devices.DeviceDisconnected event type, which is published when a device is disconnected from an IoT hub. Reference: https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-event-grid#event- types 5. 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? A. Trusted Platform Module (TPM) 1.2 attestation B. symmetric key attestation C. X.509 certificates Answer: B Explanation: A common problem with many legacy devices is that they often have an identity that is composed of a single piece of information. This identity information is usually a MAC address or a serial number. Legacy devices may not have a certificate, TPM, or any other security feature that can be used to securely identify the device. The Device Top-Recommended AZ-220 Exam Questions [2022] Pass Microsoft AZ-220 Exam Provisioning Service for IoT hub includes symmetric key attestation.

Send cloud-to-device messages to the IoT devices. B. Use the heartbeat pattern to send messages from the IoT devices to iothub1. C. Monitor the connection status of the device twin by using an Azure function. D. Enable the collection of the Connections diagnostics logs and set up alerts for the connected devices count metric. Answer: D Explanation: Scenario: You discover connectivity issues between the IoT gateway devices and iothub1, which cause IoT devices to lose connectivity and messages. To log device connection events and errors, turn on diagnostics for IoT Hub. We recommend turning on these logs as early as possible, because if diagnostic logs aren't enabled, when device disconnects occur, you won't have any information to troubleshoot the problem with. Step 1: 7. You use Azure Security Center in an Azure IoT solution. You need to exclude some security events. The solution must minimize development effort . What should you do? A. Create an Azure function to filter security messages. B. Add a configuration to the code of the physical IoT device. C. Add configuration details to the device twin object. D. Create an azureiotsecurity module twin and add configuration details to the module twin object. Answer: D Explanation: Properties related to every Azure Security Center for IoT security agent are located in the agent configuration object, within the desired properties section, of the azureiotsecurity module. To modify the configuration, create and modify this object inside the azureiotsecurity module twin identity. Note: Azure Security Center for IoT's security agent twin configuration object is a JSON format object. The configuration object is a set of controllable properties that you can define to control the behavior of the agent. Top-Recommended AZ-220 Exam Questions [2022] Pass Microsoft AZ-220 Exam These configurations help you customize the agent for each scenario required. For example, automatically excluding some events, or keeping power consumption to a minimal level are possible by configuring these properties.
