Which two metrics are shown by default on the overview page for your IoT hub?

The correct answer involves understanding what information is readily displayed on the overview page of an IoT Hub in Azure. The default metrics typically focus on the core functionalities that users need to monitor to assess the health and activity of their IoT deployments.

Telemetry data sent is crucial as it represents the volume of data being communicated from devices to the cloud, providing insights into device activity and application behavior over time. Successful twin reads from the back end indicate that the device twin, which contains information about the device’s state and configuration, is being accessed correctly. This metric is integral for understanding the synchronization between the cloud and devices.

Together, these metrics give a clear view of both device communication and the successful management of device states. They are essential for developers and administrators who want to quickly assess whether their IoT solutions are performing effectively without delving too deeply into more complex or less critical metrics.

The other options focus on metrics that may provide important insights but are not typically highlighted on the initial overview page of the IoT Hub. For instance, while device-to-cloud messages and cloud-to-device messages are certainly important, they might not encompass the broader overview that includes twin operations. Similarly, properties and settings provide configuration details rather than operational metrics, and while device twin operations are
