Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

What is a fully managed IoT Software-as-a-Service solution for connecting physical and digital worlds?

1. Azure HD Insight

2. IoT Hub

3. Azure IoT Central

4. AWS IoT

The correct answer is: Azure IoT Central

The correct answer is Azure IoT Central because it is specifically designed as a fully managed Software-as-a-Service (SaaS) offering that simplifies the process of connecting physical assets, such as sensors and devices, to the digital world. Azure IoT Central provides a user-friendly interface and allows organizations to quickly build, deploy, and manage IoT solutions at scale without the need to manage the underlying infrastructure. It streamlines the integration of IoT devices with backend analytics and applications, enabling users to visualize data, monitor device performance, and implement business logic with minimal development effort. Additionally, Azure IoT Central encompasses built-in security, compliance features, and customizable templates, making it a robust choice for businesses looking to capitalize on IoT technology effortlessly. Other choices do not fit the description of a fully managed SaaS IoT solution. For instance, IoT Hub is more of a Platform-as-a-Service offering that requires more hands-on management and configuration, focusing on device connectivity and communication rather than providing an out-of-the-box IoT application environment like Azure IoT Central.
