Google Cloud Professional Data Engineer Exam 2025 - Free Practice Questions and Study Guide

The primary purpose of Google Cloud IoT Core is to securely connect and manage IoT devices and data streams. This service provides a scalable infrastructure for managing a large number of IoT devices, allowing organizations to easily onboard devices, configure settings, and monitor the health of those devices. It facilitates secure communication between devices and Google Cloud, ensuring that the data transmitted is encrypted and safe from unauthorized access.

By offering features such as device authentication, data ingestion, and integration with other Google Cloud services, IoT Core enables organizations to build robust IoT solutions that can gather and analyze data from various sources in real time. This foundation is essential for developing applications that can effectively leverage the vast amount of data generated by IoT devices, ultimately enhancing operational efficiency and enabling data-driven decision-making.

The other choices do not align with the primary functionalities of Google Cloud IoT Core. Developing machine learning models is better suited to services such as AI Platform. Cloud gaming services target a different market segment and are not the focus of IoT Core. Analyzing large datasets in real-time is typically handled by services like BigQuery or Dataflow, rather than IoT Core, which is primarily about device management and data collection.
