Internet of Things (IoT) Practice Exam

What facilitates remote monitoring in IoT systems?

1. A. On-premises databases

2. B. Cloud connectivity

3. C. Isolated systems

4. D. Local servers

The correct answer is: B. Cloud connectivity

Cloud connectivity is essential for facilitating remote monitoring in IoT systems because it allows devices to transmit data over the internet to centralized servers. When IoT devices are connected to the cloud, they can send real-time data to cloud-based applications or dashboards, enabling users to monitor their status and performance from anywhere in the world. This accessibility is crucial for applications such as smart home management, industrial equipment monitoring, and environmental sensing. Cloud connectivity also offers scalability and flexibility, allowing for the integration of data from numerous devices and performing complex analyses without the need for significant local resources. Furthermore, it supports the use of IoT analytics, machine learning, and artificial intelligence, enhancing the effectiveness of monitoring and control systems. The other options, such as on-premises databases, isolated systems, and local servers, do not provide the same level of accessibility and scalability that cloud connectivity does. On-premises solutions may limit access to data to only local networks, while isolated systems lack the ability to connect to the internet, preventing remote monitoring altogether. Local servers offer some benefits but require direct access to the server rather than allowing remote connections via the cloud.
