Internet of Things (IoT) Practice Exam 2026 – Comprehensive Prep Resource

A significant benefit of using an IoT gateway is its enhanced security features. IoT gateways serve as a critical point of control between the edge devices and the cloud or central systems. By implementing security protocols at the gateway level, these devices can help filter and manage the data traffic, protect sensitive information, and mitigate potential attacks before they reach the central network. This can include functions like data encryption, authentication of devices, and real-time monitoring of data streams for any unusual behavior.

The importance of security in IoT cannot be overstated, as the interconnectivity of devices can make them vulnerable to cyber threats. By establishing robust security measures within the gateway, organizations can better protect their networks and the integrity of the data being transmitted.

In comparison, while the other options such as having a redundant power supply, achieving compatibility with all devices, or decreasing device count may provide benefits in specific contexts, they do not capture the fundamental role of an IoT gateway as effectively as the strong focus on enhanced security.
