Used to gather information about IoT devices, such as manufacturer details, geographical location, IP address, hostname, and open ports. Which tools fit this description?

• A. Shodan, Censys, and Thingful
• B. IoT device information gatherers such as Shodan, Censys, and Thingful
• C. Image search engines
• D. FTP search engines

Answer: (B)

This item tests how to gather information about IoT devices from the internet. Tools that index and enumerate internet‑connected devices provide the exact data described—manufacturer details, geographical location, IP address, hostname, and open ports. Shodan, Censys, and Thingful are IoT device information gatherers: they continuously scan the public internet, collect banners and service fingerprints, map devices to IPs and locations, and attach metadata like vendor and device type. They enable searching by vendor, device type, port, and location to build a profile of what IoT devices are exposed where. Image search engines focus on finding pictures, not device metadata or ports, and FTP search engines target FTP servers rather than providing a broad view of IoT devices with vendor and port information. So, the tools described are the IoT device information gatherers.
