IoT Security uses MAC address, device manufacturer, and OS information to identify and classify devices via Device-ID.

''IoT Security uses passive network traffic analysis to fingerprint devices based on the MAC address, manufacturer, and operating system to ensure accurate classification.''

I'm leaning towards A. IP address, network traffic patterns, and device type seem like the most logical way to determine Device-ID for IoT security.

Ha! As if anyone would use hostname, application usage, and encryption method to identify IoT devices. That's just silly. I'm going with B.

The question seems straightforward, but I'm not sure if option D is a trick answer. Device model, firmware version, and user credential could also be used for Device-ID.
