How did the ISP likely know about the illegal downloading?

• A. The ISP monitored the internet traffic coming from each of the computers using the office's connection.
• B. The ISP checked employee emails.
• C. The ISP queried the office's credit card records.
• D. The ISP used GPS tracking on devices.

Answer: (D)

The key idea is tying a specific network action to a specific device. If a download happens over the office’s Internet connection, the ISP can see the traffic and note which device’s connection was used at that exact time. When devices in the office also have GPS or location-tracking data that’s accessible to the organization or the ISP, that location data can be matched with the timing of the download. By linking the device’s location (where the device was when the download occurred) to the network activity, the responsible device—and thus the person using it—can be identified. Emails or credit card records wouldn’t directly show who downloaded a file from the Internet, because those records pertain to messages or purchases, not the act of downloading over the network. GPS tracking provides the kind of location-to-action linkage that could reveal which device carried out the download.
