Which of the following is mobile device remote fingerprinting?

Mobile device remote fingerprinting is the process of identifying a device based on common characteristics shared by all devices of a certain type. Mobile device remote fingerprinting is a technique that can be used by attackers or defenders to gather information about a mobile device that is connected to a network or a web server, without having physical access to the device. Mobile device remote fingerprinting can be done by analyzing the network packets, the web browser headers, the device configuration, or the device behavior, and comparing them with a database of known device fingerprints. Mobile device remote fingerprinting can reveal various information about the device, such as the device type, the operating system, the firmware version, the browser type, the screen resolution, the installed applications, or the device location. Mobile device remote fingerprinting can be used for various purposes, such as device identification, device profiling, device tracking, device authentication, or device vulnerability assessment. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 4: Communication and Network Security, page 167. CISSP Practice Exam | Boson, Question 14.
