Certified Information Systems Security Professional (CISSP) Practice Exam

Bluetooth technology primarily facilitates personal area networks (PAN), allowing devices to communicate wirelessly over short distances. It is designed to connect devices such as phones, headphones, computers, and other peripherals in close proximity, typically within a range of about 10 to 100 meters, depending on the class of the device. The focus of Bluetooth is on creating a simple, efficient means of connection for personal devices without the need for wired connections, which aligns perfectly with the concept of a personal area network.

The other options do not accurately represent the primary function of Bluetooth. For instance, wired communications refer to traditional physical connections like Ethernet or serial connections, which Bluetooth specifically aims to eliminate. Additionally, wide area networks (WAN) involve broader geographical coverage typically handled by different technologies, such as cellular or satellite communications, rather than the short-range applicability of Bluetooth. Lastly, routing protocols for internet traffic concern the management and direction of data packets over networks, a function that is not related to Bluetooth's capabilities. Therefore, the central purpose of Bluetooth as a PAN wireless technology distinguishes it in the realm of communications.
