Joe, a technician, wants to create a PAN with his smart phone and laptop. Which of the following functions must be enabled on the laptop?

ICS (Internet Connection Sharing) is a Windows feature that allows a connected PC to share its internet connection with other devices, but it is not the wireless radio technology required to establish a PAN.

Virtualization allows a single physical machine to run multiple operating systems simultaneously and has no role in enabling short-range wireless PAN connectivity between physical devices.

Bluetooth is the wireless protocol specifically defined for Personal Area Networks, enabling devices within close proximity - typically up to 10 meters - to pair, communicate, and share data. Enabling Bluetooth on the laptop allows it to discover and connect to the smartphone to form a PAN.

Wi-Fi is used to connect devices to a local area network or the internet via a wireless access point and operates as a WLAN technology, not the short-range PAN technology that Bluetooth provides.
