Which Bluetooth tool is used to query a device’s Service Discovery Protocol (SDP) information?

• A. Netstat
• B. sdptool Service Discovery Protocol (SDP)
• C. Ping
• D. Tracert

Answer: (B)

SDP is the Bluetooth mechanism that lets devices advertise and discover the services another device offers. To see what a nearby Bluetooth device can do, you query its SDP records. The tool used for this in many environments is sdptool, part of the BlueZ Bluetooth stack. It communicates with the remote device using SDP and returns the available services, their UUIDs, names, and attributes. That makes it the natural choice for extracting a device’s SDP information. The other options are meant for IP networking: Netstat shows active connections, Ping tests reachability, and Tracert traces the path to a host, none of which fetch Bluetooth SDP data.
