What is the purpose of the service-set identifier?

Answer options

• C. It identifies the wired network to which a user device is connected.
• D. It identifies a wireless network for a mobile device to connect.

Correct answer: D

Explanation

The correct answer is D because the service-set identifier (SSID) specifically refers to the name of a wireless network that mobile devices use to establish a connection. Options A, B, and C incorrectly describe the SSID's function in relation to other types of networks or connections.
