Selected Answer: D D is the right answer. SSID (Service Set Identifier) is a unique name assigned to a wireless network.

I admit that I was wrong because APs can be named the same. That leaves option D. as the only choice that I reluctantly agree with. Poorly worded question.

SSID (Service Set Identifier) is a unique name assigned to the AP. A WLAN's name is set by the network administrator and can be different from the APs connected to it.

"The SSID is a unique identifier that 'wireless network devices' use to establish and maintain wireless connectivity." https://www.cisco.com/c/en/us/support/docs/interfaces-modules/security-modules-routers-switches/116586-config-ap-00.html
