Exam 200-301 topic 1 question 328 discussion

At the beginning I thought that was D, but after reading this... "The SSID is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. Multiple access points on a network or sub-network can use the same SSIDs. SSIDs are case sensitive and can contain up to 32 alphanumeric characters." ref: https://content.cisco.com/chapter.sjs?uri=/searchable/chapter/www.cisco.com/content/en/us/td/docs/wireless/access_point/12-3_8_JA/configuration/guide/1238jasc/s38ssid.html.xml#:~:text=The%20SSID%20is%20a%20unique,up%20to%2032%20alphanumeric%20characters.

SSID doesn't have to be unique. I'm thinking that someone who posted questions about wireless on this site doesn't know the difference between SSID and BSSID, and there are questions in which someone deleted the B or though it's useless or idk. (There are questions here that spell truck instead of trunk etc.)

B is correct

"SSID: This is a human-readable, non-unique identifier used by the AP to advertise its wireless service." Source: 31Days Before Your CCNA

I think the word "unique" in this question has more to do with what the SSID does the job than the value itself. Therefore, even though the SSID is not a unique value, it is the unique value that performs the establishment and maintenance of wireless connectivity to wireless network devices. Following this criterion, and discarding all the remaining answers: B is the answer.

SSID is not unique identifier

B for sure

Since SSID is not required to be unique, the best answer is D.

B. SSID

The SSID is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. Multiple access points on a network or subnetwork may use the same SSIDs.

SSID is not unique though? It seems like the most correct option.
