Exam 200-301 topic 1 question 126 discussion

Terrible question A. uses the maximum of 32 alphanumeric characters This is not a function, its a requirement, but it is true. B. controls the speed of the Wi-Fi network SSID has nothing to do with speed. C. used exclusively with controller-based Wi-Fi networks Any WLAN can have an SSID including autonomous which are not controller based. D. supports a single access point Multiple access points can share the same SSID. E. broadcasts by default The checkbox for broadcast is checked by default so this is true, still not a function. A and E are true but are not functions.

These are correct

The admin answer is fine, I guess, if you haven't yet gotten deep into your reading. But if you have, definitely go with E instead of D. APs periodically broadcast beacon signals so that clients/users/end-hosts can actually find them. Even if you hide your SSID, it will still appear on wifi-analyzers; it just won't show the actual SSID, the channel would show that it's being used and will show the signal strength but would be marked as "hidden". So, if you know the actual SSID, and have the passphrase, and you see the antenna pinging, then it's there, broadcasting, until you turn it off.

ok the people say AE , the Admin say AD are the correct which one is the more accurate

A is clear, but why D ? For me E makes more sense

A & E are correct

A AND E IS THE ANWSER

According to Cisco, the WLAN name and SSID can have up to 32 characters, so "A" is correct. "E" is also correct, and I also think that "D" is correct to, since it CAN support a single access point.

I choose AE

terrible question

AE is correct but also they are not function :)

A isn't correct. The maximum of 32 *can* be used, but doesn't have to be 32. B isn't correct. SSID has nothing to do with speed C isn't correct. whether controller based or stand-alone APs, SSIDs are used either way. D is correct. SSIDs support a single access point. They also support multiple APs. But a single is also supported, so this is a true statement. E is correct. It broadcasts by default. Although it can be hidden.

Explanation of D The SSID string must be consistent across all APs so that wireless clients can roam from one AP to another connected to their WLAN SSID. But when you have two SSIDs on an AP, a unique BSSID (logical AP) is generated for each SSID and its WLAN on the AP. So perhaps the answer is referring to the unique AP that is created by each SSID. The same AP can be composed of several logical APs with their independent BSSID (DFWMAC) for each SSID created. Being a single (logical) AP for each SSID on the AP. Remembering that in another AP the same SSID will have a different BSSID (DFWMAC).

D is definitely not true.. I have 8 APs at my work place and they all connect through the same ssid.

ChatGPT says: The two functions of SSIDs (Service Set Identifiers) are: Identification: An SSID is used to identify a specific wireless network, allowing devices to connect to the correct network. Authentication: An SSID is also used to authenticate devices attempting to connect to the wireless network. Devices must provide the correct SSID along with any required credentials (such as a password or certificate) in order to connect. Therefore, options A and E are partially correct as they relate to the characteristics of SSIDs, but they do not accurately describe the functions of an SSID. Option B is not a function of SSIDs. The speed of the Wi-Fi network is primarily determined by the wireless standard and the capabilities of the devices connected to it. Option C and D are also not accurate as SSIDs are used in both controller-based and controller-less Wi-Fi networks, and can be used to support multiple access points.

C is wrong because its not only used in SDN ,

I follow with the sentiment question is bad but A,E are facts as I haven't heard of any APs that come with broadcast off by default. D is debatable because when multiple APs use the same SSID it become ESSID. Can multiple APs use the same SSID? Yes. Is it it called something different when multiple APs use the same SSID? Yes. Would that mean an SSID support only one access point no. Thus the conundrum of by definition yes but in practice no.
