Actual exam question for CWNP's CWNA-109 exam

Question #: 28
Topic #: 4

An 802.11-based network uses an AP and has several connecting clients. The clients include iPhones, iPads, laptops and one desktop. What WLAN use case is represented?

AAd-hoc

BWPAN

CBSS

DIBSS

Show Suggested Answer

Suggested Answer: C

A BSS (Basic Service Set) is a WLAN use case that represents an 802.11-based network that uses an AP (Access Point) and has several connecting clients. The AP acts as a central point of coordination and communication for the clients, which can include iPhones, iPads, laptops, desktops, or any other devices that have Wi-Fi capabilities. A BSS can be identified by a unique BSSID (Basic Service Set Identifier), which is usually the MAC address of the AP's radio interface. A BSS can also be associated with an SSID (Service Set Identifier), which is a human-readable name that identifies the network.Reference:, Chapter 1, page 23; , Section 1.1

BSS makes sense, but I thought IBSS was for peer-to-peer only?

Not sure about that, looks pretty standard to me.

Wait, isn't this more like an ad-hoc network?

Definitely a BSS setup with that AP and multiple clients.

I keep mixing up BSS and IBSS. I hope it's not the ad-hoc one because that doesn't fit with the AP setup.

I practiced a question like this before, and I think the answer is C for BSS since it involves an access point.

I'm not entirely sure, but I remember something about BSS being related to APs and clients. Could that be it?

I think this is about the Basic Service Set, right? It sounds familiar from the study materials.

BSS, got it. That makes sense - the access point is coordinating the wireless clients, which is the basic building block of an infrastructure WLAN.

Okay, let me think this through. The question mentions an AP and multiple client devices, so that rules out ad-hoc and IBSS. WPAN is for personal area networks, which doesn't seem to fit. I'm going to go with BSS as the most likely answer.

Hmm, I'm a bit unsure about this one. The devices listed seem to indicate a typical home or small office network, but I'm not sure which WLAN use case that would correspond to.

This looks like a straightforward question about 802.11 network topologies. I think the key is to identify the devices mentioned and the use of an access point.
