Discuss CWNP CWNA-109 Exam Topic 5 Question 38

You are implementing a multi-AP WLAN and fast secure roaming is essential. Which one of the following methods is an IEEE 802.11 standard method for fast roaming?

AFT

BOKC

CLoad balancing

DBand steering

Suggested Answer: A

FT (Fast Transition) is an IEEE 802.11 standard method for fast roaming. FT is defined in the IEEE 802.11r amendment and is also known as Fast BSS Transition (FBT) or Fast Secure Roaming. FT is a feature that allows a client station to quickly switch from one AP to another within the same ESS (Extended Service Set) without having to re-authenticate and re-associate with each AP. This reduces the latency and packet loss that may occur during roaming, thus improving the user experience and maintaining the security of the connection. FT works by using pre-authentication and key caching mechanisms that allow the client station and the APs to exchange security information before the actual roaming occurs.This way, when the client station decides to roam to a new AP, it can use a fast reassociation request and response that contain only a few fields, instead of a full authentication and association exchange that require more time and data.Reference:1, Chapter 9, page 367;2, Section 6.3

But what about B) OKC? It also helps with roaming, right?

Huey 3 months ago

I agree, A) FT makes sense. It’s designed for seamless transitions.

I think the answer is A) FT. It’s the standard for fast roaming.

Fast roaming? Sounds too good to be true!

Alison 3 months ago

I thought load balancing was more about traffic management?

Jules 4 months ago

Wait, isn't OKC also used for roaming?

Yen 5 months ago

Totally agree, FT is the standard method.

Martina 5 months ago

A) FT is the right answer for fast roaming!

Wilford 6 months ago

I practiced a question like this before, and I think FT was the answer, but I might be mixing it up with OKC.

Load balancing and band steering seem more about optimizing performance rather than fast roaming, right?

Kimbery 6 months ago

OKC sounds familiar too, but I can't recall if it's specifically for fast roaming or just for key caching.

I think I remember something about FT being related to fast roaming in WLANs, but I'm not entirely sure if it's the only standard method.
