IEEE 802.11r-2008 or fast BSS transition (FT), also called "fast roaming," Which 802.11 standard performs the PTK calculations in advance to enable fast client roaming?

The correct answer is A. 802.1 11r. 802.11r, Which is the IEEE standard for fast roaming, introduces a new concept of roaming where the initial handshake with the new AP is done even before the client roams to the target AP, which is called Fast Transition (FT). The initial handshake allows the client and APs to…

Explanation

802.11r, Which is the IEEE standard for fast roaming, introduces a new concept of roaming where the initial handshake with the new AP is done even before the client roams to the target AP, which is called Fast Transition (FT). The initial handshake allows the client and APs to do the Pairwise Transient Key (PTK) calculation in advance. These PTK keys are applied to the client and AP after the client does the reassociation request or response exchange with new target AP.
