I read, googled and asked a Cisco expert, they all say 802.11R. This is important :"Reduces the number of packets that are exchanged between the client and an AP"

Selected Answer: B

802.11r skips the EAPoL packages. 802.11k is an ammendment that the AP helps the client choosing a new AP to roam to, but the roaming procedure itself won't change.

Provided answer is correct, K setting allows for the removal of real time re-authentication between access points.

802.11k is an amendment that the AP helps the client choosing a new AP to roam to (it provides a list), but the roaming procedure itself won't change.

802.11r reduces the number of packets that are exchanged between the client and an AP. This means the roam itself occurs faster because the AP already has the client authentication credentials cached, resulting in fewer packets required between the client and the AP. https://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Mobility/RToWLAN/CCVP_BK_R7805F20_00_rtowlan-srnd/CCVP_BK_R7805F20_00_rtowlan-srnd_chapter_0101.html
