b. Association ID
c. Identity request
d. Access-request

Answer 2

Association ID

Question 3

a. 802.11k
b. 802.11v
c. Fast transition
d. None, the station decides when to roam

Answer 4

None, the station decides when to roam

Question 5

What type of frame is displayed?

Answer 5

RADIUS Frame (Add photo)

Question 6

Which of the following describes OTA Fast Transition?
a. Station sends a reassocation frame directly to the target AP
b. station sends an association to target AP through current AP
c. station sends an association frame directly to the target AP
d. Station sends reassociation frame to target AP through current AP

Answer 6

station sends reassocation frame directly to the target AP

d. would be over the DS Fast Transition

Question 7

a. the destination and receiver MAC address fields are set to the BSSID of the current AP
b. the receiver and transmitter MAC address fields are set to the BSSID of the current AP
c. the destination and receiver MAC address fields are set to the MAC address of the station
d. the destination and receiver MAC address fields are set to the BSSID of the target AP

Answer 7

the destination and receiver MAC address fields are set to the BSSID of the target AP

d. 802.11r FT Over-the-DS Reassociation Request

Answer 8

802.11r FT Over-the-DS Reassociation request (add photo)

Question 9

r = Fast Transition
v = “assisted” roaming
h = RRM/TPC

Question 10

Which of the following describes PMK Caching?
a. Station roams back to previously associated AP and skips EAP frame exchange
b. Station roams back to target AP, already preauth, skips EAP exchange
c. Station is preauthed to all neighboring APs
d. Station roams to a target AP, already preauth, skips the 4-way handshake

Answer 10

Station roams back to a previously associated AP and skips EAP exchanges
