CWDP CWDP Roaming and Client Mobility

Question 1

Which IEEE amendment defines fast BSS transition (FT), reducing roaming latency for real-time applications?

Accepted Answer

IEEE 802.11r

Answer

IEEE 802.11k

Answer

IEEE 802.11v

Answer

IEEE 802.11u

Question 2

What problem does IEEE 802.11k (Radio Resource Management) solve in roaming scenarios?

Accepted Answer

Provides clients with neighbor AP reports to accelerate target AP discovery

Answer

Reduces re-authentication time during roaming

Answer

Enables seamless IP address retention across subnets

Answer

Controls transmit power on the client device

Question 3

What is 'sticky client' behavior and why is it problematic in enterprise WLAN design?

Accepted Answer

Clients that maintain association with a distant AP despite a closer one being available

Answer

Clients that support 802.11r and roam too frequently

Answer

APs that do not release client associations after timeout

Answer

Clients configured to use 2.4 GHz exclusively

Question 4

In the 802.11r fast transition process, what is the role of the 'R0 Key Holder'?

Accepted Answer

The first AP in the mobility domain that derives the master session key

Answer

The RADIUS server that stores EAP credentials

Answer

The client that initiates the roam request

Answer

The controller that manages IP address assignment
