Question 680
A voice WLAN introduces rapid roaming requirements, but the configuration has no support for the client-compatible 802.11r fast transition mechanism. Which ongoing operational safeguard best reduces the chance of recurrence?
Explanation
Correct Answer
This is a continuing control for the failure mode in which repeated full key exchanges during roaming can add latency beyond voice application tolerance. It complements the immediate fix instead of relying on a one-off correction.
Incorrect Answers
That control is useful for a different failure, such as when a visitor WLAN sends all guest traffic into a production data VLAN because its role mapping uses the employee default role. It would leave the present failure mode insufficiently addressed.
That control is useful for a different failure, such as when a deployment reports high AP client counts but users complain about slow uploads during busy classes. It would leave the present failure mode insufficiently addressed.
That control is useful for a different failure, such as when a lab SSID uses a pre-shared password and the organization needs different access per shared IoT device type. It would leave the present failure mode insufficiently addressed.
