How to Configure 802.11v BSS Transition for Optimized Roaming?
A network engineer is working for an enterprise where most of the laptops support 802.11v. To optimize the client roaming experience, configuration changes must be made on the corporate SSID to force clients to use the best APs based on the 802.11 v BSS transition message. Which configuration meets this requirement?

It tests the WLC feature that sends 802.11v BSS Transition Management Requests via optimized roaming; the trap is confusing coverage hole detection or 802.11k neighbor reports with actual 802.11v steering.
This question tests how to configure a Cisco WLAN to use 802.11v BSS Transition and optimized roaming to steer clients to the best AP. The correct setup is enabling the BSS transition option with an optimized roaming timer on the corporate SSID.
Many learners pick A or C because 'disable dissociation imminent' sounds client-friendly, but that setting prevents the WLC from forcing a client off a poor AP; coverage hole detection is unrelated to BSS transition steering.

Expert Analysis
Why the Answer Is Correct
Option B enables the 802.11v BSS Transition option and configures an optimized roaming timer on the corporate SSID, which is exactly how a Cisco WLC uses BSS Transition Management Requests to steer clients. Optimized roaming monitors client RSSI; when the client is below the threshold, the AP sends a BSS Transition Management Request telling the client to move to a better AP. The optimized roaming timer defines how long the AP waits for the client to comply before disassociating it, so the client is effectively forced to use the best AP. This matches the requirement that most laptops support 802.11v and that the SSID must use the 802.11v BSS transition message to improve roaming.Why the Other Options Are Wrong
Option A enables BSS transition but disables dissociation imminent, which removes the enforcement mechanism and does not force the client to move. Option C adds coverage hole detection, a separate feature used to detect and remediate coverage gaps by adjusting power or data rates, and also disables dissociation imminent. Option D enables 802.11k, which provides neighbor reports to clients and is not the same as an 802.11v BSS Transition Management Request, and disabling coverage hole detection has no bearing on roaming. Only option B combines the 802.11v BSS transition feature with the optimized roaming timer that drives the BSS transition message.Community Comment Notes
All three comments agree that option B is the answer, with Nerdx1 giving the clearest technical explanation: an "unsolicited optimized roaming request is triggered" and the AP sends a BSS Transition Management Request, then disassociates the client if it does not move within the timer. Farhad123 simply says "B is right answer,optimized roaming", and Jonycici confirms "B is correct". The community consensus therefore aligns with the Cisco behavior of enabling BSS transition and using the optimized roaming timer on the SSID.Exam Strategy
Map the stem's key phrase '802.11v BSS transition message' to the WLC features 802.11v BSS Transition and Optimized Roaming Timer. Eliminate options that add unrelated features such as coverage hole detection or 802.11k unless the question explicitly asks for neighbor reports or coverage remediation.
Frequently Asked Questions
Why is coverage hole detection not part of the correct answer?
Coverage hole detection adjusts radio power or data rates when clients hit low RSSI thresholds; it does not send the 802.11v BSS Transition Management Request used for client steering.
What does the optimized roaming timer do on the WLC?
It sets how long the AP waits after sending a BSS Transition Management Request for the client to move to a better AP before the AP disassociates the client.
