300-360 Question #194: Real Exam Question with Answer & Explanation
The correct answer is B: Check the RF levels of the first AP as the client moves toward the second AP. Client 'bouncing' between APs (also called the sticky client problem) occurs when the roaming thresholds are not properly balanced between two APs. Checking the RF signal levels of the first AP as the client moves toward the second AP (B) reveals whether the first AP is holding o
Question
Options
- ACheck if the roaming settings in the AP are set properly for non-CCX clients
- BCheck the RF levels of the first AP as the client moves toward the second AP
- CCheck the client RSSI and SNR levels for both APs at the roaming point
- DSimplify 802.1X/EAP by moving from external RADIUS to local authentication
- ECheck that the client roaming parameters are set properly
Explanation
Client 'bouncing' between APs (also called the sticky client problem) occurs when the roaming thresholds are not properly balanced between two APs. Checking the RF signal levels of the first AP as the client moves toward the second AP (B) reveals whether the first AP is holding on to the client too long with a still-adequate signal. Checking the client RSSI and SNR levels for both APs at the roaming point (C) identifies the overlap zone where the client switches associations, allowing you to tune the transition threshold. Option A (CCX roaming settings) and E (client roaming parameters) are configuration items that might help but are not primary diagnostic checks. Option D (switching to local authentication) addresses authentication latency, not the bouncing/oscillation behavior.
