Question
A consulting engineer on a brownfield deployment must improve the roaming experience of legacy wireless handheld scanners on a wireless network with a Cisco Catalyst 9800-80 WLC and Cisco 91301 APs. The requirement is that when the handheld scanner drops below -75 dBm in RSSI, the WLC should disassociate the scanner so that the scanner looks for a better connection to roam. Which feature must the engineer enable on the controller?
Options
- Aassisted roaming
- Bfast BSS transition over-the-air
- Coptimized roaming
- Dfast BSS transition over-the-DS

Explanation
Optimized Roaming is a proprietary Cisco feature designed to combat the "sticky client" problem, which is common with older, legacy wireless devices like the described handheld scanners. This feature allows the Cisco Wireless LAN Controller to proactively disassociate a client when its received signal strength (RSSI) or data rate falls below a configurable threshold (in this case, -75 dBm). By forcing the client off the current Access Point (AP), the client device is then compelled to scan and seek out an alternative AP with a better signal, thereby improving the roaming experience and overall network performance.
