A mobile workstation in a factory contains an AP that is configured as a workgroup bridge. When the workstation moves, it loses connectivity and disrupts operation. What can the engineer implement…

While 802.1X authentication provides strong security, it requires a full authentication process with each roam to a new AP, which can lead to significant delays and connectivity loss, exacerbating roaming issues rather than minimizing them.

Cisco Centralized Key Management (CCKM) is a Cisco proprietary fast roaming technology that allows clients, including workgroup bridges, to roam between access points without a full 802.1X re-authentication. This significantly reduces the time taken for re-association and key exchange, preventing connectivity loss during movement.

AES (Advanced Encryption Standard) is an encryption method that provides robust security, but it does not directly address the speed or efficiency of the roaming process itself; fast roaming mechanisms like CCKM or 802.11r are needed for that.

The 'mobile station command' is not a standard or recognized command or feature in the context of Wi-Fi roaming solutions; this choice appears to be a distractor.
