You are configuring an SSID thatisusing 802.

The question asks for the reason for using WPA3-Enterprise (CCM-128) when deploying Wi-Fi 6 networks.

WPA3-Enterprise Modes:

CCM-128:Uses AES-CCMP-128 (same cipher as WPA2). Its main purpose is to provide a transition path from WPA2 to WPA3. It allows both WPA3-capable and WPA2-only clients to connect to the same SSID. It enforces Protected Management Frames (PMF, 802.11w) when possible(required for WPA3, optional for WPA2). It's often called "Transition Mode" or "Compatibility Mode".

GCMP-256:Uses stronger AES-GCMP-256. It operates in "WPA3-Only Mode" and doesnotallow WPA2 clients.

Wi-Fi 6 (802.11ax) & WPA3:Wi-Fi 6 certification requires support for WPA3.

Analysis of Options:

A: Incorrectly calls CCM-128 "192-bit mode" and "WPA3 only".

B: Correctly calls CCM-128 "Transition Mode" and states it allows WPA2 clients.

C: Correctly calls CCM-128 "Compatibility Mode" and states it allows WPA2 clients. "Compatibility Mode" and "Transition Mode" are used interchangeably for this WPA3 mode.

D: Incorrectly calls CCM-128 "Only Mode" and states no WPA2 support.  

Conclusion:Both Option B and Option C accurately describe WPA3-Enterprise (CCM-128). It is designed as a transition/compatibility mode to allow environments to adopt WPA3 features (like mandatory PMF for capable clients) while still supporting legacy WPA2 clients on the same network during the migration period. Selecting either B or C would be functionally correct based on common terminology.
