A. B. C. D.

C.

The correct answer is B. " Cisco CKM roaming is unsupported between local mode APs and H-REAP APs."

H-REAP (Hybrid Remote Edge Access Point) is a feature in Cisco Wireless LAN Controllers (WLCs) that allows remote branch offices to operate without a connection to the central WLC. H-REAP APs have the ability to locally switch WLAN traffic, which can significantly reduce the amount of traffic sent over the WAN link, resulting in better performance.

FlexConnect is another feature that allows local switching of WLAN traffic. FlexConnect APs can function in two modes: centrally switched mode and locally switched mode.

Now, let's examine the statements and see which ones are true:

A. Cisco CKM roaming is supported within an H-REAP group of APs. This statement is true. Cisco CKM ( Cisco Centralized Key Management) roaming is supported within an H-REAP group of APs. CKM is a fast roaming mechanism that allows clients to roam quickly and securely between access points without having to re-authenticate.

B. Cisco CKM roaming is unsupported between local mode APs and H-REAP APs. This statement is false. CKM roaming is supported between local mode APs and H-REAP APs. However, CKM roaming is not supported between H-REAP APs in standalone mode and local mode APs.

C. HREAP AP in standalone mode can authenticate new clients for CCKM roaming. This statement is true. An H-REAP AP in standalone mode can authenticate new clients for CKM roaming. However, it cannot perform key caching for fast roaming.

D. H-REAP APs can have some locally switched WLANs and some centrally switched WLANs. This statement is true. H-REAP APs can have some WLANs that are locally switched and some that are centrally switched. This allows for greater flexibility in designing the wireless network.

In summary, the false statement about H-REAP and FlexConnect APs on a Cisco WLC is B. Cisco CKM roaming is supported between local mode APs and H-REAP APs.
