質問 6

A customer has noticed that Client Band Select is enabled and no clients are utilizing the 5 GHz band.
Which three parameters must be met to ensure that wireless clients use the 5 GHz band?
(Choose three.)

（A）Ensure that the WLAN has 802.11a enabled.

（B）Ensure that the co-channel interference has not exceeded -85 dBm.

（C）Ensure that the client is dual-band capable.

（D）Ensure that channel bonding is enabled on the WLAN.

（E）Ensure that the client is receiving RSSI above the minimum band select RSSI threshold.

（F）Ensure tha the UNII-2 extended channels are enabled on the 802.11a radios.

質問 7

A community bank has three campus locations and one HQ with the data center operations. Each campus location has four Cisco Catalyst 9120 APs. The data center has a Catalyst 9800 WLC with eight Catalyst 9120 APs. Poor WAN uplinks cause impacted branch AP and wireless client connectivity back to HQ, and each campus location is now planned to have its own EWC controller based on C9120 AP to keep traffic local. This new design must accommodate these requirements:
- Guest WLAN will be routed locally.
- Employee WLAN must be authenticated 802.1x PEAP via HQ data center
ISE but can pass traffic locally once authenticated.
- HQ WLC will be the primary backup WLC for each WLC.
Which design approach should the consulting engineer take?

（A）Two C9120 campus APs must be converted to EWC mode, one for the active controller and the other for standby set as N+1 backup. The campus guest WLAN will use local web auth on guest VLAN, and employee WLAN will need the HQ AAA server added to EW

（B）One C9120 AP in each campus must be converted to EWC mode, and the preferred controller is set to that AP with HQ WLC set as N+1 backup. The campus guest WLAN will use local web auth on guest VLAN, and employee WLAN will need the HQ AAA server to be added to EWC.

（C）One C9120 campus AP must be converted to EWC mode, and the preferred controller is set to that AP with HQ WLC should be paired as mobility peer and configured as N+1 backup. The campus guest WLAN will use local web auth on guest VLAN. The campus employee WLAN will need the guest anchor back to the HQ employee WLAN.

（D）Two C9120 campus APs must be converted to EWC mode, one for the active controller and the other for standby with HQ WLC set as N+1 backup. The campus guest WLAN will use the guest anchor to HQ WLC for guest VLAN access, and employee WLAN will need the HQ AAA server to be added to EWC and then use that to perform the 802.1x authentication.
