出題：3

Based on a wireless network design, an engineer configured a primary and secondary controller for their APs. A power interruption caused the primary Cisco WLC to go down, and, as expected, all APs joined the secondary controller. When the primary controller came back up, all the APs remained joined to the secondary controller. Which approach must the engineer take for the APs to move back to the primary?

A. Set AP Failover Priority to Critical globally.

B. Set AP Failover Priority to 4 on each AP.

C. Set AP Fallback to Enabled on the primary controller.

D. Set AP Fallback to Enabled on the secondary controller.

- inter-controller roaming for guest users
Which two design approaches meet these requirements? (Choose two.)

A. Use secure mobility to pair controllers.

B. Use IPv6 across the wireless network.

C. Use EoIP for communication between controllers.

D. Use WLC software versions that support IRCM.

E. Use AVC on the anchor WLCs.

出題：8

A customer has two Cisco WLCs configured in a SSO cluster. The wireless network supports a large warehouse. The customer purchases new iPads to replace legacy scanners. Both devices connect to a single SSID named Scanning by using WPA2 Personal. The customer wants to use a standards-based method for fast roaming on the new iPads. Which approach meets the scanner requirement and still supports the legacy scanners?

A. Enable optimized roaming globally and enable FT PSK on the Scanning SSID.

B. Enable FT 802.1X and set Fast Transition to Adaptive for the Scanning SSID.

C. Enable optimized roaming globally and enable FT 802.1X on the Scanning SSID.

D. Enable FT PSK and set Fast Transition to Adaptive for the Scanning SSID.

A school deploys a Cisco wireless infrastructure in its classrooms to support a high density of mobile devices. The network administrator wants to bond channels in groups of two and only allow APs to send 802.11 management frames at 24 MB. What should be included in the design to accomplish this objective?

A. Set the channel width for 802.11a to 40 MHz and set data rates to 24 MB and Supported.

B. Set the channel width for 802.11a to 40 MHz and set data rates to 24 MB and Mandatory.

C. Set the channel width for 802.11b to 40 MHz and set data rates to 24 MB and Supported.

D. Set the channel width for 802.11b to 40 MHz and set data rates to 24 MB and Mandatory.

出題：12

Refer to the exhibit. Client A is roaming from AP1 on WLC1 to AP2 on WLC2. The client roams between two APs registered to two different controllers. The WLAN on the two controllers is on a different subnet. Which scenario explains the client's roaming behavior?

A. The client database remains in the mobility anchor controller and it is not copied or moved.

B. The client database entry is different than that of Layer 2 roam because the client database is neither moved nor copied into the new controller.

C. The client database entry is different than that of Layer 2 roam. (Instead of moving, it copies the database to the new controller.)

D. The client database entry is different than that of Layer 2 roam. (Instead of copying, it moves the database to the new controller.)
